I've had one for over a year now, and never put it in a model until yesterday. (lol) They come highly recommended, but the set-up is a little strange. But, just follow the directions and you will be fine.
I put mine in a HobbyLobby LIL' Banchee (3D Prop model) and If the weather holds out... I'll give it a test run today. If it goes well... I plan on putting it in my HotSpot for next season.
I think Barry from KingTech is flying them.
