Can someone send me inside and outside diameters of the bearing shaft? I have a special application and must build the mount from scratch. I would like to go ahead and get started designing the mount in 123D.

Hi Pinson! I have the same issue. I will try to fill the holes of the propellers with exopy glue. After that I'll drill smaller hole into the middle of the propellers to make them fit better. Did you already solve the problem?

I found out you get more power using a 2.5x1 gws or equivalent prop. I have 10 of these motors, one in a 6" wingspan Ugly Stick, one in a 7" ultra micro Hots, one in a 9" micro Live Wire. I can't list all my models but I designed them, and built them from 2mm Depron for the fuse, and 1mm for the wings. I will post pictures on my site here.

Hi: Do you have 50 of the D1000 2 gram hextronic in stock? If so, since the web site only lets me buy 10 at a t ime, should I place 5 line items for 10 ea. Thanks

Received this VERY tiny outrunner today.
I can really recommend getting it out over a white blanket so You dont loose it.
I measured the amp to 1.7A with the suggested GWS3020(balanced) and a newly charged 130mAh FR-Cell.
Running it while holding it with my fingers it felt pretty strong (torque).

As propatapter i can suggest a bit of shrinktubing (2mm?) on the axle and reaming the prop a bit for a tight fit because the prophole is too large. Cheap and easy)

I tested these motors with a Turnigy 6Amp ESC, modified for 1S operation.
Optimal settings for this Motor-ESC-combo are:
- Cut Off Voltage: Low
- Start mode: Normal
- Timing mode: Low (or Middle)

I want to use this outrunner as a tailmotor for the DF4#3 micro heli,
so I did some thrust measurements with the DF4#3 stock tail prop.

Full throttle speed: 20310 RPM
Full throttle thrust: 16 gram.

I made the prop a bit larger with some tape (6mm on each side)
Full throttle speed: 15700 RPM
Full throttle thrust: 20 gram.

The standard DF4#3 brushed tailmotor (on full throttle plus full right rudder) runs at 17640 RPM.

The above RPM numbers seem to indicate, that these small outrunners could indeed be used as a DF4#3 tailmotor.

I tried this amazing tiny motor with TGY DP 3A 1S 1g Brushless Speed Controller. Start up is smooth and spins very fast without any issue. I intend to use it in my 4#3b sub-micro heli tail, with its 1mm shaft, the stock rear rotor fits perfectly. It spins up the rotor to full throttle no problem at all..
