I want a look inside the HW motors myself. My buddy wants a budget buffy system, so he may get the HW80 and one of the motors, probably the longer model, should handle the heat better?

Yes it shld handle better heat but also draw more amps

Seems like the difference between a L can and XL can feigao... Similar KV and the longer can will draw a bit more, but run cooler and thus more efficiently. So the amp draw ends up about the same... But the longer motor can run longer and will put out a bit more power.

Actually the bigger can simply means tat it has a higher heat capacity for the same load. It doesn't necessary mean that the larger can has lower intrinsic efficiency.

Then again with a higher heat capacity, the motor runs cooler on the same load. And since the motor runs cooler, the effective efficiency is increased as compared to the smaller motor.

The larger can motor should be running at almost the same current than the smaller motor if both have the same kv and the vehicle they are run in is geared for the same speed.
