I am trying to duplicate the rediculous speed I saw on youtube Hoffman magnetics Great Planes L-39. It's a beast. Does anyone with edf experience know if the thing will fly with a 4s 2200? Too heavy? The man. told me they use the2200 Ma but on a different, slightly larger jet. Can I use a 13, or 1500 Ma 4s?
any help from you guys would be greatly appreciated
I have the mighty mite motor, a castle 45 and the stock fan unit(i am told it'll hold together to 50,000 rpm)

I am an experienced heli flier, and have some airplane exp, but only 1 edf jet, a F-4 mini from Hobby-lobby.Small and quick on 3s 1300
