Re: QS 3000w midmotor

Hi, has anybody measured the no load draw of this motor? Or could someone maybe just lift up the rear, spin the motor up and note power+rpm, that'd help me out a lot. Thanks, Matt Hi Matt, Sorry we did not test these. Could i know why you need this data? Thank you, Judy E-mail: judy@tzquanshun.com
