i think that 40t spur is gonna be perfect actually. i ordered the 36t and i think that is gonna be too small but i will try and see. i just dont want my esc overheating cuz its geared to high. and with a 36/18 it is just insane speed. i actually have a 16t, 17t, and 18t pinion gear so i can play around a bit with those but i think like a 40/16 is gonna be the ideal setup on 10s. it will be fast. probably in the 50mph range when its actually on the street. i am heading to the machine shop in like an hour and gonna get the gear cut. i am milling out the center are 6mm so that the gear will sit like the stock gear and shed some weight. i am just gonna save the CAD files so then when i get that 40t spur it will be a quick fix. the 48t is way too big. in fact, i bought a 48t gear already remember? that 48t FG gear. i thought it would work but it was WAAAAY too big. go with that 40t and it will be perfect. or if you want Kaz, i will order 2 of them right now, get them machined and hardened, and you can just pay me the actually cost of everything. the gear is $20 if i recall and i will know today how much to CNC will cost and hardening i will have to find out. i dont think it would be more than $50 for everything though. of course, i have already paid for the machinists time for drawing and stuff so you would only actually be paying for machining time. let me know

also SuicideNeil,
what do you think is gonna be the best gear ratio on these things? you seem to know alot about that stuff. keep in mind the largest spur gear is 40t. 10s, 750kv Neu. what do you think as far as pinion?

if the motor is torquey enough it might not even matter what gearing we run...within reason of course. i was just hoping that with the 36t my temps would be ok still cuz i figured this motor has enough torque that it would be fine. i am gonna order that 40t spur just to be safe though.

btw, i just ran the rc-calc. and with a 40/16 gearing on 10s, 750kv and 7" tire it comes out at 53mph. with 36/16 gearing it is 59mph. 36/18 = 67mph. i was gonna run this gearing if temps are ok. 36/18. 2 to 1 ratio. could be crazy.
