Twist-55 and Schulze U-Force 75

Perhaps a fan would keep the heat in check. You will have to play with the gearing a little bit. It could be overgeared or undergearewd. Try gearing down and see if the heat lessens, and try gearing up as well and note the temps. It will take a little playing around to find the "sweet spot". I always dial the power out a bit on my radio if I need more control. Just a tip you may use, if you have an adjustable radio.
