*IDEA*
I noticed when installing my motor today in my build, there is a small gap underneath it once tightened down. The chassis would be a great heatsink! I'm sure someone can tool a piece of aluminum to fit between and transfer some of the heat to the chassis to help keep temps down. Putting a "curve" to hug the motor would keep it from moving around.
Please remember this post to whomever makes this and possible sells it, I want a demo
