Do we need 6-8poles motors for 1/8 ep?

Most of the rpm limits I've seen for multi-pole motors doesn't matter as we won't hit those rpms in our application. To answer the original question, no, we don't need 6-8 pole motors as 2-4 poles do just fine for our 1/8 trucks. But I don't think 6+ poles will be a bad thing in our application. It just takes someone to try it out. The benefits probably wouldn't be big enough to say one is better than the other. Just more options to choose from.

higher pole means more work for the esc, and could (but must not)cause damage to the esc (in few cases), or at least gets hotter; I have read about that problem especially with some (german) flyware-motors (multi-pole up to 8). unless it's a high quality 2 pole motor, 4 pole motors have less problems with partial load, which is typical for our cars (boats mainly have full speed).

important for the use of higher pole motors is the right timing, in general they require higher timing (depending on esc, motor). timing also can prevent from cogging. when I run my losi 4 pole xcelorin on low timing, I have a little cogging, which disappears with a bit higher timing. and I just love the torque of that motor.

I think, any new good and affordable motor and more diversity is just good for that hobby.
