I have a non-PA question...

I'm going to ask a line of questions but if it should be moved to electrics please do so. It's a thought I've wondered about electric carrier and electric's in general. I know that there was a time that speed controls were basically just heavy mechanical devices.
What i am wondering is , if there is a way to use a esc conected to a board with a switch that would allow a carrier model  to work similar to  having a mechanical switch connected to the esc. or do they already do that. Please note that this is just a question I am asking for no other reason than my information.

Jim.  Long, long ago, we flew our spark ignition planes using insulated lines.  Sending a current through the lines closed an on-board relay to kill the engine.  Since carrier does not result in twisted lines, such a scheme is quite practical.  Ordinary lines are coated with "Glyptal", a G.E. varnish that is flexible and very durable.  For carrier you could easily send pulses through the lines (nominal 1.5 msec for neutral, with 1.0 msec and 2.0 msec extremes to signal an ordinary R/C servo.  The servo battery would remain on board, but the "signal" power is at the handle, along with the digital portion of an R/C transmitter--no RF needed).  Of course, the servo would be a throttle unit.

I'm surprised people haven't already done that.  And maybe someone has.

Clancy Arnold (see his UTRONICS CONTROL in the vendor section) has a nice electronic setup.  one-four channels.

Well I wast thinking as a true control line modle and using just engine in model and a handle , Thats why I was thinking that the ideal would be use the same 3 line handle and a way to control the rpm should be in the plane.
