we provide the timing circuitry with the pulse width from the throttle channel. I do see the ability to use the throttle curve manipulation from our transmitter to fine tune the throttle band to an individual's taste/setup.
The throttle servo moves in proportions with the width of the pulse (1.5ms +/- 0.5ms), which would simultaneously be fed into the timing circuit. Both the servo and the timing 'know' what we want, i.e., idle, midrange, etc. I do not know how many points currently are available from the transmitter that heli guys play with. With a minimum of two points (in addition to 1ms and 2ms) we should be able flatten or steepen the part of the curve where it matters most to each engine/setup.
Such an ignition could be plugged into the receiver with an extra port into which we plug in our throttle servo. This would allow the servo to be placed close to where we mount the ignition unit.
Going to reinvent the wheel again!!!!
Was here 4 years ago. It worked fine just was not "idot proof". To many things to twiddle with and ended up with a messed up engine ignition. If we ever got it working the next step was controling fuel injection from the same information .
