In Kashei we use a piece of custom electronics, to fire a Speed 900 @6S. But the setup is prone to molten motors, so it needs more R&D.

Best bet atm is to use the TZa85 hacked speedo to control the motor of an electric axe.
The hacked TZ85a is a good starting point but it won't be enough to avoid burn outs.
Currently working on code for an Arduino to sit between the receiver and TZ85a.
Managing the limits of motor actuation is important along with other things such as motor stall, soft start etc.
Just need to get some time to finish
