HELP, nothing to describe, just plain help

[IFlyRCstuff]

a friend of mine gave me some old engines. two were gone, and one looks decent. it is a mccoy 29 (according to something on the side). he said he controlled the plane it was on with line (control line). so what i need help with is identifying what all it needs and if it is worth keeping/selling (and if so, price range????)
be forewarned i know nothing of fuel aircraft, so...

Yup, that looks like a .29 Red Head in good shape, but you never know til you run it. It was an economical engine. From what I gather, and I have about 10 of them to get running in different displacements, but quality varied from copy to copy. Some guys who were serious CL'ers would by 4-5 at a time to mix and match parts to get a good engine. I have a small collection of CL planes, some built that I got on craigslist, some still in sheets and sticks in the kit box.
Look up "shugemery" on youtube - he is also a member here. He has a couple dozen videos of his progression in the hobby. Shows how to have fun.
Cheers - Poughkeepsie Pete.

PS - Show us photos of the other engines, don't discount them, they may be good runners.

Thanks, so this is an engine that can be controlled by an rc tx as well, or...

im afraid you cant it is run buy a venturi system(like one of those cox .049 engines) not a carbourator. you can put it on an rc plane but it would run it full throttle the whole time till it runs out of fuel.

It also appears to be missing the plate that would go onto the crank, that the propeller tightens against. There should be a metal bit, that fits on the taper on the crank. The McCoy was a very popular CL engine. I can't speak to the quality, but I know the old CL guys in the club speak favorably of them. Maybe their favorable opinion is more sentimental than anything. I also have an old Red head, but haven't started it yet. I have heard that the old engines prefer a much higher mix of castor oil that what is typically available. The old boys at the club that still fly CL buy their fuel from some place in Oregon, and it's all castor for the lube, no synthetic at all.

Here you go:

This was/is a popular Control Line engine - so no throttle. Also, these are often run in four-stroke mode- sloppy rich. If you are really good you can tune for a 4-2-4 break which means it leans out when you climb so goes into a true 2 cycle mode, and then as you descend returns to "4 stroke" firing every two revolutions of the prop. I haven't gotten to the point of being able to tune that well.

They don't have mufflers so some clubs don't allow.

Cheers, Peter
