So, an interesting thing happened with my WPL 2-Speed. The 370 motor burned out on it and I replaced the motor with a $10 RedCat 370 motor and WOW it's sooo much faster and more powerful. I've seen people retro-fit the MN86k's 390 motor to the WPL 2-Speed, but just replacing it with a better 370 does the trick from my experience.
Dude you're the reason I'm in this game. Just started about 4 weeks ago after I bought that Xiaomi Jimny on sale just at the side off the street (basically just for fun). Saw your video running that to the hill, then saw your WPL C24-1 video. After looking at tons of WPL videos, Now I'm waiting for my C24-1 RTR, a C24 Kit + metal upgrades to be delivered! Your videos after very useful. Keep it up bud!
What a genius solution to such a silly problem. Its a coincidence you posted this video today, because I just put a 2 speed in my C14 and have been experiencing slipping in 1st gear. You can see the issue in my latest video on my channel. I was afraid I would have to tear my truck apart again to break down the gearbox. But I am going to go searching for some foam right now and see if that solves it! Thanks for posting this :)
Im so glad i have you on RUclips, you have cured my frustration with the gearbox, i have a b-16 and i love it but its my first ever 2 speed gearbox and it was slipping, now im back to trailing, thanks heaps buddy 👍🏻😎

Wow David, your ingenuity hits bullseye again on the slipping gear issue. I adopted the same solution using a piece of polystyrene tucked tight against the servo and it works perfectly well. Simple and easy fix. Thanks! ;) Cheers
Love your channel. Your channel is one of the channels that inspired me to get my first rc car and that was a rbr/c tube chassis crawler with wpl parts
The more I watch your vids is the more I really want to grab a couple of these WPLs and get to tinkering. Teally glad I found your channel brother✌👍✌👍✌👍👍
The Green Grease recommended at 8:25 is a good lube for RC since it is plastic and rubber-safe. A lot of lubes aren't and will weaken, soften or otherwise degrade plastic. Grease like that usually comes in big 14 oz tubes like David shows, which is a lot of grease for an RC model... I found out Green Grease also comes in 3 oz tubes (usually in 3-packs) for the mini grease guns so buying the 3-pack, keeping one for yourself and sharing the rest with your friends might be a good option. Then again, these WPL gears need a decent amount of grease because if you use a small amount, it will fly off the gears and stick to the walls of the gearbox. You want the gears 'bathed' in a sea of lube and if you have as many RC cars as David has, you might use up a big 14 oz tube in a year or two... especially if you drive outdoors and utilize submarine mode, hahaa
It's one one my favorites to run on my WPLs and MN models. I like the new gearbox that's in the C54-1 RTR and the new B36-3 RTR. Paired with a 370 motor and 1080 HW esc its a performer on trails.
Nice vid. These transmissions are pretty sweet. I actually blew apart a stock driveshaft (doing something stupid), so the trans is not the weakest link. The arm flex does seem to get worse over time but mine hasn't popped out of gear at all despite the flex being pretty significant right now (my reason for checking out this video). The C24 trucks are pretty awesome if you want to build a cheap crawler that can really climb
to anyone wondering what motor and gearbox to apply to their MN D90.. it’s this one. not the one speed. this motor/gearbox is much faster and has ability to go low speed high torque in first gear. also u will need a “gearbox riser” to apply to D90 without hitting chassis links… i kno this through much trial n error. this product is what you want
For some reason mine came a little short and didn't shift gears well, so I had to use another servo arm for it to work properly, but now it can shift great!
New to these little RC trucks and liking them alot! As for mods, this is my first one. Do you actually show installation? I'm nervous about taking my stock truck apart and not knowing how to properly install the two speed AND get it to work. There are so many videos out there, but you make it seem easy. I bought the two speed with servo. Then metal axles. Now to tear apart the truck and install it! Also, I bought the WPL transmitter with 3rd channel, so the receiver needs to be installed. I know this is so simple to you, but scary to me! Thanks for your time and videos.
