Crazy2602-from what we have learn so far is that yes stock setup can be flown on six. It's pretty fast i believe. BUT there was only one were the stock fan has blown-up. About retracts you will most likly spend more time tinkering with it then any part. I did split mine up to 3 channels and it worked great. THEN after that servos started to give up
. O well over all this thing is a great in the SKY! If you feel that you have skipped any of the pages feel free to ask anyone of us. We have a REALLY GREAT GROUP HERE!
