(Edit: The 3000kv 1105 motor was insufficient on 1S power, so it was swapped out for an 1108 6000KV motor that proved successful. Later I tried a 1207 7500Kv and 10A ESC that proved even faster, but drains the pack quickly.)


Final step in my first 1S powered Mustang mod project is swapping the lifelimited brushed coreless motor and gear reduction unit with a direct drive brushless outrunner motor.

This requires the use of an external brushless ESC. My second Mustang mod was easier, as I just swapped in a Spektrum 2S brick with a builtin brushless ESC. Making the first plane brushless is a bit more tricky.


The Spektrum AS6410L receiver brick (Used in the Eflite PT17 Stearman) does NOT offer an external ESC output as the AR6400 bricks do. I guess this bit of code was left out of those AS boards. And so to get a signal from the receiver to operate the brushless ESC, I had to use channel 6 on the brick for throttle control and a transmitter that offers channel mixing to connect channel 1 (throttle) and channel 6 (flaps) together. My TX choice was a Spektrum DX6i.

This video assumes you have already separated the wing and replaced the stock receiver brick with a DSMXcompatible unit. My video showing my brick swap in this plane can be found here:    • Eachine Mini Mustang P51  DSMX boar...
