I have been running a mmm 2200 combo in my mp9e for about a month total now and have been in a constant battle with heat issues. Ever since I got it it has been a struggle to keep temps under 200. I geared it as high as possible and got some great runtimes but it actually seems to just make things worse.

I have checked gear mesh, drivetrain for binding, tried a bunch of different batteries, cut cooling holes in my body, set timing to 0 and even replaced the motor and esc. I'm stumped as are the guys at the track and castle phone support.

Right now I have a 14t pinion and 46 spur which puts my top speed just over 40mph and it comes off the track at around 180-190, after about 15 minutes with a 4500mah 30c 4s pack. I still can't get through my 5200mah packs without getting dangerously close to 200. I've tried as small as a 12t (geared for 32 mph) pinion and I still get temps of almost 200 after just 15 minutes.

Anyone have any ideas? I'm getting desperate, I bought this motor hoping to keep temps low...

I ordered an eagletree and a new temp gun, mine did seem to read about 10* hot compared to my friend's. Also replacing all of my bearings and rebuilding my diffs today just in case.

Ambient temps are about 75 now, but the really high temps were in 80-90* weather.
