It could fit for motors like BETAFPV 0703 motors, Racerstar 0703 motors or Boldclash 0703 motors. Because of the hole for the motor shaft, it could not fit Sunnysky 0703 motors for the moment.

Recommended Parts

Really not recommend the 0703 motors with a 65mm frame ( like Beta65 Pro frame or BWhoop B06 etc). Why? The combo of 0703 motors and 31mm props (for 65mm frame) has a really low efficiency. Really not power enough. For the 65mm 1S brushless drone, recommend the 0603 motors (comming soon).

Here is the testing result of different motors and frames combo.

  •  Throttle value means the position when the drone hovers in the air.
  • Flying time is the time from OSD voltage value 4.3V->2.8V.
  • All tested with 4-blades props. 31mm props or 40mm props.
  • All throttle values are tested on full charged 550mAh batteries.
  • The KV value of 0703/0603 motors are both 15000KV.
