Medusa End Bell Dust Cover

[Rnemhrd]

I have the RCM heatsink/clamp and a .5"x2" slit at the bottom of the windshield and on 4s geared for 45 I'm lucky to hit 100f usually 95f +/- at the end of a 8000mah pack with it 35f outside air temps. That is a lot of full speed runs and brakes at 50% using them alot. Never ran it with the ends open. The vent hole alows the air to hit the motor head on. May be why it runs that cool. That and the 35f outside.
