xxx-t gearing
alright i have a xxx-t that i recently got and thru my hitec esc in and bought a 13t double team orion motor for it. i was wondering what the best gearing would be for a short track with only one decent straight but has alot of tight turns and jumps outa the turns. let me know thanks

RE: xxx-t gearing
you probably want more acceleration if there is only one straight away.
i would say like a lower pinion than stock if you want more acceleration.
if you want more top end go like 2-3 teeth up on the pinion.
dont change the spur though because i hear that it can overstress your motor.

RE: xxx-t gearing
What size spur are you useing? 86?
Start low and work your way up till you like the speed/handleing. Maybe start with a 13-15 tooth pinion.
Smaller pinion = quicker acceleration
bigger pinion = higher topspeed+ slower accel.

RE: xxx-t gearing
wait what some people are saying start at 13 and others 20? that dosnt make sense. i have a 14 on there now but dont like the acceleration. i'm new to gearing electrics been into nitro for the longest time but havnt dealt with electrics in a while. it is the stock spur gear bby the way

RE: xxx-t gearing
On my home short track I like the 86 spur gear (Red) with 17 pinion (XX-t sport 2 Tranny). This is with a stock motor p2k2 pro. The track is a very hard clay surface. about 80/30 feet. [link=http://www.mhorrc.com]see pics here[/link]
This is probably a little to much bottom end for a 13 double mod. So, with the red spur gear I would try 2-3 teeth greater on the pinion.
smaller pinion = more acceleration decreased top end
smaller spurr = more top end decreased acceleration
