run time question

[BrianG]

^ +1. Yep. Higeher voltage, lower kv (keep total rpm ~35k-40k), gear down, lighten the weight (tires are a good way to do this), higher capacity (mah) batteries, and be easy on the throttle (no super fast starts as that pulls a lot of current). Might help to set punch control higher on the ESC to tame those high current bursts, but might also mess with your throttle timing when you want a high burst (like before a jump).
