mx400 main gear
i have recently purchaced a used mx400 helimax and i was looking it over. the previous owner added alot of trex 450 parts, carbon fiber frame, cnc head and tail assemblies, motor etc. i noticed that the stockautorotationgear is broke. now i'm wondering if the trex 450 gears would work with a different pinion or do i have to install stock main and autorotation gears? thanks for any help

I don't know if it would fit physically (never tried), but it would need re-gearing if it did. The TR gears are 150 tooth, while the MX uses a 138T gear.
