gke00 Motors now tested 12.3V using a 3 blade 5045 Dalprop Cyclone. First run 590gm thrust on three motors and 570 on the fourth. Second run 720gm on three motors and the fourth variable from 670-700gm. I think the bearing lubricant was stiff for the initial run explaining the increased thrust. The fourth motor is suspect so looking for a well matched set in the same batch seems unreliable. Not seeking a refund.
