hi Andy,

i don't know about manuals, i would not be surprised if there is not one but i don't know for sure.

with multiple turbines you still need one ECU per turbine. the ecus can communicate with one another on startup, as far as i remember that is the only advantage to linking the ecus in a multiple turbine install.


as for the control of the turbine, it is not voltage controlled directly, the input to the ECU is a servo signal.

if you are not using a typical rc receiver, a pulse width modulated servo signal that can be generated with a servo driver. these are little boxes with a knob that lets you move a servo.
