I'm hoping that I can fit the HL 'stug' gearboxes in mine, as I'm not a fan of the Asiatam / Mato gearbox design. The version 2.0 Mato gears are better than the original (asiatam clone) version as they have a better load path from the motor to the final drive, but ultimately its still a bunch of gears spinning around a very thin shaft - either the shaft bends or the gears wear themselves (or the shaft) out very quickly due to the high unit loading on the small diameter shafts