STILL can't find a source for buying the newer tan colored stock gearbox, the older black ones all day long for about 4 bucks of course, and "Siamese 69" two of them is really good in a 2 axle with a pair of 130 motors. gives good grunt and a decent fast walking pace for a simpler 2ch Tx setup. tan gearbox about 1/2 that speed, better for climbing etc.
I have two c14s and two c24s purchased at the same time and all came with tan gearbox but one of the c14s had a 3 gear arrangement with a 10 tooth pinion and the rest so far are 12 tooth and 5 gears. Maybe old stock gears left over when they went to tan gearbox?
I'm not sure about the titanium color one. I have the brass looking ones and the black steel ones and they are pretty good mesh wise. Just a fyi most of the upgrade parts are not even made by WPL even if they say it on the listing. But they usually still work ok. Just mentioning it so people hopefully wont blame wpl for the quality of the upgrade parts like some people like to do lol.
@@RunThatRC When reinstalling the servo the plastic on the shifting part happened to slide closer to the spring, which effectively shortened the spring lol... thing is working good now. Lucky accident.
@@dashSlap Good to know. That's what I am running into now. It feels like it will require a lot of force to keep it in gear. Time to get to stretching or see if I can make the plastic part slip.
Awesome video. Plain talk about an important mod. Backed by real experience. Unbiased. Thanks! Transmission will be ordered as soon asy stupid ass quits typing!
Was the gearbox installed without drilling additional holes in the frame? I'm currently replacing a gearbox, and when I install the gearbox into the existing frame hole, it doesn't work well because it's not centered.
I have this 2speed and it makes some unstable noises. When the truck moves at slow speed it sort of jerks. As if the gears are not of proper size or off alignment. At slow speeds its noticeable where the truck moves fast slow fast slow motion. Am i having trouble with the gears binding?
usually when that happens to me there is something binding in the driveline somewhere. make sure everything is running free and smooth before you install the 2 speed.
After playing my rig for about half a year. I started experiencing the shift fork issue. At first I thought it was the plastic gears. Look at it, and it’s not. Then I noticed that my shift fork is loose. It can slide to the left a bit that makes it a bit far from the servo horn and cause the gears skipping. Can I permanently bond it with CA glue?
that's one way to try and solve it. I haven't experienced that issue yet with any of my 2 speed gearboxes (my luck maybe) my slipping is usually just a servo horn not engaging fully or slipping under load due to flexibility of servo mount.
@@RunThatRC I was sold a c 24 that had t be 15years old so has original esc . the steering servo is absoliute junk too has two little arms on top held together by a spring
@@RunThatRC but how you found out the pinion fit to your brushless motor? The brushless motor shaft and pinion size must have been different from the original. It would be a hard work to procure and change the pinion gear on the brushless motor.
Thanks for the tip for the bending servo! i have the same issue and maybe it will help :) but i have another problem running the combo. my motor lagging when i drive - do you have any suggestion? i'm running one of those cheap 30a escs but my friend got exactly the same problem running a way better hobbywing esc :( Thanks!
I know much time has passed since posting this video, but would you mind telling how you have connected the gear box servo to the receiver? I have a Dumbo x6 Transmitter and the servo in channel 3 in my C44 only makes a about 60 degrees turn instead of 90. Also thank you for posting all of the wpl videos, sometimes one can be lost without a good guide, since wpl (ans rbr/c ...) do not really care about that thing do much.
When I hit the 3rd channel transmitter button, the servo moves 90 degrees and returns back to 0 degrees. How do I change that to where it stays in the 90 degree position?
@@RunThatRC the controller has digital trim and dual rate adjustments. The instructions leave alot to be desired! I appreciate you taking the time to help Me out. Love your videos and enthusiasm.
im still running stock servo. All you have to do is mak sure its straight 90 when in low gear and no engagement when in high and mine have been pretty reliable.
