I have a hanger 9 cap 232 that came out of the box with a warped wing. Needed lotsa aileron trim. Pulled the covering off the bottom and many of the ribs were barely glued, well if they were they weren't any more. Also, with the elevator servo's in the back, i needed a pound of nose weight, so now running single servo up front and pushrod. The plane is still a dog though. Good luck
