In comparison to the Arrma mount, the GPM aluminium feels lighter and stronger! So far it has kept the motor in place which I hope will last quite a while. When I was assembling the mount along with GPM's Centre Differential Mount, the two were not perfect aligned, but when you screw into them from the chassis they seemed to straighten up again. Also one thing to note, the stock Arrma screws will not fit on any parts of these mounts (except for the actual motor screws), so the GPM shorter screws will have to be used, but I am yet to report any bad news on those.

So far the gpm parts seem a good option other than standard parts,they look great fit how they should I'm very happy with them so far! I say so far as I haven't had a chance to test out my outcast or kraton since chucking all the aftermarket parts on lol can and will let you know if they are no good but so far very happy peoples