Hi, I have the wpl 2 speed in my mn99. I also use the wpl metal drive shafts, however on the rear the drive shafts is too short and comes apart (Shaft does not stay in the holder). Which metal drive shafts do you use in your mn's with the wpl 2 speed? Thanks
Thanks for your fast response! They are the same length. I think the issue is because I mounted the 2 speed gearbox at least 1 cm higher on the chassis, I maxed out on the length of the driveshafts. Grtz Gary
Are you talking about fixing the 370 motor? Not sure what your asking. Maybe you want a install video of the 2 speed? Let me know which one? I'll try and help you out
Man love your vids, you've helped me a ton with MN and now WPL! I have C34 (I know should've gotten the kit!) And I'm wondering if you have advice for making shocks less bouncy? Or a link to good replacements! Thanks so much!
you can try cutting the top tightly wound spring section and that should help but will lower the truck slightly. I run stock springs just spary oil in the shock every now and then and they perform better once you put some running time on them.
So did you just use a jst plug on the motor? I just got my 2 speed and noticed that it does come with wires and the esc I got has a jst plug. Kinda a dumb question just wondering.
I just got 2 of them i ordered the new set. but i still got the old version. banggood needs some improving on inventory system ID. But what you think is the best version? havent tested mine but old version with spring sounds little better dunno.
I am on the same boat. I ordered it also and it showed the new ones in the picture but they sent me the ones with springs. So unfortunately I have no experience with the none spring version. Hopefully I will receive one when I order more. Cross fingers. On the other hand i haven't had much issue with the spring version other than the flexible shift servo mount. There are several ways to solve that minor issue. And no stripped gears to report yet.
Not sure if your referring to the all metal vs this or are you reffing to the other plastic gearbox with no spring? This one in the vid with the spring has been pretty good and reliable for me. Haven't run all metal long enough to say and the plastic without spring I tried to get but was never able to get that style gearbox so no experience with that one unfortunately.
Hi, can you please advise me on something, i seen that you work with a lot of wpl trucks, mine is still broking the diffs fromt or rear, once I’m forcing it a bit gone, i run 3 types of axels and they don’t survive more then 10 min....thanks
@@RunThatRC hi, thanks for your reply, that it was what I think too but the last one, titanium one I bought it all ready build and same thing....I don’t know....thanks anyway.
you would need the metal upgrades and hopefully they can handle more speed. These trucks where never meant to go fast. You can see how it goes but not my recommendation if you want speed. You would need so many upgrades and custom parts.
Thanks for the vid. I'm trying to figure out what I'll need to do to add this to my RTR 24C I just picked up. The controller has no function to work the servo... and no where on the ece to plug in an additional servo. Do I need to get a dif ece and controller to have this? Thank you!
Yes unfortunately you are correct. You will need a 3 channel tx/rx to use the 2 speed on the fly. You can however shift it manually with a small screwdriver by moving the servo horn. I do recommend getting better electronics on it as it will increase the performance and make it more controllable and enjoyable.
@@RunThatRC Thank you. It's been a few days with this truck and it's a lot of fun. I've ordered a 3ch controller, and a new reciever. I have the C24, will I need different drive shafts with the 2 speed? It's been tough to tell from vids. What would you recommend, the 2 speed trans, or the upgraded motor and metal gear box? Thanks again!
@@christopherdonnelly6255 2 speed wins for me. These are the driveshafts I recommend [US$10.80]1/16 Front And Rear Drive Shaft WPL JJRC 4WD RC Military Truck Car RC Parts from Toys Hobbies and Robot on banggood.com banggood.app.link/GvfYBXvgHX
@@RunThatRC Thanks for all the info... If you don't mind, one more question, please. Regarding the two speed trans. Is the lower speed all torque, and the higher one for top speed? I'm not too concerned with speed, torque is what I'm after with this. That said, it'll be nice to blast it around quickly between fields though with the high speed. Regardless, this two speed trans will make a huge improvement to performance, right? Thanks!
@@christopherdonnelly6255 yes the 2 speed has a lower gearing so the 370 motor has tons of torque. Enough to break plastic parts if you get binded up. The second gear isn't much faster than the stock 180 motor gearbox combo. Enough for walking it around to the next crawl spot.
Is there any difference in WPL 2 speed gearboxes for different cars that fit the 370 motor? I look for a slower gearbox for JJRC Q60 but there's no info about rpm on output shafts. ...or a motor that has less rpm but more torque =)
I know some companies make 2 speeds for these but the wpl official 2 speed are all the same. RBRC makes a metal 2 speed I believe and it has a lower low gear and a faster high gear. Very slightly but noticeable. Unfortunately I don't know the actual output rpm.
