RE: Choosing an Appropriate Fast Electric Setup / NON-RTR
For nitro conversions you follow the same order as what is listed. Start with the hull size.
Use 6s or 8s LiPo
A motor from hobby king should be on the lower end of that range listed for kv selection.
I would choose either the 1200kv XL or the 1400kv L for 6s. For 8s choose a lower kv
ESC Find an ESC minimum 120A and 6s or 8s.
Start with the 40mm prop. You should be able to increase diameter in the upper 40's.
