CRT Conversion Questions

[vbxt]

Hey,


Just to chime in about my X1 CRT build. I am running the MMM 2200kv combo, stock 62t spur with a 14t pinion, and 4S 5000 mah Zippy Flightmax 25c batteries. I ran this combo at the track last Saturday for hours without a problem.

The Zippy's seem to perform very well in my limited testing. I didn't bother to take any temps because everything felt to be under 100 degress to my touch.

I have also tried a 13t pinion, but I had problems with the mesh. It would clack as it was braking. It seems that pinions with higher tooth counts mesh better. I would really like to try a 16 tooth pinion with this combo. I've found that with higher tooth counts I tend to get better acceleration because the torque does not hit the wheels so hard causing spin (thus less acceleration).

I will say that if unlimited traction were available, lower gearing would produce faster acceleration, but in the real world where I can spin my tires at will even on pavement, higher gearing gives me better acceleration.
