The xtm mammoth st is a great platform for a brushless conversion. I purchased my motor mounts and two speed pinion gear at fine design but I am sure Mike can hook you up also. I run a 7xl monster esc combo on my two speed mammoth st and it has to be moving at least 60+mph on 6s. My 2nd mammoth st with the center diff now has the monster system 2200kv and it is pretty fast even with a center diff. Stock parts can be found at hobbypeople or ebay.Most bodies made for the Losi lst2 will fit the mammoth st chassis. Now get to work on that conversion
