Flew mine today also, The thing flys great!!! No shakes at all with the 600 nitro landing gear!!! I'm even flying outside my comfort zone!!! AND no crashes!! I have a 6volt Rec. pack in it now and it seems really fast to my inputs, I didn't think it would be a noticeable diff.
Flew the sh%%%T out of my Screamer too. WAY outside my comfort zone!!!
