B&B Specialties makes a mounting system to strengthen with music wire.

The best bet would be to purchase some T6 Aluminum gear to fit your plane from TNT landing gear at: www.tntlandinggear.com/

The TNT gear has solved the problem for me on two models so far and the new ones have performed very well.
