Tee Dee .020

That isn't the most clear picture, but it certainly looks like the case is gold to me. The throttle ring is easy to swap around if using an R/C Pee Wee cylinder. While not original it's easy to change and those RC .020 cylinders have value.

Looks gold on my display too.

Can U return it if not an .020 but it does look like one ????????? can't see the color here Pic too small !!@??

I asked for a better picture.

It surely is a gold case, if the price is fair grab it. Put a regular .020 cylinder on it and sell it. Put the .020 cylinder with the throttle ring on a Pee Wee, sell it and double your money.

Looks like the person made a control horn for the standard Cox throttle ring by mounting it using the two holes in the C ring, which normal are where control rod to servo goes. That is one way to make the engine throttle-able.

Much better picture.

Of interest is the custom red anodized 4-bolt aluminum engine mount back. The standard non-tank back is plastic 2-bolt. Looks like you have a rarity there.

I felt it appropriate to ask a Cox .020 engine question here in his thread;

Did Cox ever make a high-compression glow-head for their Tee Dee engine variants? Did Cox ever make specially-ported (boost-ported) cylinders for their Tee Dee engine variants?

I assume that the Cox "Pee Wee" (reed-valve) .020 engine was designed prior to the Tee Dee (rotary-valve) variant.. but that's purely speculation on my part.

I also wonder about the .09/.15 engines. Cox didn't make reed-valve variants of those.. but there were Medallions and Tee Dee's in both displacements. Were there specially-ported cylinders and/or high-compression glow-heads that separated the Medallion engines from the Tee Dee engines?

I can't say about the Tee Dee's, only have one, an .020 and rest Medallions. Both my .09 and .049 Medallions have SPI and only one bypass port. These are the earlier ones. The .049 cylinder resembles the Babe Bee one, may even be the same one, I don't know. Recently someone clarified that the heads with the knurled inner ring around the glow head electrode post is the Tee Dee high compression one, which is also suitable for the other Cox engines. (May need an extra gasket or two to tweak compression level.) I've got a few donor 290 engines. Interestingly enough, a couple have the Tee Dee head on them.

This is why I'm not afraid to try dual port non-SPI cylinder and throttle ring muffler on my .049 Medallion. Same type setup provided more power on my late 1970's R/C Bee than a Babe Bee, so it should do fine on the Medallion as well, converting it to a decent .049 RC engine.

Thanks George.. interesting info. There are so many possibilities for building a Cox engine to perform the way you need it to!

You're welcome Roddy. BTW, noticed how Joe Cesere is dressed. Was he in his absence canonized to CEF sainthood?

In a word “No”

The Pee Wee and TD cylinders are identical... dual bypass. There are .020 heads that are plain and some that have knurling like the TD .049/.051 .09 and .15 however, the combustion shape is identical to the non-knurled .020 head.

The are only high comp heads for .049/.051, .09 and .15.

I must beg to differ. While I know of no .09 reed valve engines produced by Cox, the Olympic and Sportsman .15 engines were rear reed valve induction engines, much like the .049 Space Hopper.

I have to say, no disrespect, but do we have a better picture of Joe to remember him by?
Nothing against Nuns (well?? maybe those with beards?? ) but is that the image we want to be left with?

I was running my TD .15's today. I have to say they're pretty neat running engines. They sound awesome. The Medallion .15's and the TD .15's have different porting just like the smaller variants. The Medallion has the single port while the TD's have the dual bypass. My TD .15's run on Medallion glow heads. I have only have a few TD .15 plugs left. Just like the smaller versions, the knurling on the top indicates high comp vs standard. I would like to have a head with turbo plugs in them as I think this would offer similar stock performance.

Joe was one of the good ones and is missed!

I have 4 Medallion .15 engines that I accumulated over a 5-6 year span from various people.
The earliest ( I believe) and by far the most abused had the Medallion single bypass cylinder (and wrist pin piston) you mentioned.
The other three have 2 bypass ports and a wrist pin piston like a TD .15.
I thought I remember reading somewhere that Cox must have just used the on hand TD units rather than do another production run of single bypass Medallion cylinders.
FWIW, Steve

Rod, I really don't know Joe and it appears at this point he was quite the clown with a good sense of humour. I don't know where that photo came along, but I don't think that others found it somewhere and posted it here. I'm being a little presumptuous, but thought may be that Joe himself posted the photo somewhere here himself.
(Is that not true, Roddie?)

Difference in power between the Pee Wee and Tee Dee .020's seem to mirror the difference between the Black Widow and Tee Dee .049's.

Both .020's are neat engines. I liked the Pee Wee because it is a torque engine, will spin larger props with ease whereas the Tee Dee likes smaller props and higher RPM's. Seems to be a renaissance with the smaller engines these days. I've noticed that E-Bay bids on the 1/4-A's seem still to do well.

The photo of Joe Cesere dressed as a nun is one that (I believe..) "he" originally posted here. I saved it at that time; thinking that it was humorous. I have no other photos of Joe.. but I'd bet that he would want to be remembered in a way that would make us smile. I meant no disrespect.. and am very sorry if any of you took offense.

Roddie, I don't think anyone truly took offense. You'll even noticed that Rod put a smiley with a sense of humor, "Nothing against Nuns (well?? maybe those with beards??   )". I was a little clueless, because I really didn't know Joe, so what I said was to be taken with a sense of great humor.
Have a great New Year!
