Just wondering what the experiences have been with the XTM 2 speed buggy transmission. Apparently it is the same one that is in the Mammoth monster truck, but both vehicles use the same engine one just has bigger tires and different diff ratios. I just installed the transmission in my wife’s Kyosho inferno with some minor mods to the chassis however I also installed an HPI 4.6 with a Losi buggy pipe.   I managed to tear up the factory center diff spur gear but i believe the reason that happened is because the gear .engine wasn’t lined up correctly.
