Wasn’t it a glow plug? I still have the scars on my finger from starting an airplane with one of those things by hand, almost 59 years ago. I’m sad my grandson won’t have that opportunity.
Oh yea “Glow Plug”.
Glow Head was the nickname we gave to the kid down the street.
Cox engines used a 'glow head', which is to say that the platinum element was built into the cylinder head. When the element wore out or broke, you replaced the entire aluminum cylinder head.
Other, larger engines glow engines use a glow plug, which is separate from the cylinder head.
Control line airplanes are still available - do a bit of hunting online.
Heh, remember the Cox-powered dragsters that ran along a taut string? I think there was a bead on the string that shut off the engine and popped the drag 'chute.
your comment is cracking me up.
I can’t tell if you are being sarcastic or not.
LOL
I had three or four of the tethered airplanes;
P-40 Warhawk
P-51 Mustang
F-4U Corsair
I even had the competitor (Estes ?) acrobat airplain in bright orange.
Loved those things.
When I got bored with them, I’d shave the vertical stabilizer, which was always pointed to the left to cause the tethered plane to turn left. Then, I’d lock the elevator in a 10-degree position and let the plane roar down the street until it took off and careened into some neighbor’s house.
I now recall the Stuka, which we loaded with M-80s for her final flight.