I dont know of im stupid but i had a servo issue and have changed servos. (Fir the 2 speed) for some reason i cant seem to get the horn to line up and have the low gear with drag brake and high gear with high gear. Its reveresed. Am i dumb lol?
not sure what you mean about the horn lining up? you cant get it 90 or its won't ride in the same slot with the new servo? I only have been using original servos so i have no aftermarket servo recommendation. And for the 2 speed you want drag brake in low gear and freewheel on high gear if your referring to the v3 WPL esc receiver.
@@RunThatRC referring to the v3 electronics. When in high gear drag brale is on, when in low gear it is off. I cant seem to get the servo to engage into low gear without the horn being the wrong way. Ive ordered the newer version of the 2 speed either way. Thanks i know its a bad explaination lol
Did you ever put metal links on a truck with the 2 speed? Annoying that the servo gets in the way, any solution? Seems like if I bend it it wont be long enough anymore
My solution would be to mount the gearbox higher up in the frame. It will require some cutting of the interior but not much. I had to do it to my c24 and mn model D90 (did not need interior trimming ) with wpl 2 speed.
370 I think would be the only direct fit. I have seen people tinker and mod these with 540 motors and brushless motors but it's a massive mod and not simply done.
been wanting to ask this.. w/c of the two has higher torque/climbing power? the 2 speed one on low gear setting? or the one with single speed geared motor&gearbox?
I have not upgraded any of my shocks on these. I use them as trail trucks and the flex works ok as is. Other people change the shocks to achieve more flex I believe. Sorry I'm no help with that mod.
Hey bud! Looking to get the 2-speed for my c24 also. How did you remove the plastic shaft from the part where it connects to the axles without breaking anything?
Me again🤣 so its dawned on me that my FS remote may have been lost in a move and I've just ordered the 2 speed... I only plan on useing it for low speed crawling so could I essentially tape the arm back to lock it in first gear?? Also what's a good tire for like 15$? Looking for somthing soft
It all depends might be the esc, battery or tx you use. Some Esc's you may need a bec for your servo. I have yet to have a twitchy servo. My buddy did but it was a dead battery. One cell went bad and his servo started twitching. Or it could also be a bad or defective servo?
The one that comes with au star transmitter. It comes with a receiver and a 20 or 30A something kinda esc. But it works fine except for the twitching 2 servos
I purchased mine on aliexpress and Ebay. Type wpl 2 speed and try to find a deal. The sellers I got it from dont have it for sale anymore unfortunately.
You have to use your own transmitter and receiver that has another 2 position channel or the WPL V2/V3 tx/rx kit. The RTR wpl does not have the ability to use the 2 speed.
What’s up bro, I just want to let you know that I Gia a two speed gearbox , but after driving my car three times, the servo on the gearbox started shifting from slow to fast speed on its own continuously. I don’t know why that happened. what are you thoughts? Also I notices that this two gearbox comes in two presentations. One with the little spring and one with out it. How can you get the one with out the spring? I don’t trust that one.
Maybe check to make sure you are not over working the servo by setting you endpoints or servo horn properly. Never had experience with the none spring gearbox so I dont know if they are worst or better.
nice video, i have one too for my MN 90... I upgraded all the electronics and now I'd like to upgrade links, gears and shaft but I find ridiculous the prices of these items. 50-60$ for a full metal kit... they'll pay 5$ to produce them :(
I agree with you. The metal parts are too expensive. As far as metal goes I would just get the metal ring and pinion gear that are around 10 bucks for the set and forget about all the other fancy things because it's all It really needs to be reliable. And maybe metal driveshafts for a little more worry free running. My B24zh runs great and it's only upgrade is 30a esc and 180 motor.
Not sure what your asking? You need help with the install of the gearbox or actually how to fix the motor if it breaks? Let me know and I'll try and help!
