I am using some cheap china stuff in mine a 35 amp water cooled esc and a 3300 KV motor it was 100.00 or so shipped to my door.
I am waiting for it to arrive to test it out... what you should go by is the widow maker 22 from pro boat it has a 35amp esc and a 2900kv motor... I also ordered the widow makers prop as it's only 35.8mm and smaller than a CF40 prop.
Go by the widdow makers specs if you intend to run 1 battery pack or a 2s lipo like i am...If you plan on going 3s lipo you will need a much lower KV motor.
