I'm starting to wonder how you managed to get your CX2 to fly that high with the training gear stuck to the bottom?
Reason I say this, I recently tried connecting a MINIATURE Cam to the bottom of my CX2, and the bird found it difficult lifting off the ground. Flying, changing altitude or direction, and the CX2 would slowly descend down to the ground, as the extra weight was just too much for it!
I am also thinking about the Extreme 180 motors - but it would now be pointless, as Im also condidering a new Heli anyway, so will strap my Cam to that instead
