Hmmm... You're the third or fourth guy I've seen make that comment. Those quad flaps are the main reason I bought this thing.
Well considering it only lasted a day or so before the stab came apart that is probably not that unreasonable. I played with it a couple of times, did the harrier, 0 ground speed flight in a light wind that sort of thing. I guess it was nice but it never got my blood going. What I did the most is just fly the thing at full throttle and rip it around the sky just as fast as I could get it. I had a bunch of fun doing that.
I would like some sort of flap however and I was just thinking of using the flaperon mix with the full span version this time..
