Lehner 1950/6 or Plettenberg BigMaxximum ?

perhaps the shadow is different in this magnetic resistance, i don't know.

This resisance is causing a rather harsh startup with my bigmaxx.

WOW, lets be careful here...
Any 4-pole motor will have the same story. Plettenberg is a torque-king motor in its size. And with right controller it starts much easier then 2-pole, because it stops always in between poles, not in random position. With desing you can minimize pole-pulling-holding effect (braking) but only with outrunners you can eliminate it completely.

Plettenberg is a very nice motor, but doesn't have as broad RPM range, with high efficiency) as Lehner or BK 2-pole motors. But it does have a torque which most motors do not have, and 4-pole design mean twice more torque with comparison to the same wind 2-pole motor. So if you have a tranny which expand this range then it might be not that bad.

And ones it spins all the pole pulling-pushing is under control and doesn't affect anything.

Plettenberg at starluckrc cost around $210-235

P.S. Rene are you sure Wanderer is smoother then Plet?
