Questions?? Need Gearing Suggestions

I keep burning through gears like nothing and I need to find a better gearing setup for my TT-01. The CastleCreations setup keeps crushing spur gears (MY MESH IS PERFECT SO DONT EVEN GO THERE ). I was running a 61 spur and 19t pinion but I think I need a better setup. I have here a 19t and 18t pinion and a 55t and a 58t spur. I would like to buy the least amount of new gears so if you can think of a setup that incorporates one of these that would be great. Btw these are 48 pitch and I run touring

what motor are you running

are you using the plastic motor mount
does the car have a top deck


it sounds to me like you are getting a fair amount of chassis flex which is affecting the gear mesh

those cars dont work well with much over a silver can in stock form they are flexy flyers

Its a castle creations CM-36 4600kV. Yes, it is the plastic motor mount and yes, it has a top deck

The chassis flex would explain this:

Would a graphite fiber chassis keep it from flexing

Is it the chassis or the motor mount causing it? A powerful motor could cause the motor mount to flex or squirm about somewhat through a mix of tourque and heat, which would give un-even wear on the spur. I would start by eliminating that first, a alloy motor mount is going to be cheeper than a carbon chassis and something you would need to upgrade anyway even if you went carbon.

Not sure. I'll probably try a $13 aluminum motor mount before I have to yet again disassemble the whole car to convert it to a $120 graphite chassis