@RunThatRC huge difference with the outrunner I have a super modded c14 that has the gear reduction transmission with portals and its so smooth but speed is non existent with a 1100kv but I had overheating issues with brushed motor in the setup and batteries lasting like 5 mins now I can run it for 30+ mins without any issues with heat or battery drain

if you use that make sure its waterproof grease if you plan to run in water and just don't use as much of it if it is thick.

plastic but very durable. I run brushless in one and its over a year now without issues.
Also you can do 2 2 speeds there's a video on RUclips of it
sounds interesting to have dual gearboxes.
Can i change the normal speed 370 motor to High speed 370 motor with 52000rpm on this 2 speed gear?
you can sure try it out. I have a 4500kv brushless bolted to this 2 speed and its been good so far on my mn d90 with WPL parts for upgrades.
@@RunThatRC but how you found out the pinion fit to your brushless motor? The brushless motor shaft and pinion size must have been different from the original. It would be a hard work to procure and change the pinion gear on the brushless motor.
@@kennygo5053 I'm not using the stock pinion. I was lucky that the 10t pinion I had laying around worked for the job.
Thanks for the tip for the bending servo!
i have the same issue and maybe it will help :)
but i have another problem running the combo. my motor lagging when i drive - do you have any suggestion?
i'm running one of those cheap 30a escs but my friend got exactly the same problem running a way better hobbywing esc :(
Thanks!
I am not sure about what you are trying to describe.
I know much time has passed since posting this video, but would you mind telling how you have connected the gear box servo to the receiver? I have a Dumbo x6 Transmitter and the servo in channel 3 in my C44 only makes a about 60 degrees turn instead of 90.
Also thank you for posting all of the wpl videos, sometimes one can be lost without a good guide, since wpl (ans rbr/c ...) do not really care about that thing do much.
I haven't used a dumbo Rc setup on my wpls so not sure if your endpoint is adjustable on channel 3. You can try another channel
I just wanted to thank you for your advice.on the windows. I’ve ordered the two speed gear box with the 370 motor for an old wpl B14 I’m redoing.
When I hit the 3rd channel transmitter button, the servo moves 90 degrees and returns back to 0 degrees. How do I change that to where it stays in the 90 degree position?
What transmitter are you using?
@@RunThatRC I'm using a cheapo Turbo Racing 91803g-vt 3CH transmitter and receiver. I'm new to the hobby and I'm learning as much as I can.
Is there a way to program the 3rd channel to not act like a momentary switch? Is the controller a programmable one?
@@RunThatRC the controller has digital trim and dual rate adjustments. The instructions leave alot to be desired! I appreciate you taking the time to help Me out. Love your videos and enthusiasm.
i have this sadly SG micro servo wont last do i need to trim the servo endpoint?
im still running stock servo. All you have to do is mak sure its straight 90 when in low gear and no engagement when in high and mine have been pretty reliable.
Hi, I have the wpl 2 speed in my mn99. I also use the wpl metal drive shafts, however on the rear the drive shafts is too short and comes apart (Shaft does not stay in the holder). Which metal drive shafts do you use in your mn's with the wpl 2 speed? Thanks
I'm using the wpl ones and am not having and issue with them coming apart. I'm not sure whats going on there. Are the driveshafts the same length?
Thanks for your fast response! They are the same length. I think the issue is because I mounted the 2 speed gearbox at least 1 cm higher on the chassis, I maxed out on the length of the driveshafts. Grtz Gary
Just got my mn99 today, will this gearbox fit it?
it does fit it but since it's a 2 speed with another servo you would need a 3 channel transmitter and receiver to be able to switch gears.
@@RunThatRC thanks for the info
Please make a video of fixing moter
Are you talking about fixing the 370 motor? Not sure what your asking. Maybe you want a install video of the 2 speed? Let me know which one? I'll try and help you out
Man love your vids, you've helped me a ton with MN and now WPL! I have C34 (I know should've gotten the kit!) And I'm wondering if you have advice for making shocks less bouncy? Or a link to good replacements! Thanks so much!
you can try cutting the top tightly wound spring section and that should help but will lower the truck slightly. I run stock springs just spary oil in the shock every now and then and they perform better once you put some running time on them.
is there a metal housing for the 2speed trans?
