Overall good motor/gearbox pair. Motor shaft is 1.48mm (1.5) and gearbox shaft is 3mm (threaded). Ran with 5x5 and 6x4 prop, 2S 500Mah LiPo on a small (26"/66mm) scratch balsa Cessna O-1E Bird Dog - free plan from Outerzone UK. Very powerful for the plane.
Gearbox is aluminum with ball bearing "bushings". Mounting the box took some creativity as it has no mounting holes. It does have a oval slot (approx. 8mmx4mm) for a mounting pole.

I wanted the Turnigy 1220 motor - out of stock. So I bought this system, pinion very hard to remove - anyway good motor.

The one I got was binding up.Upon closer inspection I found the inner rotating portion of the motor wobbling and making contact with the outer windings.

The dirt first:

Weight: 17.9g

Ratio: 7.1:1

Motor KV: 11350

Motor Interal Resistance: 0.21ohm

Max amps: 7a

No load current: 0.8a

Max volts: 7.4v





These are specs as tested, also came with a tag from factory testing, stated 7.4v no load test, 11830kv on prop shaft, 0.8a current.



From testing and Ecalc I have determined it to have 0.18ohm internal resistance.

Ideal props: 8X4 8X5 9x4 9X5 on 1s

Ideal props: 5X5 5x6 6x5 6x6 on 2s

HInt,

Remove the shaft and loctite the spline. The large cog is not locked well enough on the spline and will come adrift without too serious a consequences, but renders gearbox inoperable until fixed.

Put it in a small SU27. 50cm wings. I can do 3D. Use 1s 1,3mah. Wants more?

Has any one figured out the gear ratio? Has any one Tryed two cell operation?

Smooth operation on bench test. prop shaft seems large for motor size, could save some weight with smaller gear and shaft combo. Great deal nonetheless.
