"I got this gearbox about 3 weeks ago. It arrived in a box just like the kingarms comes in. after removing the gearbox I found all the screws and bushing. The gearbox has a polished finish. With in the gearbox are some minor defects that must have been from casting, they are circular ridges that stick up in places. the bushing are very large 9mm(which I was expecting), the bushing however are very loose at the middle of the ball bearings, After installing the bushing which took minor shaving to fit them in to the gearbox, I placed an over shimmed gear into the gearbox to check the movement( moves in or out .2mm). A very smooth and precise gearbox but after the first complete install I noticed I was shooting full auto in semi. The cutoff lever tower part of the gearbox is smaller than the hole in the cutoff lever its self. I have tried two cutoff levers and all had the same problem, there is just to much play in the lever so it does not move in the normal motion.

Nicely polished
9mm bearings
Comes with screws

Minor defects under gear placement
A lot of play in the bushings
Cutoff lever problems (no semi even with a washer to help out the lever placement)
