I was looking through my box of old model airplane plans when I came across some interesting information. It shows a control line handle with batteries inside. The UP control line is connected to the positive end of the battery. The DOWN control line is connected to the negative end of the battery. One version shows the handle with an ON/OFF switch only. The other version shows the handle with a battery polarity reveral switch. The bellcrank has to be made out of some type on non conductive material. The 2 metal control lines are used to supply power to the airplane for, landing gear UP or DOWN, Pilot Eject, Bomb drop, landing flaps, engine throttle, parachute, etc. A tiny electric motor can be made to run in either direction on DC.

Has anyone tried this or seen it done?

I can remember when I lived in Michigan about 12 years old in 1962 one of the guys flying CL ejected a pilot with a parachute. I have no idea how it was done.

Did the plane crash after pilot ejected? That would be worth alot of scale points don't you think?

How big was the model? I have a half A biplane that has a small angle under the fuselage, connected to a third line, that pops the pilot out of the cockpit. He is mounted on a small cork. No chute, but he does get ejected. He's ugly too.

This has been discussed before I think, some very interesting points made. As you describe it, this would only work for continuous level flight (can't cross the lines--instant short). One line must be insulated, which of course 'WAY increases its drag over the bare line, with all associated problems. Then if both lines are insulated, they're 'WAY too big in diameter. At least that's my theory. Still, fun to think about.

Here is a handle that should do anything you want:

The indicated handle with a couple of batteries inside was sold in the late '40s. Don't remember the manufacturer, but it was red, and had a button on the top to close the circuit. I used one as a shut-off for the spark ignition engine. It required a 3 volt relay in the model activated by the current through the flying lines to pull in the relay and break the spark ignition connection. The lines first had to be coated with an insulating varnish, called General Elecric "GLYPTOL". The varnish added weight, and it didn't last long, because of friction of the wires.

C*x made a couple of power through the lines models culuminating in the Bearcat (Last thing I ever designed for those rascals). It used a 9v pack of 8 AA cells. But, if you wanted real performance, you ganged two 6v car (sub-c) packs in series. Of course the motor life was considerably reduced....

I had a lovely Pushy Galore prototype flying, but it never got produced.

Dr., you are ever so right.It was DECO 3-VOLT, TWO SPEED ENGINE CONTROL by Development Engineering Company. (DECO) of Hagerstown Maryland. I have a mint cond. unit consisting of a red plastic handle which takes two flashlight batts., a cardboard reel of stranded, insulated DECO LINE and complete instruction sheet showing relay and hookup to a spark Ignition system. I will try it out at Brodaks this year on a Fireball with a Forster ,29 Sparker. By coincidence, thats the plane the inst. sheet shows.Bob Zambelli (who really knowes his way around sparkers) has agreed to help set it up. By the way,did you ever finish that Palmer/Veco Hurricane?
