Ah, that makes alot of sense when its explained like that.

Increasing the load decreases the impedance, which increases current draw as a result = hot motor correct? A bit like working out increases adrenaline flow (reduced impedance), but you also get rather hot and sweaty (increased amp draw).

Decreasing the load (gearing down) increases impedance which restricts current flow and amp draw, so you run cooler for longer basically.

A higher voltage will make the motors life harder since when its spinning faster, its workload is increased (and it has limitations to how much work it can do regardless), which also decreases impedance = more heat.

Reminds me of the Hvmaxx- high rpms + weedy magnet = low impedance, hence why it always runs hot in my Gmaxx. Gearing down helps, but then the speed suffers....

Thankyou Brian, I think I learned some very valuable info there.
