It flew really good right outta the box! DX7 bound up no problem and it only needed a couple clicks for trim. First flight was at neutral CG then I moved the 12c pack back to where the velcro ends and found the magic spot! 6% rudder mix and this thing harrier rolls easily. First respectable one I have had flying anything! Got about 220* in a rolling harrier circle before I blew it. Ditch the little rubber spinner as it is just dead wieght and lightens the nose up a tad.

Durable this thing is. I pegged it in inverted,and just about every other angle in a solid 1.5 hr indoor session. I know for a fact the Parkzone lipos for the sukhoi and ember/vapors are not adequate in C rating. My 120mAh batteries lasted all of 4 minutes and they did not have the burst or constant C rating the E-flight ones do. Big difference in performance too. Go full throttle with those and the ESC will chime through the motor its pulsing objections to not receiving enough juice.

All in all, it is a good little fun plane to toss around the gym! I am havin' some fun!
