Actually, it turns out that, once broken in, these gearboxes can be back-driven with some effort. We don't want to make a habit of it, but it's possible. The spider couplings also help with some of the shock load. We disassembled 1 gearbox after 2 (often rigorous) regionals and a few demo events, and the gears showed no visible damage.
