RE: .21 Zippkit ready to go
I do have the zip 440 ,the problem lies in the start. she likes to die on take offs. I had a 3 blade before, she never bite very good . I wanted to go small on the prop. Then work my way up. I had a X 438 in the video. But I have the AB parabolic pipe on now, lets see what I come up with, just looking for a clean safe run. I better stay with the X 438 2 blade
