My first plastic A gear wore out after 70 flights. I've since switched to a metal A gear. Now my metal A gear shows no wear after 120 flights.
In my experience, when the 130X tail blades touch the ground, the C gear strips. (Actually, the torque rod strips the hole in the C gear.)
Are you saying you're stripping the metal
A gear? I've never heard of that. If so, is it possible that your B gear has worn or chipped teeth causing the wear? Is it possible that the A / B mesh is too loose?
