I finally tested my new B P Hobbies A2212-6 motor. 2,000 KV.

Ran good . Horrible vibration. Shook a 4# machinists vise easily. Turns over with either the Worlds strongest magnets or a pressed too tight bearing. NO end play.

Any other $ 20 ..6 turn..2000 Kv motors. USA retailer only ?
I need low voltage, higher amps. due to my B & D VPX cells.

Thanks, Rich.

Did it vibrate at no-load? Are you sure the prop was balanced? If it is indeed a bad motor send it back to BP for replacement.

If you were using a prop saver that could be the problem also. Prop savers dont work well at hi rpm or much over 75-100 watts max.

It was doing it on 6 volts and no prop. Just the 10 x 10 mm stick mount in the 4# vise. Greg @ BP said it sounds like the 1 or 2 baddies that do happen. GWS motor runs smooth in the same setup.
It is going back for replacement.