I think there is a rbrc transmission that is higher clearance and metal housing. Not one from WPL themselves.
So did you just use a jst plug on the motor? I just got my 2 speed and noticed that it does come with wires and the esc I got has a jst plug. Kinda a dumb question just wondering.
Yes I used the included jst because the 30a Esc's I used have the jst installed already.
I just got 2 of them i ordered the new set. but i still got the old version. banggood needs some improving on inventory system ID.
But what you think is the best version? havent tested mine but old version with spring sounds little better dunno.
I am on the same boat. I ordered it also and it showed the new ones in the picture but they sent me the ones with springs. So unfortunately I have no experience with the none spring version. Hopefully I will receive one when I order more. Cross fingers. On the other hand i haven't had much issue with the spring version other than the flexible shift servo mount. There are several ways to solve that minor issue. And no stripped gears to report yet.
Anybody know what the numbers 370 etc means? Is it wattage or just a model number?
130, 180, 370 are motor can sizes.
Which one is better 2 speedgearbox?the version in this video or that comes without spring?
Not sure if your referring to the all metal vs this or are you reffing to the other plastic gearbox with no spring? This one in the vid with the spring has been pretty good and reliable for me. Haven't run all metal long enough to say and the plastic without spring I tried to get but was never able to get that style gearbox so no experience with that one unfortunately.
RunThatRC Well Thanks for your answer! Oh yes i forgot, how about the quality of a standard servo that comes from the package? Does it die easily?
Hi, can you please advise me on something, i seen that you work with a lot of wpl trucks, mine is still broking the diffs fromt or rear, once I’m forcing it a bit gone, i run 3 types of axels and they don’t survive more then 10 min....thanks
you might need to check your ring and pinion mesh while building it. It might be too loose and stripping gears.
@@RunThatRC hi, thanks for your reply, that it was what I think too but the last one, titanium one I bought it all ready build and same thing....I don’t know....thanks anyway.
I just bought a wpl b-16r and I wanna make it faster. How do I do that and what do I need to get? Do I need a different remote controller?
you would need the metal upgrades and hopefully they can handle more speed. These trucks where never meant to go fast. You can see how it goes but not my recommendation if you want speed. You would need so many upgrades and custom parts.
@RunThatRC is their anyway I can send you my RC and I would be willing to pay for anything you do to it ?
What size esc do you recamend if I am putting a 370 in my b24
The cheap little 30a esc I use in mine are good enough for it. The ones you find everywhere for about 10 bucks.
@@RunThatRC what type of radio and reciver do you use if you dont mind me asking
@@jasonsmithsrrcfun9259 I use a flysky gt3c and b. They have hacked firmware. Good radios for the price.
can i combine this 2speed gear box with stock wpl c24 board..
I don't believe the esc can handle it and you will not have a way to switch gears remotely.
Thanks for the vid. I'm trying to figure out what I'll need to do to add this to my RTR 24C I just picked up. The controller has no function to work the servo... and no where on the ece to plug in an additional servo.
Do I need to get a dif ece and controller to have this?
Thank you!
Yes unfortunately you are correct. You will need a 3 channel tx/rx to use the 2 speed on the fly. You can however shift it manually with a small screwdriver by moving the servo horn. I do recommend getting better electronics on it as it will increase the performance and make it more controllable and enjoyable.
@@RunThatRC Thank you. It's been a few days with this truck and it's a lot of fun. I've ordered a 3ch controller, and a new reciever.
I have the C24, will I need different drive shafts with the 2 speed? It's been tough to tell from vids.
What would you recommend, the 2 speed trans, or the upgraded motor and metal gear box?
Thanks again!

@@RunThatRC Thanks for all the info... If you don't mind, one more question, please. Regarding the two speed trans. Is the lower speed all torque, and the higher one for top speed? I'm not too concerned with speed, torque is what I'm after with this. That said, it'll be nice to blast it around quickly between fields though with the high speed.
Regardless, this two speed trans will make a huge improvement to performance, right?
Thanks!
