Hi, can u use 4 of these converters: Double-channel ultra micro brushless converter to run 4 hexTronik 2 gram Brushless Outrunner 7700kv motors from a MINI MWC Flight Control Board and DSM2 Receiver? And/or Is there any way to run the 5g hexTronik motor in this config from 1s lipo or lion? Thasnks. James

I haven't gotten my motors/props yet but here's my idea. Stainless Hypodermic tubing you can order online comes in many sizes. 17h (17 gauge, heavy wall) has an inside diameter of 0.039" (1mm) and an outside diameter of 0.059" (1.5mm). Cut a short length of that and press fit/loctite it onto the motor shaft. Props with a 1.5mm hole should press on well. I plan to try this when I get my motors. If you are in the USA mcmaster(dot)com has hypo tubing item #8988K37 $7.38 for a 1ft length.

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..
