I had one of these 2 years back. Flew great. Didn't experience the problem you've had although I've had a couple of other models with horizontal stab weakness. I thought the undercarriage fixing was extremely bad. Their are no real solid mount points for the undercarriage straps. One poor landing and the undercarriage wire can either get push through the underside of the wing or will rotate and the wheel will pierce the underside of the wing. I never buy planes with the undercarriage mounted on the wing anymore.
