unsmooth drivetrain?

Postby Winner » Fri Dec 07, 2012 6:25 am

hey guys, there has always been a bit of friction in the drive train of my OTA R31, ever since i built it new. i figured it out when i was looking at a friends Xray T2 and i noticed how effortlessly it was to spin the wheels. what are some things i could look at or try to loosen it up and make it as smooth as my friends T2?

double check the tension of your belts, check the bearings, and check any moving parts for binding. if you're using plastic hexes, your wheels could be overtightened.

thanks for the help! the belts shouldn't be the problem as besides the main belt the other 2 are on their loosest settings. and the main is on just enough to keep the belt from jumping all over the place. i haven't thought about the hexes though. im running plastic hexes but i have a few sets of aluminum ones, i'll try that and see what happens. if that doesn't fix it then after the comp Sunday i'll take it all apart and see if i can pinpoint whats binding.

forgot to mention...unbolt the motor or unmesh the pinion and spur gear and see if it could just be your gear mesh.

thanks for the help! at the comp yesterday the screws holding the pulley on my oneway backed out so i decided to make sure the ones on the rear spool were n t backing out also, while i had them apart i decided to set the belts to their softest settings. that fixed a lot of it. still not as smooth as my friends T2 but just as smooth as another friends VDF. there's still some other things i want to try but its already much better then before. instead of running my throttle endpoints at 40% i had to go down to 30%

i dont normally use 100% unless the track is way wide with big sweepers. but by running a ESC with high amps i can set the endpoints low and not take a risk of overheating and burning up the ESC. plus its a lot of fun when you do get those occasional comps where there is a wide track with big sweepers to throw on some stickier tires and leave people in the dust :up:
