castle motor temps?

There is for sure something funny going on there. My MMM on my 7xl geared for 42mph right now doesnt even come close to turning the fan on on my MMM. You really should get a wattmeter or some type of device to test current flow. Given all your temps it seems you are pulling quite a bit of current through there.

The only thing I can come up with is that maybe your tires are playing a factor but Dragon beat me to it.

My 7xl is about about 130 deg in 55 degree weather right now with no active cooling.
