Guys, its just a speed controller. Its fixed at full throttle. All the controller does is convert the DC to the proper AC current a BL motor needs.
When the dyno increases or decreases the voltage, it directly changes the input to the "controller", which effects the motor. Its very simple, and i think its a great idea.
You could make this with any brushless speed controller, you would just have to have it at full throttle. You could easily do this with a Nitro's fail safe, instead of using your radio.
Cheers!