@@christopherdonnelly6255 yes the 2 speed has a lower gearing so the 370 motor has tons of torque. Enough to break plastic parts if you get binded up. The second gear isn't much faster than the stock 180 motor gearbox combo. Enough for walking it around to the next crawl spot.
Broooooo! Have you see the low profile metal two speed by rbr/c?
just seen a pic of it yesterday. Wonder if banggood sells them.
Run That RC I hope to see a video about it soon!!!!!
Can you make a video of installing the 2 speed gear box on a c24 please?
Nice, 👍👍😎
Thanks 👍
When you do put more grease in the gearbox do you have to clean the gearbox first or do you just stuff the grease in with the wpl grease??
I just stuff marine grease in there with the grease that's already in there. Haven't had an issue yet.
Is there any difference in WPL 2 speed gearboxes for different cars that fit the 370 motor? I look for a slower gearbox for JJRC Q60 but there's no info about rpm on output shafts.
...or a motor that has less rpm but more torque =)
I know some companies make 2 speeds for these but the wpl official 2 speed are all the same. RBRC makes a metal 2 speed I believe and it has a lower low gear and a faster high gear. Very slightly but noticeable. Unfortunately I don't know the actual output rpm.
@@RunThatRC thanks for info.
I dont know of im stupid but i had a servo issue and have changed servos. (Fir the 2 speed) for some reason i cant seem to get the horn to line up and have the low gear with drag brake and high gear with high gear. Its reveresed. Am i dumb lol?
not sure what you mean about the horn lining up? you cant get it 90 or its won't ride in the same slot with the new servo? I only have been using original servos so i have no aftermarket servo recommendation. And for the 2 speed you want drag brake in low gear and freewheel on high gear if your referring to the v3 WPL esc receiver.
@@RunThatRC referring to the v3 electronics. When in high gear drag brale is on, when in low gear it is off. I cant seem to get the servo to engage into low gear without the horn being the wrong way. Ive ordered the newer version of the 2 speed either way. Thanks i know its a bad explaination lol
Did you ever put metal links on a truck with the 2 speed? Annoying that the servo gets in the way, any solution? Seems like if I bend it it wont be long enough anymore
My solution would be to mount the gearbox higher up in the frame. It will require some cutting of the interior but not much. I had to do it to my c24 and mn model D90 (did not need interior trimming ) with wpl 2 speed.
@@RunThatRC ooo that's a great idea, I'll have to see if ya had a video on that or try to see how I'd do it
Here's a vid I did on the C24 with lifted gearbox and body trimned.

Good day, will a bigger 540 motor fit on it?
370 I think would be the only direct fit. I have seen people tinker and mod these with 540 motors and brushless motors but it's a massive mod and not simply done.
been wanting to ask this.. w/c of the two has higher torque/climbing power? the 2 speed one on low gear setting? or the one with single speed geared motor&gearbox?
not sure which single speed gearbox your referring to. I do like the 2 speed personally. They work for my needs.
Hey I have an MN90 and I'm putting a 2 speed in with a brushless motor and I want more flex what do I do
I have not upgraded any of my shocks on these. I use them as trail trucks and the flex works ok as is. Other people change the shocks to achieve more flex I believe. Sorry I'm no help with that mod.
Hey bud! Looking to get the 2-speed for my c24 also. How did you remove the plastic shaft from the part where it connects to the axles without breaking anything?
I just carefully pry it with a small flat head screwdriver.
Me again🤣 so its dawned on me that my FS remote may have been lost in a move and I've just ordered the 2 speed... I only plan on useing it for low speed crawling so could I essentially tape the arm back to lock it in first gear?? Also what's a good tire for like 15$? Looking for somthing soft
The new WPL wheels and tires are nice. For the 2 speed you can just install the shift servo and just have it in first.
@@RunThatRC cool thanks for the reply
We can upgrade that motor?
if you please you can swap with similar sized motors. I put a 370 size brushless motor on one.
What esc do u use
Just using a cheap 30a esc.
gooooood video
Ya done good!! 👍🏻👍🏻😎
My original 2 Speed Gear broken , i change one Speed motor 380 more Power.
how many rpm, after gearbox...?
