Here are my motors:
HXT 2835 (380S) 2200kv inrunner
Walkera HM-22E-Z-36 3200kv inrunner
ICECold AKE623500FB 3500KV outrunner
Turnigy 2627 Brushless 3800kv outrunner
Hobbymate HB2622 5000KV outrunner
if you can show me how I can find the most efficient motor+prop combo, I could figure it out myself one day
