I have the best AA ever. It is stock out of the box. It flies great with the trim and tail flaps neutral. I can make left and right turns at full throttle with no downward spiral. (it climbs on a full charge) It will do more laps in my basement than any other AA I have flown. It has no delay in the remote control like some I have tried. I returned two AA because they flew like crap. Mine is a 06, green, yellow, channel b with the corner cut box. I tried changing the cg and moving the flaps but it didn't make it better. I would like to see a poll about how many people took their AA back to the store because it sucked. I think there are few as good as mine. Maybe I should sell it on e-bay for $75. lol
