Thanks man. Dropped to a 16/84 and temps on the motor were around 140°F before I tried adding sboit 20° boost on the esc and it shot right back up to around 180°. I actually pulled the diff out to look it over and cleaned/regreased everything reassembly si I guess I just need to het back to the track and work on adjusting it. Everything I've owned up until this SC5M has had a gear diff so where is a good place to start with setting it up?
