Posted on 01/31/2013 1:05:36 PM PST by mowowie
So i'm supposed to suprise my 7 yr old nephew next thursday and meet him for lunch at school for some kind of whatever thing... Anyways i thought i'd bring him a cool gift of one of those Cox .049 engine tethered race cars only to find that they they don't make them anymore? I looked it up on wiki since amazon seemed to be down. Production stopped around 4 years ago. Aparrently wiki is barred from FR so i can't post the thread but i had no idea of all the variants of this motor, wow......anyways.. JEEEEEZZZZZZ.....i grew up with those things, the planes, the helicopter, the cars, the stupid things i built with those engines attached..... Really makes me sad. There's still E-bay i guess and all but still. It seems that there is almost nothing left....
(Excerpt) Read more at yahoo.com ...
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.
I still have a scar from prop starting one of those devil engines
Also some on ebay....
Oh yea “Glow Plug”.
Glow Head was the nickname we gave to the kid down the street.
The old tether planes died because RC is so cheap now. The Cox .049 engine is gone as well because brushless electric motors are cheap and much easier to deal with. If you want gas-powered fun, there are plenty of engines available for cars, boats, and planes, but they are bigger than .049. They still use the old glow plug ignition system, but the new carburetors work much better.
Don’t mourn the end of the old tethered plane with an .049 engine. Rejoice that technology has given us much better toys!!
“I can still remember the smell of that fuel. It meant long, hot summer days with nothing to do but have fun.”
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.
I don’t have any scars, but I lost a few finger nails over the years. It certainly left me with a very healthy respect for prop safety when I got into flying the real thing.
I agree ... with electric power at the low end, gasoline power in the middle, and real live turbo-fan engines at the high end, the "good ol' days" of remote controlled toys are Right Now.
The Cox .049 and the “Red Head” McCoy .35 along with Amberoid, silk-span, hot fuel proof Dope and castor oil infused fuel kept me well occupied in my youth.
I built a boat. Used an .074. Lots of fun.
The new RC planes are incredible, jet engines , retractable gear.
Remember chasing a friends RC for miles after he lost radio contact.
The thing had 1 channel, rudder. The rudder fluttered back and forth. Plane turned depending what position you stopped the rudder.
Let’s see. Hmm either left(x) or right(0).
By jolly, it was digital.!
Had one of the things, never did get it to run.
As with all small displacement glow engines, the trick to reliable operation is to keep from trying to leaning the needle valve to get every last rpm out of the engine.
When I was younger, my brother and I would get flight after flight out of our .049 engines simply because we knew how to properly tune them. The engines started on the first flip and ran until they ran out of fuel.
Even with larger carburetors, it's possible to over-lean the mixture and cause unreliable operation. The real secret is to set the needle once, then leave it alone.
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.
I had the red, white and blue P-51 that you hold on two strings and go around in circles.
Put stick and tissue planes together and found out the dangers of “sniffing glue” by accident. Made sure I was in well vented room after getting up from the table and “WOW”.
I had the small Dumas Swamp Buggy with a Cox .049 and a 2-channel radio. It may not have had the speed of the hydroplanes and the big tuned-pipe engines, but it would run all day long. Later, I put an O.S. .10FSB on the boat. Boy, that woke it up.
