sorry is the main crown and the 14t gear going into the gearbox both are stripping teeth and filling the box full of metal flakes, there is too much play and never seems to mesh correctly even after loads of time getting it to a point it felt perfect. but somethings missing clearly as they keep stripping every meet, its not that it cant be used its that it sounds like a mess, everyone is commenting on how bad it sounds hardly good publicity
if rango help me out with gearbox cases, grease, 2x 14t input gears 2x gearbox crowns i will be calling praise and glory for rango helping someone who has serious issues with their kit. but this will never happen. after all these would cost rango pennys.
