hello
i had the same thing with a brand new Cap 232. I had one flawless maiden flight then on the second flight the airleron connection worked its way out a bit. I lost airleron control in the middle of a stall turn then i came back on a spun the plane with no imput from me. I couldn't figure if it was interference or something else. The connection was intermitted so i would use the airerlon to level it but it would respond a few seconds later. I managed to land it downwind with no damage at all.
When on the ground it was still messed and we tried swapping transmitter cyrstals (we can do that in canada) into a different transmitter. It didn't solve the problem. But then i saw the aileron connector backed out more than the others. When i pushed it back in they were fine. I fixed it with a few elastics around the whole reciever and connectors and it has been fine since.
