"Cool product, good platform, gears that come with it are trash. Yeah, i voided my warranty by fixing it myself, but im not going to fuss with warranty to get a new gearbox for the sector gear to snap two teeth in somewhere between 10-15 shots. So... expect to replace your gears. Rest of the gearbox seems fine so far.
