8 Pole Heli Motor in an E Revo?

[BrianG]

I like the fact that outrunners do make lots more torque, but personally, the advantages are outweighed by the disadvantages:
- Open design, more prone to rock/pebble damage
- Slower speeds require more thought on gearing. Direct drive setups leave little "gearing" adjustments unless you want to change diffs or tires.
- larger diameter makes motor mounting in a geared setup more difficult
- heat producing coils are inside the motor - I personally prefer the heat source to be outside where air flow is greatest. Although, the turbulence created by the motor itself is probably sufficient.

Still, it's nice to experiment!
