Neu 1515 Heatsink with cooler?

[zeropointbug]

Why do you want a heatsink w/fan for a Neu motor? Do you have a smooth version can? If so, why?

Generally, you should never need a heatsink/fan with a Neu, even a smooth can version, if run within typical circumstances.

You need to tell more about your setup, what motor (# of cells, and Kv.), vehicle, gearing, weight, temperature where you live.
