Impressive mini counter-rotating motor system.
Creates almost twice the thrust as similar sized single motor system
An interesting way to improve any models flying characteristics.Factory Spec.
Lipo Range: 2S 7.4V
Suggested prop: 5030
Max current: 0.2Ax2
Burst current (5sec): 3Ax2
Weight: 13g (including mount and wire)
Prop hole: 3/5mm
Dimensions : 24 x 13mm
5030 prop (Recommended)

The best motor for mini models... it trueThe 2 wires shown are actually 3 wires each. The separate wires are delicate and solid so do not bend them a lot or they will break. The mounting holes are tiny and will call for a precision mounting setup with TINY screws. I used 2-56's and still had to grind the side of the heads to clear the rotating motor shell. LOTS of thrust. I used a 9A controller for my tests and no heat was generated but lots of wind. Difficult to mount.each of the 2 wires has the 3 wires for the esc..
nicely made am trying for a miniVTOL type machine!!!
Little jewel! Here's bits from a review I have put at
The HC thrust spec of 180g at 7V and 4.4Amps is optimistic. I got 150g at 8V and 4.7Amps approx. The 5x3 3 bladers supplied are a good match for this motor and draw just over 2.3A on a fresh battery. You CAN'T use the "Related Products" ESC HC recommend. It will only survive 1S voltage. Use the Turnigy 6A ESCThe description is incomplete. Does the system include ESC/BEC? Photo shows only 2 wireskinda weired for brushless system, isn't it?The package includes the two propellers as shown a counter rotating 5030x3 pair.
Motor = 13.73g
Prop = 2.32g each piece.
i.e. Total counter rotating system = 18.35g
Testing for thrust, amp draw, rpm etc will be undertaken soon and I will release the results asap.
