Mamba max heat problem

[brushlessboy16]

THe mamba max in my rc10b4 is temping at 175 at the end of a 10minute run, the setup is:


rc10b4

Feigao 7s (5070kv)
21/86
2s lipo
start power high
timing (0)
no punch control or anything else.

I took some time to cut the air vents in my proline vortex body for some more cooling along with the front windshield.

It was originally geared 24/78 which i found to be really high, changed the pinion and spur to the current gearing, and the problem persists. The motor temp is 145 after a run and the batteries are at 95. what am I missing?

If I could wedge my MMM into the car I would.
