Mine flys great
I put 6 min epoxy around the holes accidently when I was building and now I really have to push the wing down to fit. + I have a piece of foam mousepad athe the aft end of my fuel tank the helps everything fit tight.
I feel this plane is Good at 3-d but is a Great Flying airplane. I have other planes that will do any one trick great but this plane will do it all. Ass far as walls. Mine is so fast it sounds like somebody snaping a rug when it does it.
Waterfalls were really really tight with spolierons. Mine will ke but not loop.
