Absolutely!

I thought much the same when they first appeared many years ago. The fact that they are made from fully machined bar stock just like the Cox engines and their choice of colors certainly adds to the suggestion.

Someone should buy it and put it in a scaled up GLH.

Lol i am talking to the guy now about it. i was thinking about a big Honker instead.......

These were produced by Hans Hornlein and Co in Germany in the 70's-he was previously known for the Taifun range of diesels and glows from the early fifties to late sixties. IIRC there were about 5 or 6 sizes in the range-from a 1.8cc '10' right up to about a '71 or thereabouts-all of very similar appearance. They were sold in the USA for a while but didn't seem to make much headway in the market. Crop up on Ebay from time to time. There's a couple on Ebay right now-and my earlier recall was right-reading off the box in one of the auction photos they were made in .10, .15, .20, .40 .61 and .76 displacements-

yeah just by looking at the engine doesnt seem like it will be a strong engine with tiny transfer ports. What else do you know about these engines?

gcb

I believe the Profi's were known as very powerful.

As to the real production TD's, that would be the .15. Lower right is a first series TD .15. There was a Mk-2 that was stronger and more powerful, and a Mk-III that was of limited production because Cox came out with the "Conquest".

Also shown, top row TD .09's, rest are .049's except red one is .051 with OEM needle and plug.

that profi doesnt look like it could be that strong of an engine though because how small the tranfers would be.

Really wasnt asking what the biggest TD was, but since on the subject i was just cleaning garage and found my TD 15. I dont know which one it is but the plastic carb is red. I think its the low pwer one lol. its not new wish it still was. i bought it then ran it on the bench twice then put it away. this was back when they were every where and easy to be had. i remember TD.049 and .051's going for 25 dollars back in 1992. should have bought 100 of them lol

Also my TD 15 doesnt have the screw in throat and needle valve set up its all in the plastic housing.

That would be a Medallion .15.

Well, shiver me timbers - a visit from the past. I thought perhaps DB had gotten too feeble to type anymore.

Hey DB, I thought I remembered that cox made at least a prototype of a .40 size engine?...dont know that it was TeeDee type engine or not....Rog

My Feedback: (1)

A handful of these were made.

The largest "TD" style engines were the .15's.

Wasn't that going to be designated "Conquest 40"?

George

DICKEYBIRD

Feeble? Definitely. Plus I'm too busy trying to help my kids (that so-called moved out) survive this world I brung 'em into to do a whole lotta typin'.

By the way, I prolly forgot to tell you fine fellers I is a grandpa....again. Youngest daughter Rachel & hubby begat us a beautiful baby girl a few months ago. Everybody's healthy and baby Anneliese is plump as a tick on a dog so I shouldn't be complaining. Oh, & oldest daughter Kim is busy growing us a grandaughter that's due later this year to give my grandson a playmate.

Andrew

Boy, that part I fully understand.

Congrats on the grandbabies, here and on the way.

Now that you've found your typing fingers, don't be so scarce.

This is the biggest TD I ever saw, don't know the displacement though.

Resetting that ball socket looks like a 2 man job!

Andrew

Boy, I'll bet the neighbors complain when that thing gets cranked up.

My Feedback: (3)

I'd scratch build a control liner for it, but the handle would need to be big enough for both hands.

AndyW

My Feedback: (1)

Apparently it needs 12 volts to light the glow plug.

As I understand the history of the TD 15, the first model had the ball and socket piston. The cylinder was too thin and would break at the exhaust cuts. The TD 15 was soon replaced by the TD 15 Special (called by me the MK I) with a piston pin and a thicker cylinder. Then replaced by the Schnuerle ported TD 15 MK II Special. I've had two Medallion 15's, both with piston pin pistons. On the other hand, I have seen a NIP Medallion 15 replacement cylinder and piston with the ball and socket joint.

TDs' always had this energetic look to them. The most energetic looking ones I was at first shocked to see was after one day going to the field and seeing my first Profi .61 engine on the nose of a Phoenix! It even lost it's prop bolt and washer the same way in the air!

It's a TD .09. The guy is VERY SHORT!
