What's the smallest well made glow engine for use in planes? Not a fan of cox as they look a bit toy like. I've found this AP... anything else out there?...

Norvel engines from Russia are awesome with there Rev lite (ceramic sleeves). The AP .06 is a Chinese made clone of a Norvel with "ABC". You can get the real Norvel for a couple bucks more, and it has a ceramic clyinder.

Sounds good. Do you have a link?

Also, does anyone have a link to a picture of an Enya 06? These sound good...

I do not have a link, just do a search on the net. SIG MFG. is the distributer in the states. Norvel also make's a .074 which as far as I remember was touted to be more powerfull than an OS at half the weight. Thunder Tiger also made a little one, but it is heavy, as I suspect the enya also is, compared to the Norvels who pretty much bench mark the modern 1/2A in my opinion.
There is a section on 1/2A'S here.

Well, the Cox .010, IMHO, IS a well made glow engine. Though I have not tached mine, they are reputed to turn 30K RPM. Here are a couple of pics. The red one is an earlier model and the black one is a newer version. Both start easy and run well.

Perhaps a better definition of what you need will narrow the suggestions.

As mentioned, the AP is a Chinese knock-off of a pre-revlite version of the NORVEL engines. If your needs are what I think, the NORVEL Big Mig .061 is an excellent engine.

The Cox engines are well made, but the Tee Dee's are more user friendly due to the rotery valve instead of the reed valve. Also no carbs. But if you don't need a carb the Cox Tee Dee's are great with more power than a Norvel of the same size.

But the norvel has a mufler, and looks like a real engine and has a conventional connecting rod.

Sport_Pilot

OK, but the muffler does noting but slow it down. I don't think the con rod works any better, and looks are not important. The lack of a carb however is important.

Thanks guys. I had a cox 010 many years ago.

I just ordered a little diesel beauty. Check out the review's detailing thebuild process...

By far, the Cox TD010 is the smallest production engine ever made. Cox didn't stay in business for as long as they did my making a lousy product. The Cox line of engines are some of the highest quality engines ever made. The machining tolerances were 25 millionths of an inch. The first company where you didn't have to buy the piston and cylinder as a set. They were interchangable. The Cox TD 049 and 051 were THE engine to use in class 1/2A and A free flight for 40 years. The TD 049 held the 1/2A speed record for at leat 30 years. The Babe Bee 049 was made in the miilions, more than any other engine. The break in was ONE MINUTE. I used dozens of them. They were easy to use and well made. Owned Cox engines from the little 010 up to the Special15 MkII as well as the conquest 15. NEVER had a bad one. I still have a 4 gallon fuel box full of them New and Used.

There is actually a motor SMALLER (if you can believe it) than the .010 Cox, but for the life of me...the name eludes me.

I second Loughbd's comments on the Cox tolerances. They are far, far, far from being toy-like....quite to the contrary.

Cox's tolerances were mind-boggling in their precision. That they were doing it years before CNC machinery was in use, AND selling the product at a price a 12yr old paperboy could afford is staggering.

Quite an achievement IMO.

There may be a smaller ENGINE but it was never a production ENGINE. The TD010 still holds that distinction. Actually Cox prices weren't the lowest. Wen Mac's were cheaper but hen they were lousy engines. Cox babe Bee 049 was $3.95 and the TD 049 was $6.95. his was when a McCoy redhead 35 by Testors was $5.95. The TD010 was $8.98. That was big bucks to a guy that made 20 bucks a month delivering the Seattle Times.

Try to tough the rotating propeller with the fingers. If very painfull in the fingers, the engine are not a toy for children. [>:]

Give me a break. I got my first model airplane engine when I was 7 years old. Mygrandfather gave it to me. It was an OK Cub 049X on a Walker Firebaby C/L airplane. I still have the engine. My brother got a Cox prop rod for selling greeting cards when he was eight. We had to start them by hand. You learn very early in the game not to put your fingers in them. It's a famous story in my family. My Dad showed my brother how to start one and how to be careful. He told him, "I'm not going to tell your older brother be cause he'll learn the hard way. I still have the scar on my left middle finger from "learning the hard way". I have been bitten by propellers more as an adult than I ever was as a kid.

That is the same philosophy that got model airplanes thown off of school grounds. "Oh no!!! They might get hurt, It's too dangerous."

So just how old does one have to be to play with a model airplane engine?? Hmmmmm??????? 18, 21??

All:

At the end of the last ownership (pre-Estes) Cox made a pretty good 049/051 throttled engine. Their first attempt used what looked like a Tarno carb, and Cox' carb didn't work any better than the ones bought from Tarno. First picture. Their last version though, had an adjustable air bleed and a proper muffler. It works very well. 2nd picture. They weren't cheap. The first version cost me about $82, and the last of the later version I bought was almost $110. I have the one on the air boat, and two NIB for my next 1/2A twin.

And there is a version of the TeeDee 010 that throttles well. An outfit called Micro Flight sells them, about $90 for the complete kit including a special tank and fuel. Third picture. I have tach pictures of the 010 turning 27K at full, and 4400 rpm at idle.

Just FYI.

Actually Cox hasn't been owned by Cox since 1969 when Mrs Cox died and Leroy Cox sold the company to Leisure Dynamics. Bill Seltzer bought the company in 1983 when Leisure Dynamics went bankrupt. Estes/Centuri Corp bought the company in 1996. They are now made in China. Quality is actually as good as ever. Still made on the Cox equipment. They just stopped making some of my favorite sport engines like the medallion series, the great TD020, 051 and 09.

I think you missed my point: cox LOOK toy like. I did not say anything about the engineering, just the aesthetics. I already stated I owned a cox 010 remember.

The smallest diesel engine in production now is an .03 See http://www.cafes.net/doctordiesel/

How about cox 020? very much alive avaiable in a good LHS I have a new one and a Davis diesel conversion head for same both NIB

Since the TD .020 went out of production, my guess is that you are referring to the Pee Wee .020, which is a reed engine. Both are excellent engines. Performance edge went to the TD, but the Pee Wee is also an excellent engine.

The one in the pic is, I believe, the one I got when they were first released in the mid 1950's. I have a couple more, one in a plastic Pitts.

The starter spring to the left is for an Olympic .15 which grew legs long ago.

IMHO, the only reason they look like toys is because many of them came in toys. So be it. I like toys...actually, what are model airplanes but toys?

If it was a production engine, might you be referring to the Bambi .009?

I'm not sure of exact sizes but if memory serves, the Bambi was the same size as the Cox.

Smaller is an AM .007 ci diesel. Made in England. I'll take a pisture of mine and post it.

I'd love to see that AM pic!

I remember seing a tiny diesel about ten years ago - shiny head with matt black body. Wish I bought one then.

I used to own the 03 Paw! Mine was pretty spent and it took an age to start. It wasn't all that well made and I think it had worn out a touch.

At one time G-mark use to make a tiny .03 with a throttle and a muffler. Glow fuel I can't find my old documentation on it , but here is a picture I found about a year ago (below). Was a nice little engine. Every so often they show up on E bay.

Just as a side interest to the threat.....

The engine in the photo here is not in production, nor are they available, but it was a special 'government' project Dub worked on a few years back.



We use to call it the worlds tinyest ducted fan engine .035 displacement, 28 grams. Turned somewhere around 40K rpm. 4 were built, only 1 was ever run. The project they were intended for ended up getting bigger and heavier - and ended up outgrowing this little jewel.

Awesome picture. That is pretty damn collectable!
