Bench test: McCoy Redhead .09 diesel model airplane engine 

those old diesels still amaze me!

I had one of these when I was thirteen. I was using it in tether boats and when I broke the crank pin it broke my heart.

Get a battery starters, saves you from getting the “bent finger” problem. And every small airplane builder knows what I’m talking about. I had that problem about 65 years ago, now I have a arthritis knot on that finger that can really hurt when rilled up. Great vlog, thanks for sharing.

So satisfying.

That's a nice little engine, play with it a bit, and you'll find a nice piece to put it in and fly. Thanks.

Use Ether Kerosin Castor oil fuel mixture, castor oil is lubricant. Adjust compression and it will start and run till fuel tank is empty.

Yes, you must close needle, finally revs up when fuel empty ;-)

Thes little motors are quite fussy starting. What are you using for fuel?

Interesting video good job

Very rich run.

Neat little motor and I wonder what designs were on the market that fit it as a power plant. Would be nice of course to hear it peak out on power delivery. Thanks, Paul in Thailand

Great to see one run Thank you But they do make starters.

Está este video en Instagram????

why is it so hard to start

A close friend wouldn't wish one of these on anyone. The teflon contra-piston didn't survive a few test runs.

Never mind increasing the compression. Close the needle valve a bit. Ha.Ha😀

why not just use and electric motor on thehub. what kind of fuel does it use.. andhow many hours will such a motor run.

Sorry, the provided o-ring didn't last for my engines.

Means it's running too rich.

3:15 there that wasn't so hard was it!

Very nice engine. I'm guessing that diesels can swing big props for their size. Has a nicer sound than the glow engines around the same size too. You gonna put that puppy in a FF airplane?

Is it the real McCoy?

How to sell

Better watch out for those propeller blades

would be better started with a drill no?

Teflon contra-piston were the weak point on these engines, had an .049 and .099.

Ignition at 3:00

I’m trying to find videos of how model planes work & are made but I keep finding videos about wooden model planes ✈️? 😒

fuel name?

До конца не досмотрел-так мы запускали двигатели,когда нам было по 10лет. А этому "дяде"-не к лицу так ковыряться...

I dont understand how they are called diesel but have carburetors

I have frog engine. I want to sell it. If anybody interested please let me know

My 12 year old son Junior was using some of this Duco Cement to put together a model airplane when he passed smooth out at the kitchen table. His head hit the table so hard it left a knot big enough to tie a horse to. Had to run him up to the emergency room they kept him up in the hospital for 3 days. There is something in that damn glue that made him pass out. Does anybody know who to contact with this company? Because i'm out about 900 dollars to the hospital, not to mention the kitchen table that got destroyed when Junior hit his head on it. It really pisses me off that they could sell a glue that could be that toxic, and make a kid pass out. I'm wanting some money out of this deal. Who should I talk to about it?

3:14 Thanks me later🥵

Clumsy
