Hey O.S.
#1
I recently made a truggy from a T-maxx and the HCR mutnat maxx kit.... I had to make a new center diff brace and Upper chassis so I could put a larger Spur gear on it....I'm now in the realm of super low gearing and finding out alot of engines made for off road don't rev as high as I'd like them to....yes I have changed the CB and tried 12/13/14t the 12 just seems to work the best but I need more RPMs...I'm using a VZ-b (not the V-spec) right now and was looking at On-Road .21 mills....are there ANY reasons why I shouldn't do this?? I'm mostly concerned w/ Bearings, I was told alot of On road mills use ceramic bearings.......

I have 2 RG mills I modded but they don't seem to like the higher RPM range it has now and eats Conrod bushings....any suggestions on another Conrod that fits the RG......as it is now I check the one engine every 2-3 tanks to be sure it's not eating the lil bushing.....actually they are spinning in the conrod and blocking the lil hole on the bottom...I'm sure w/ enough time they would grenade like that if I don't catch em
