Update: Maiden the F15 w/ EDF unit u sent. All went we'll. The only thing I did encounter was that the motor cut off twice in flight just for a split second. Watch video of 2nd flight (between 2:36 - 2:43 time on video, actually right at 2:40 time) close to the end of video.
I'm not too concerned at this point.....or should I be :roll: I've had so far five flights but brainstorming what it could be ?
