that type end cap more difficult to pry loose, even without a tach, first thing to do is find the brushes neutral timing point. listen to the motor's song with forward and reverse polarity, when its the same speed in both directions, mark the end cap and motor can with dots. to advance timing rotate brushed into aka opposite the desired shaft rotation. it is usually safe to go 15 to 25 degrees advanced, they spin like mad and get hot after 30 degrees especially, so I usually don't push that far.
if the motor started with neutral timed brushes, usually the case for a motor being spun clockwise (aka reverse rotation), Steve just showed you exactly right "how to" in this video, my eyeballs are telling me he set it right near 25 degrees advanced.
tread rpm ballpark... if the track length is 24", then tank speed increased an extra 80 feet per minute. 4.32 mph becomes 5.23 mph (just ballpark math @ 24" track length) with the motor timing gain.. so you lose a little speed in reverse, oh well! over 20% speed increase.
you might not want to try feeding it 3S after doing this, there's a possibility of cooking it or the motor throwing its own armature wires for spinning 45k as it screams "help me!". 390 motors are cheap enough to replace if you want try it, whole drive isn't too expensive if you do somehow melt down the gearbox. cool video!
😀👍Great info Model Nutty! If you did this to a 390 motor in a normal RC it would really get a lot faster.
@@ShenRC oh heck yeah, do it to a 390 for normal CCW rotation and replace a 380 in a Grasshopper it'll flat scoot.
Somebody told me that more rpms is less torque so for a crawler this mod will not help, what do you think?
@@carloshnunez Hi all depends if it's gear ratio is super low a higher RPM motor can work very well.
Great bench work Steve, love that timer!! L#29
yes it's very useful. Thanks 👍
I have been watching you for a little while now. You are a Beast, you know exactly what you're doing. Now I want to get one of thebecause. I have you to guide me through all the things to upgrade it. Thank you, you're a blessing.
Awesome have fun, thanks for watching.
Excellent, very good upgrade and great explanations.
Many thanks!👍👍
@@ShenRC 😊👍
Great info on motor timing there Steve, and nice job showing the differences!
👍😊
Loved the intro!😂
Congrats on 10k my friend!
He he yea it was fun! glad you liked it. Thanks 👍
Great intro Bro!! Congrats 10k
Thanks so much!!😀👍
Beast mode Shen
👍😀👍 Thanks!
Cool mod,great video,have a great weekend.
Thanks, you too!
Steve have u looked into rehab for tankitis? Lmao 🤣 nice to see you are always looking to make things harder, better, faster and stronger!🛠🛠 👍👌 nice work once again.
😀LOL!! 😀 Yes doctor on his way now! 👍Thanks for the comment.
@@ShenRC lol rite on Steve🤣!👍 i posted a short vid on my gen 8 slider mod if u r interested.
Great trick and demo!
Thanks man. 👍
Congratz on 10k subs! Awesome upgrade! now it looks fun! How much do you sell the Shen RC versions for? LOL!
Thanks so much. Fully tweaked Shen RC versions....O no people may want them or want to send in motors to get tweaked! LOL!!
Great info man thanks for sharing! 🍻👊🙂
No problem 👍
Those old ass vice grips have been through hell
Yes for sure they been around for a long time! Thanks for watching.👍
Nice bro 👍👍😃
Thank you so much 😀
lmao that intro though!!!
😀👍 It was funny! LOL!!
Great video good to know I might have to do this 😜 but not before upgrading the electrics
it might be OK being advanced 15-20 degrees, current pull goes up lots more usually after 20 degrees. also usually peak rpm at 37 degrees plus, before the torque face plants. its all pretty typical with DC brushed motors.
HI you may as well try it with the stock set up first it may work... if it burns out the stock boards then go to the upgrade method. Thanks for watching.
@@ShenRC with stock board I'd dare 15 to 20 degrees anyway.
@@modelnutty6503 I will give it a try 🤞
I will try this on my remaining brushed SG 😎 thanks for the video 👍🏼
Cool it makes them run at a perfect speed...if you did not see my speed drag race video of it racing a stock motor one check it out. Thanks
@@ShenRC Yeah, it is a great improvement! Next, I will have to race my Brushless 1203 vs the Advance Timed 1203 😎
@@jamesreben1761 You can go a bit further on the timing I got one to go to 42.000 RPM on the stock battery voltage but that's pushing it.
@@ShenRC 🤟🏼
so great: LET THERE BE SPEED!!
😁👍 O yea!! Thanks for looking.
Looks like you need to make a race video now. Brushless against brushed. Nice mod my man.
Hi thank you, 👍
Looks like its very close to 3s speed. Not as punchy as 3s of course but speed wise close. Nice job!
O it's punchy I have lead weights in the front so it don't lift like when I tested my 3s one that had nothing in it... I will have to GPS test it to see I know how fast 3s is from my gps test run..also going to drag race with a stock motor one and see.👍👍Thanks for watching.
@@ShenRC yeah it's definitely punchy I just meant not quite as much as 3s would be but it's definitely a great improvement over stock! Can't wait to see the test!
@@GussCustomCreations GOOD news! Just did some drag racing and GPS testing ...lets just say..more motors getting timed now! 😀👍It has more power than the stock motor it plus a wheelie and then gets thrown crooked from it. video soon!
You should try a Traxxas 380 titan motor. It maybe slightly shorter but may be a faster motor or a brushless 2845 system.
Hi I believe this 390 is faster than the titan 380 after timing I got it revving 35+ thousand RPMS, this is plenty fast for these tanks you don't need to go brushless with these things. 😁👍Thank you for watching.
Wait, so the tank runs on a single motor and uses another motor for steering, like some sort of powered differential? Interesting. Most manufacturers would just use two motors and two gearboxes.
Yes it's pretty neat. Thanks
Get ready for the next video, Motor explodes on camera haha
"look what I can do with 3S!" hehe
😜 BOOM!
What paint did you use to make that black glitter tank?
Hi that was my custom airbrushed tank I used all metal flake and sprayed and dusted it on and cleared coated it.. it's cool looking. Thanks for watching.
@@ShenRC yah damn cool looking! Can you send me links to the paints/flakes you used? I have a compressor but what airbrush attachment do I need for something like that? I painted some stuff and it always looked bad, how did you prepare the body? Maybe you can make a video on that I'm already subed :)
@@mixtape8992 Hi the bodies must be clean of oils use windex on them to degrease them...I think I show me airbrushing my green on in the build video I forgot, I got sparkle kit on amazon with many colors in the kit but when you use these you need to use the water base clear gloss coat so it don't melt the plastic flakes.
390モーターが12vで動かすものらしいのでバッテリーを11Vのものに交換したらパワーアップしないだろうか？
Hi I do run some of my other tanks on a 3S lipo. Thanks for looking.
Pretty cool mod, may have to try this timing on a spare motor i have laying around to see if it makes a difference
Hi bud, if you did this to a normal motor like in the cars you run you would notice them go much faster than in a tank.. try it out. 👍
What size lipo and mah fits in the stock tray?
Hi I cut that center slot divider out of mine and I am running 2200 size that fit 1/16/ 1/18 scale trucks. Thanks for watching.
@@ShenRC Thank you, is that 2s or 3s?
@@blake_0007 Hi 2s
Nice mod, did you lose torque?
Hi you can see in my new video I posted up, I drag raced the stock one against mean green. In a tank with super low gear ratio it don't matter it actually flips up even more violent than the stock one.👍
Turbo tank.
😀👍O yea! Thanks for watching.
