Brushless motors for the OpenFrame 3" and 5" quads. Sold per motor, 4 per quad, each wound for 4S or 6S.
OpenMotor is an OEM motor: an existing motor platform from an OEM motor maker with a custom OpenDrone bell and gold and green anodising. It is not an open motor design. This repository does not hold the motor design. It holds what OpenDrone measures and checks on the motors it sells.
Specs are the figures on the storefront page. They are the maker's figures, not OpenDrone measurements. "Not yet measured" means the storefront gives no value.
