I use to have a Piper Club.. 3 channel... I got it doing backflips in 3 days I can get the hang no doubt... Ive done it with all R/C's people just say I have the gift... Rc shops tell me I could go pro with easie... So... Will the Apprentice 15e fly upside down? OR do yall have better ideas? 5 channel 6 channel ect?
