The 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.

Little jewel! Here's bits from a review I have put at

USUALPREFIX[DOT]rcgroups[DOT]com[SLASH]forums[SLASH]showthread[DOT]php?t=1118210



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 ESC

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.
