- How to get Inside the RIPSAW drift tank gearbox, how it works, possible motor upgrade is what I was thinking but I could not find a faster 390 motor and from the look of the motors com and brushes it looked like it handled the 3S lipo battery fine so I just decided to leave the stock motor in it.

I dont know if you are already figuring this out or not. It is a double differential steering mechanism. A realistic mechanism of how the real tank works.
So to pivot turning in place it use its small motor to turn the outer gear of the diff, to going straight use the large motor turning the middle gear, and to turn using the small motor to interupt the diff so that one side will become slower vice versa. I never thought this cheap RC have such complex realistic mechanism. It is awesome!
Yep, why I contacted kyosho and said they should make there kyosho blizzard work this way but they never listen!! This drives so good almost like driving a normal rc car! Thanks for watching.
I have this tank. I bought it as a toy to play with some 3.75” action figures with the kids. I’m impressed with how freaking smart you and all the RC guys are in upgrading electronics, motors, etc. I want to do some of the graphite maintenance on the tracks from your other video. The only other “Mod” I want to do is cosmetic. This tank needs a good quality woodland camo paint job!!! Maybe I’ll disassemble the main parts and get the spray paint out.
Thanks for the videos!!!!
Thanks so much! these little tanks are so much fun!!
That gearbox looks great
yes it's a cool design. Thank you
I think am going to get one , with all your vids and mods you have convinced me 👍 great video bro 👍 👌
You should! These things are fun as heck! 😁👍
Nice, in-depth look Steve! Pretty impressive!👍😊
Thanks! 👍
Cool, thanks for looking in there for us, I'm not smart enough to make sense of the gearbox on these but now at least I have a reference for someone who is
👍Your welcome, thanks for watching.
Really interesting! It looks like a well engineered and built tank, it's always nice to take things apart and see how they work.
It really is! Thanks for watching.
Excellent disassembly and great explanations, good info.
Thank you kindly!👍
@@ShenRC 😊👍
Thats cool lots of gears to keep track of i like they use the same screws on the whole tank😀💯
Yes that is nice about the screws all the same, To be honest this gearbox is way better than the blizzard kyosho should copy this design it drives straight all the time and drive smoother and turns way better also. Thank you
Cool info,pretty cool the way it operates
Thanks it's a cool design for sure!
Thank You Sir!
To be honest, your video gave me reassurance in regards to buying this for my son!!
10 Star Video Sir :)
I love these things they are so much fun!! Glad I helped you out, Thanks for watching I have many more videos of these tanks.
So cool. Thanks for sharing!
Thanks for watching!
Another fantastic and interesting video my friend🇬🇧👍😎👊😊🤟
Glad you enjoyed it! Thanks 👍
Nice video. Really liked your explanation of how the gearbox works. It's great in the way the steering and drive functions are separated yet together. This means the tank tracks dead straight so the fact that the stock Tx has no trim function really doesn't matter. Of course with your modified set up you can use a better transmitter anyway. I can relate to the grease getting all over your fingers - I had the same experience when I pulled mine apart :).
Thanks, yes this set up is very nice I wish kyosho made this style gearbox for the blizzard.😁 LOL! greasy hands and RC doesn't get any better than that! LOL!! Thanks for watching 👍
Very interesting design looks like you can change the steering motor for a servo, good video
Hi I don't think you can use a servo it turns by that smaller motors gears riding and turning those two big diff type gears. Thanks for watching.👍
Great Video 👌, Diff System is very advanced, saw a similar System on a R/C Truck from Radio Shack back in the mid '90s... only it was a 6 wheeled Dump Truck with conventional steering on the front axle. Believe it or not, they used the Diff System to Control the Steering instead of a Servo, Diff allowed steering motor to turn after drag link reached it's limit and prevented steering motor from burning out.
I admit, your Ripsaw has a more advanced system than Kyosho Blizzards... But the Motors are actually the least Expensive part of both Ripsaw and Blizzard Drive Lines... Kyosho Blizzard Line is designed to be abused and easily modified, Ripsaw isn't... unless (of course) someone has Your Skills!🏁
Hopefully kyosho will see this video I sent them and asked about them using this type of gearbox in the blizzard if they can copy it and make it better. 👍
All is good bro.
Thanks JD!
