ETA 29

[Robert Zambelli]

I'm building an Old Time Stunt plane around an ETA 29 that I found in my accumulation of stuff.

The engine is new, never run. Has anyone here had experience with this powerplant?

Reccommendations?

B T/R and B Speed engine from the late '50's. Pretty much a better built copy of the McCoy .29R. The Super Tigres and K&B Series '61 .29's pretty much put them well off the podium. It'd bring good money on eBuy. Making it work would need a venturi and some head shims. I would urge you not to do anything permanent to it, as it's pretty rare in this country, especially stock and NIB.  Steve

A new ETA 29 would bring a good price on ebay. They were meant to rev pretty hard. Probably would make a lousy stunt engine.

Only the first ones were McCoy copies, they were developed for B TR, and got very powerful after 1958. Production ceased about 1968.

Beautiful engine,

Do you have a picture of yours?

An ETA 29 was my first engine back in about '57/58 and I learned to fly (after learning how to start it) with it in a solid wing trainer. We all (3 of us kids) used the same basic design to learn with, me with the ETA, another with a McCoy 29RR and the other with a Dooling 29. None of us had any problems with our engines although we certainly weren't using the props they were designed to be used with. Fuel was just straight 3:1 all castor because we mixed it ourselves. To be honest, I think if you really wanted to use that brand new jewel in an OTS then I see no reason why it shouldn't work quite well.

In Ron Moulton's Control Line Manual mention is made of someone (Brian Brown?) making people sit up and take notice of his ETA 29 stunter on pressure feed.

But as is mentioned later in the chapter on stunt high speed was the order of the day then....

My Harry Latshaw Hustler B Proto Speed plan shows an ETA 29, it's from 1965. Harry said he had a drawer full of them and doesn't remember where they went. I'm using a Tigre.

Old vintage Aeromodeller stunt plan Hopit originally had an ETA 29 on board. The later model ETA you have the more exciting it would be!!!
I think Hopit looks as if it was influenced by a U.S. design of the time. Maybe the short Victory?

I test ran the engine today and was both surprised and pleased at how user-friendly it is.
Very easy to start and needle. What was really interesting was that it seemed to have a stunt run - like a fast four-cycle. Can't wait to try it.

I'm building an OTS plane that shows the ETA 29 on the plans.  Anyone know what it might be?

Hint: it's a British design!

I will post some pictures as soon as I get my laptop back - it's sick.

I had a deisle 15 in 1961 good running little engine.  F.A.I team race champ. It was made in england.  The cases would crack  jim

Sounds like the "Cougar" designed by Gordon Rae wingspan 52 ¼” span for ETA .29 coupled flaps with an open cockpit.

Gordon is a team race enthusiast so probably had a few spare ETA 29's.

I've posted a picture of my ETA 6 below, it's set up for Vintage B class Team Race.

They have two rings so start well hot or cold.

The Cougar looks like a beautifully simple design. I like it.
Is it OTS eligible?
Where can I get a copy of the plans?

The aircraft I'm building is not the Cougar.

Ah! A genuine ETA .29 6c, made in 1964. You've hit the jackpot!

It should be a goodin!

I'll see if I can find a source for that plan.

Looking forward to what Bob has on his building table. I would love to see some of Bob's OTS airplanes at VSC.

That Couger is also interesting. Are the flap fixed or moveable?

Bob, you mentioned a project you had in mind some time ago, I won't spill those beans and in fact I do not know it that is the same project you have in mind now.  However, what ever you are building I hope it shows off that gorgeous engine.  One really neat thing about rear intake engines is that it should be relatively easy (compared to front intake) to do things like re-time the intake port.

After seeing the Z-man fly Wankels, AUTHENTIC ignition, and all manner of 4-strokes, it seems that this is the kind of 2 stroke he would use!
