SunnySky V4006 High Efficiency Brushless Motors

Great product

This motor performed exceptionally well. It started reliably, delivered smooth and consistent power, and proved to be highly efficient throughout its operation.

Impressive motor

V4006-320KV -- The quality seems impressive and this appears like a work of art. Smooth and low noise. I tested this on my prop tester with 12" to 20" props. Turns out to be very efficient. Quite better than its competitor MN4004-KV400. Note that the comparison was in the lower power range and neither motors got hot. The difference was significant. I would recommend this and am purchasing another unit.
