Well so far I have a FUZE 1/10 brushless ESC already mounted. I have ordered the Brushed version motor plate so I can mount a 1/10 size brushless motor. Will let you know how it goes. Will take some pics tomrow but the ESC fits with no problems at all. Just made a mounting plate for it that slides into place just as the smalle 3m did. Works perfect, right now with the 28t pinion and a 55t spur I can run speed runs until battery is dead and only hit temps of 108 degrees. That to me is worth it.... thanks for the help guys.