I upgraded my blizzard right from the start. Its really fast and I added smoke and sound but took them back out. White smoke on white snow just doesn't work. The sound system kept restarting over and over as well as sounded tinny. I do like all the leds I added. I just ordered the ripsaw and will be adding more LED lights. Oh, also, I finally found a driver to fit my Blizzard. That took a while. I seen someone used a 4in figure in the ripsaw, but thats too small. Needs to be 5 inch.
Cool! 🎄Merry Christmas!
Mine broke down this afternoon. I live near Houston and it was hot in the parking lot where I was running it. I suspect the heat deforms the plastic gears. I have to take mine apart tonight to see if I can fix the warped steering gear. I’ll be rewinding this video a lot!!!
O man that's not good. let me know what you find. Thanks for watching.
@@ShenRC, I just fixed it. Your videos were a huge help, thank you. A main plastic part just melted into an adjoining plastic ring and froze the whole tank. I suspect it was from zero grease being applied to those parts at the factory. Either that or it was just a defective part.
It took 2 hrs and 45 minutes to tear down, clean, sand, re-lube and reassemble the tank. I wet sanded those rough plastic gear parts And basically polished them until they were smooth as glass. Then I coated everything with Tamiya Cerra Grease which is made for metal and plastic.
The tank runs smoother and faster now. Got me to thinking….if a guy really wanted speed out of one of these, every moving part should be wet sanded, polished, and greased until everything rolls freely.
I think the motor got a little damaged by being stalled. It smells burnt. Thanks for the video! 😊
@@MusicStudent1 Cool glad you got it working!! Thanks for watching.
Awesome video dude! I was super curious how the transmission worked with the second motor on top
You and me both! it's a better design by far than the kyosho blizzards that's for sure! Thank you
Great video! And I want to ask -what type of grease did you put into gearbox? My other RCs have metal parts in gearbox, so I used to put some unversal grease-motor oil mix with good anti-wear results.
Hi these tanks come with a lot of grease in the gearboxes. It looks like that superlube grease to me but any plastic safe grease will also be good to use. Thanks for watching.
Hey Shen, great teardown, havent truly pushed this baby yet, but so far im noticing that it turns on a dime much faster clockwise then anti clockwise. almost like something is binding or slowing it down when turning, also when crawling in tight or rough terrain situations the turning motor doesnt seem to have enough torque. Any thoughts on an upgraded steering motor?
that's weird but I do think they turn faster one direction. If you use normal radio and hobby esc's they control much smoother and better. Thanks for watching.
Great you are great! THANK you
Thank you too!
Yes, i thought of open myself, cool you did :) WhatsApp Kind of Speedcontroler Do you Use? Different for each Motor? Wich on offen Switch to Use? Got mine without electric want to Use S2 Akku. Thanks a Lot! Glad Not to be allone on this Planet like Things like that =)) CU
@@erikarolf2504 Hi thank you I have many videos on this but make sure you look through them I suggest the larger 1060 type esc's for this for the best control and performance.
If I wanted more torque and less speed, is there a change I could make to the motor or gears for this tank? Thx
Hi you would have to find a lower RPM motor and it should go slower and have more power, 380 390 size.. should be able to find on these are pretty high rpm for the stock motor... I bet a tank motor will do just what you want. Thanks for watching.
That’s very interesting to see how it works inside 🙂👍🏼 nice share bud! Love that rpm checker too 💯how much does one of those cost?
Thanks bud, that is a sweet tool to own and cheap like 14 bucks! search digital tachometer on amazon
@@ShenRC cool beans, I will check it out. Thanks Steve 🤜🏻🤛🏼
Wish they had metal gear upgrades for this, and brass or steel lower wheels for crawling
Yeah I asked them about making metal gears but no luck. Thanks for watching.
Great video, maybe too advanced for me. I've heard a few people have steering but no drive so it's most likely the 390 motor is kaput? I fancy one of these just to run with a friends 1/16 Tamiya tank!
Thanks for watching, I really enjoy these tanks I have a lot of mod and upgrade videos and cool running videos of them they are a BLAST!
If it's a 390, maybe the MN86k red-can motor would be an upgrade? Above that I imaging only a brushless would be an upgrade.