Sorry I never calculate those numbers. I think it goes 1mph in first or low gear if my memory serves me right.
RTR how do we solve twitching servos? Thank u
It all depends might be the esc, battery or tx you use. Some Esc's you may need a bec for your servo. I have yet to have a twitchy servo. My buddy did but it was a dead battery. One cell went bad and his servo started twitching. Or it could also be a bad or defective servo?
But i got 2 twitching servos. One is the steering and the other is the one that controls the 2 speed transmission
@@clydehampas1755 what esc are you using and radio gear?
The one that comes with au star transmitter. It comes with a receiver and a 20 or 30A something kinda esc. But it works fine except for the twitching 2 servos
Does this work with the stock esc??
you would need to upgrade your electronics unfortunately. Specially if you want your shift function to work.
RunThatRC can you give me the link to this product.
I purchased mine on aliexpress and Ebay. Type wpl 2 speed and try to find a deal. The sellers I got it from dont have it for sale anymore unfortunately.
Where does the servo wire go?
You have to use your own transmitter and receiver that has another 2 position channel or the WPL V2/V3 tx/rx kit. The RTR wpl does not have the ability to use the 2 speed.
can you put a 550 motor in it
I'm sure there are people that can figure that out with some crazy mods but to use the stock housing without mods 370 is max on the 2 speed gearbox.
is it ok to put GS Hobbywing Quicrun 40a ESC to 370 2speed transmission im running it to 2s 18650.
it will burn the ESC?
The brushed hobbywing 40a esc should be fine on 2s with the 370 2 speed transmission
RunThatRC how about 60A? is that ok?
@@benitisoy should be. I'm running a 60a xl5 esc on one of my b36 trucks
What’s up bro,
I just want to let you know that I Gia a two speed gearbox , but after driving my car three times, the servo on the gearbox started shifting from slow to fast speed on its own continuously. I don’t know why that happened. what are you thoughts?
Also I notices that this two gearbox comes in two presentations. One with the little spring and one with out it. How can you get the one with out the spring?
I don’t trust that one.
Maybe check to make sure you are not over working the servo by setting you endpoints or servo horn properly. Never had experience with the none spring gearbox so I dont know if they are worst or better.
Good yoob can it put in b24zh ???
This video is realy intresting love u!!!
can I put this engine on wpl c44km?
the C44KM I believe comes with this gearbox and motor from the factory.
Run That RC yes I belive too , but I want ask for this motor have three speeds or no?
i saw another wpl like this but its metal gears
yup metal kits are available for these.
is ok if i use a Hobbywing Quicrun 1040 40a esc to 370 2 speed 2s NiMH?
Yes that should work. I have a traxxas slash xl5 60a esc in one of my b36. It just takes patience to figure out where to mount it.
RunThatRC salamat dude asteeg ka sa RC
hope it will not burn the ESC 😊
@@benitisoy Haha I wish! I just been messing with rc since I was 14 so i picked up some skills lol.
@@benitisoy I think you will be fine. These 2 speed 370 motor gearbox can run with a 10a esc but not as smooth as higher amp rated esc.
That is the same stuff I use for all my vehicles
nice video, i have one too for my MN 90... I upgraded all the electronics and now I'd like to upgrade links, gears and shaft but I find ridiculous the prices of these items. 50-60$ for a full metal kit... they'll pay 5$ to produce them :(
I agree with you. The metal parts are too expensive. As far as metal goes I would just get the metal ring and pinion gear that are around 10 bucks for the set and forget about all the other fancy things because it's all It really needs to be reliable. And maybe metal driveshafts for a little more worry free running. My B24zh runs great and it's only upgrade is 30a esc and 180 motor.

1st tip is get rid of that junk motor and put a outrunner brushless in there
I have one with an inrunner but most mine are running stock motor on the 2 speed. An outrunner would make it a better slow crawler thats for sure.
@RunThatRC huge difference with the outrunner I have a super modded c14 that has the gear reduction transmission with portals and its so smooth but speed is non existent with a 1100kv but I had overheating issues with brushed motor in the setup and batteries lasting like 5 mins now I can run it for 30+ mins without any issues with heat or battery drain
