My .04 cents (inflation), I ran an arrma blx 2000kv motor with big trenchers and badlands mx3.8 and an 18 tooth pinion. On these configurations she ran hot, like 200f hot. After breaking multiple arrma motors, I went to castle. Ended up with the 2200kv sensored motor paired with a castle mmx, I dropped down to a 16 tooth pinion and put shockwaves on her. Sure it doesn't have the cringe worthy power it used to but, I no longer have heat to worry about. Mind, this is all on 4s (which is all this truck really needs), so to get to the point.... tires, in my opinion, have a huge role in system temperature. Tekno recommends shockwaves or the O.G. badlands, I imagine it's for a reason. Running 6s, keep the tires smaller, gear down and run a bigger motor. This truck will eat electronics for dinner if you're not on point.