Hi I am not sure this ones fast I tested the RPM's of it but I also have another video that I show how to advance the motors timing to make it faster. Thanks for watching.
I Need only zu Upgrade the main Motor to brushlessmotor and Add an brushed ESC for the Custom PWM reseiver
Hi you can do that with this tank👍
Hello there I’m a little late to the party I just recently acquired an rc tank but it not sg or eachine brand out of the box it does 18kmh I’m just wondering is it ok to have a bent spool wheel or sprocket mine drives fine will it be a concern I’m new to tanks lol i am thinking of buying the sg and eachine tanks as well
Hi yes the rear drive sprockets do wiggle side to side they are not perfectly straight. Thanks for watching.
@@ShenRC thanks man and no prob you vids are very helpful and entertaining
i have a sg1203 aswell, i am wondering, i feel that (when i take the tracks off) the drive wheel has alot of play on it, is that with all of them or should i check mine for tolorances???
Hi yes the rear sprocket that powers the tracks does have a lot of play in them.. Just check the screw that holds them on it comes lose sometimes. Thanks for watching.
@@ShenRC thanks for the reply, did like your vids. i've already took mine apart, and noticed the locking piece of plastic on the end of the axle shaft, should fit in a slot on the engine cover. but mine was turned 90 degree. I've put it back correctly and now the play is much much better!
@@renatakoningova Cool! and yes that cold take out some of the slop in it for sure!👍
For toy grade RC that is one helluva clever, complex gearbox. I have no interest in owning one, more interested in scale speed 1/16 tank stuff but thought about buying one just so that I can marvel at that gearbox!
Hi yes it is cool and works great, they sure are fun! Thanks for watching.
I’m really surprised they went with a double differential transmission instead of just using one motor per track
I am glad they did this drives and controls smoother than any twin motor tracked tank I ever had. It's nice! Thanks for watching.
@Shen RC my son has a tank that has the dual motor setup and after using this buzzsaw for half an hour it's lightyears ahead of that setup. The steering is so precise. It's hard to really explain until you try it but it just behaves like a normal rc car. As others have said its An amazing gearbox on this level of rc vehicle
Hello , my bro ,the sg-1204 is released , i think u will get one!!
Yeah I seen those. Thanks 👍
yup 24k+ is a fast 390. really clever how they made the little 130 motor control speed of both tracks so nicely and proportional like it does!
It works awesome I sent my video to kyosho and let them know how good it works and that they should make this style gearbox for the blizzard. 👍
@@ShenRC yup, larger with room for a 550 size motor would rock!
Bro, the motot gear is 48p right??
I think so.
So you can run this little guy in 3S?
Only if you swap out the electronic with normal rc components but even if you run 3s you will put a lot of stress on it and have much more chance for something to break on it.
4:34 gears look plastic but they have a lot of grease in there
Yea it only has 2 metal gears inside it wish it was full metal like how they show on the box..but we know how thee companies always BS about stuff.. Thanks bud,
Cool test with the RPM meter woud have been nice to know the steering motor RPM. I put a brushless 5000KV 2845 motor in mine and run it on 2S lipo so about 37000 RPM. I wonder what woud happen if i put in 3S with 55500 RPM :D
Thanks, Also 3s only one way to find out! 😁
@@ShenRC Well... stay tuned I'll find out soon haha. If everything works out I plan to add a Smoke/Sound/light module and a BB gun :D
@@ShenRC Did a Speed test on 2S: 8,7 mph so already faster then your mod :D
@@mixtape8992 Cool I have to re gps mine the one I was using was way off.
Brushless in that size... 2S would kook & book. 3S would prob thrash the gearbox.
Hi you don't need brushless in these things they are pretty good out of the box. Thanks for looking.
I dropped a 2s lipo in mine without changing anything 7.4 v lipo
yeah it will work but will make the electronics run much hotter and can cause them to fail. Thanks for watching.
i'll never drive mine enough to tear it up haha
Yea you won't ever wear yours down.
looks very complex for a toy
It has a better design gearbox than my $300.00 plus kyosho blizzard!
Don't bother making it faster - install FPV. I'm going to put a 2 cell 18650 in the rear and maybe some weights up front along with a FPV camera and battery in the cockpit.
😁 To late I already made them faster. FPV will be cool with this thing... Thanks for watching.
