Well, judging by the bad remarks, I'd say I'm perfectly happy with my aero ace. Funny, I almost picked up one of these things today, but decided an Ace was as good as anything with some mods, so back to the operating table! I've had 3 Aces with no problems ever unless you count a sticky motor. I'm always a bit leery about tiny planes, and it seems I may have been correct this time. A good plane is relative to what the pilot has flown before.....
