RE: KV Rating??
I'm lost. I've read all of this kv stuff and still don't understand. I have several power planes and just getting started in electric.I bought a foam pusher with a 400 brushed motor. Does not fly good,not enough power. Local hobby shop told me to buy a brushless in runner and they talked me into a 4200 Kv motor, 25 AMP speed control,and a 3 cell li po battery. The motor barely runs. WHATS WRONG I need HELP
