I pulling my hair out with gearing
I have a HB TCXX with a 2.0 ratio diff. I am using a Hobbywing 21.5 motor for 1/10 on road. I just want to know what is a good gear set for this car on a medium size track and have close to a 4.00 final drive ratio.Dont need any sarcasm just want a hood starting point or one that is proven to work with low motor temps. 48 pitch prefered. I have no timing in the motor.

I take it that your motor have a fixed timing since you said that you have no timing. If so put the motor on a motorlyser to find out what the timing is and people will be able to point you in the right direction.

Yes but your f/r toe settings might also affect top speed, acceleration, etc...

Thanks guys for the info that really helps me out a lot. The track is a outdoor track. Ya sorry about the hood starting point I meant good starting point but I figured most of you figured that out lol. Yes the motor does have a fixed endbell so no timing can be added.

64 tooth 48 pitch spur gear with a 32 tooth 48 pitch pinion gear will yield a 4.0 FDR with room in both direction to explore.

64t 48p might be hard to get.... 66t 48p from robinson is available everywhere, and will yield the same 4.0fdr with a 33t pinion....
