On the Kingcat, and some of the composite ARF planes, you have to heat up the flap that overlaps the surface and deflect the surface to it's maximum throw. Hold it in this position until it cools, and that shold keep them from binding.
We had a Kingcat that got damage to the elevators, when the heat from the engine caused the elevator to bind while giving down elevator commands. 8611 servos can really tear up your stab, because they go where you tell them to regardless of the fact that something is binding. Kingcat rudders are inboard, so maybe the thermal effects are a factor.

I dont really mind saying what i saw. My friend had to land gear up, loss of air pressure. The engine being angled the way it is caused his engine case to be really messed up (dented and scratched bad). I guess if you choose the one aircraft (with the thrust angle), since we are being discrete, i guess you better hope you dont have to land gear up.
The one aircraft has skin hinging on all flight surfaces, at least on the rudders this skin has binded no less than 3 thimes causing stripped gears in the servos. The hustler uses large robart control point hinges, very nice installation indeed.
This person who said that the modeler is the one to ensure a design is fit for flight is IMO way off. It doesnt matter if its a CRJ or a avistar, it is up to the manufacturer to design and supply an airworthy aircraft. ESPECIALLY IN THE DAY OF ARFS. I would never fly a real aircraft again if they told me i was the test rat that was going to make sure it was ok to fly. Just my opinion.
