Enya 29-V 5225

I am in no way an expert on Enya's, the singer or the engines, but I do very much enjoy both. If you don't feel like you got  your money's worth on a never run $10 engine......I'd be happy to double your money for you! Hehehe
Just wait for Bob to check in, he'll tell you what a nice engine you have for sure. Congrats on such a super swap meet find.

These were popular with the team race crowd. I do know the .35 5225 came with two heads, a high compression and a low. They were not very friendly for control line stunt. They needed to be somewhat detuned. Ken

Nice find Larry and I'm a little jealous not having a 5225 in a .29. Got the .35 5225 though. Check this link out, it will tell you everything you want to know about your new engine.

My first Enya and "big boy engine" was an Enya .29 T/V mounted and flown on my Sterling Fledging back in the 1980's. Still have it and it's still on the same airplane.

Of all my Enya's (over 100) the .29 is the most difficult to find in any condition, you are very lucky. In it's day the .29 and .35's were the most popular C/L engines and usually were ran hard and put away wet.

The earliest .29 was the sand cast red heads of the early 1950's and are rare as hen's teeth. Second are the "airfoil" Enyas when they moved to die casting them. The four Enya brothers have been involved in model aviation since the 1930's.

Attached some pictures.

Unless any engine is completely unusable or unrepairable, it's gotta be worth $10. I'm assuming this is the round venturi type, not the square. The .29 & .35 square port engines were supposedly excellent stunt engines. There is no difference (according to Ken Enya) in the porting & timing of these engines between the RC & CL versions, But as Ken mentioned, there were 2 heads available. It'll be hard to know what head you have, but what's that matter? Heck, it's still a $10 new engine. My $5 Enya .15 I got a couple of weeks ago was probably only 1 flight (and crash) old. Don't you just love a bargain?

Thanks for the replies guys .... nice collection rsv1cox!!  I knew there was at least one Enya fanatic around here ....

Already got together with Jim Lee .... after a couple of emails back and forth, it was determined that the venturi opening is the same as a .35 .... round and .475.  He's turning up venturi's for FP's now (Good ... I need one for the 25FP I got too!) and he'll turn one for the 29-V and put in an ST needle.

You guys deserve some pictures, so here are a few.

I'm not sure whats all over the carb .... it has the outward appearance of being run.  But the inside is telling me a different story.  

Took pictures the best I could .... also, take note of the mounting lugs.  Not a mark on 'em.

Yup ....paid only $10 for this engine.  $20 for the 25FP .... I'm psyched ...

That's dried castor Larry, I would know it anywhere, I have seen similar Enya's like that over and over.

The mounts are clean and are an indicator, but I would guess that it had been run at least once.  Pull the plug and the head and check for combuston.  

The cylinder fins on these never seem to collect a lot of burned on castor, the heads are a different story.  I relieve the head screws the same as I tighten them, a tiny amount first in a criss-cross pattern.  When tightening them I put my thumb right over the glow plug opening then pushing down just barely snug them up, again criss/cross.  How tight? You know it when you feel it, nothing ham handed necessary here, but you already know all of this.  

My latest buy.  An Enya .09 minus carburetor for $3.50 ebay.  





Looks like this now:





Boiled it in anti freeze this morning sandblasted the case this afternoon and rubbed it out with 0000 steel wool and oil.  Comes out like factory.  I had a new angled needle carburetor on hand.

Bob

BTW, I'm trying to believe that maybe someone sprayed it with WD-40 (hate the stuff) or some other substance that dried on the surface. Pull the head and see, but I have seen clean cylinders and heads too on engines that I know had been ran.

Regardless, that's a heck of an engine and a heck of a buy, I would love to own it but Marleysky beat me to it...

Wow .... thats a really nice clean up job. It's ready for a display case, eh?

Yeah, it certainly looks like dried castor ... but it seems to be the only spot. I'll pull the head off and have a look see. I'm pretty curious myself. When I pulled the plug out and looked through the hole .... the top of the piston looks clean. Couldn't get a good picture of that tho ....

I'll make it look all nice and pretty when I get the venturi .... eventually it will get run in something. I'm not one to collect, so it will fly someday.

Pics to come soon ....

Popped the head off .... I think I need to treat this as in new condition.

Only one head shim, if that tells you anything.

I'm beginning to think maybe someone swapped carb assy's.

Yes, that is pretty righteous especially around the top rim where the carbon really builds up. I would say that you have a low time/no time engine there.

Maybe some rookie fueled it up, didn't have a fully charged battery and couldn't get it to run.

Try removing the idle set screw on the top of the carburetor and pulling the cylinder straight out. It looks a little gummy. If it won't come out easily it's gunked up with castor.

You can use fuel to clean it up, but I use warm Simple Green on the easy stuff, warm water rinse, compressed air blow-out and a final rinse in alcohol. Then after run oil on reassembly.

I don't believe the Enyas use a head shim at all. Are you sure?

Yup, I'm sure. I took it out to see how many there were.

Enya refers to it as a gasket. I have never seen more than one. I wouldn't really call it a shim.

I have seen them really mangled up, but usually they are difficult to remove without damage. I generally leave them in place. Enya supplies or makes available high and low compression heads for some of their engines.

Ahhhh ... OK. Gasket it is ... This one popped right out and was actually quite thick.

Gasket ... I'll remember that ...

Nope, never seen one in any Enya I've dismantled.

Next time you have one apart Rod look closely around the heads chamber, it really just blends in.

The reason I pointed out that Enya refers to it as a gasket, if Larry searchs "shim" for a replacement it will never show up.

Heres a pic with the gasket removed ..... it is exactly .020 thick

Well that's a new one on me. Must just be on the larger engines. There is no gasket listed on the Enya web site for the smaller engines. I have a .60 but have never dismantled it 'cos it's new. Next one down is a .35. Fully stripped and cleaned that and don't recall a gasket. Other than that I have .19s, .15s & .09s. I'm positive they don't.

They are there Rod, but you really have to look for them.  Head gaskets are not listed on the parts lists that came with the engines, but they are supplied already installed with replacement heads.  





You can dig them out with a sharp pick, but as mentioned I generally leave them in place. I have found a few that were so mangled probably by an inquisitive previous owner that they just fell out.

My Enya .29 is a 5224 and came with two heads. Do you suppose the gasket was added to replace the need for the second head?

  not the first one the second one Old Shoe string with a Enya 29 on it came with two heads and was a bear to get started back when I was in my teens // probably the wrong fuel and no elec. starter , I don't think its completely broken in never been in the air and now broken and needs repairs . Bell crank pulled out silk well gone fin broke off , man moving really takes a toll on planes Never had the engine apart but when I go to fix it I will have to and ck. the running also . Its upstairs or I would tell you the series , getback sometime !!

Just to clarify, the V series .29's and .35's were the only ones to be fitted with head gaskets, according to Bob Allan removable for a higher compresson ratio. Prior .29/.35's were supplied with high and low compresson heads. Enya intended the .29 to be their speed engine, the .35 stunt.

I have a .35-V TV, can't remember exactly when I picked it up, but I think I purchased it from America's Hobby Center on sale in the late 1970's. I purchased a Kavan aftermarket universal muffler and specific adapter for it, think from Ace R/C. Ace used to have a catalogue of various engine and R/C items from other manufacturers to include Kavan. My grey matter is getting fuzzy for stuff occurring 40 years ago.



I haven't put it to use yet, have also a .35-III TV, which is already broke in, targeted for my Goldberg Falcon III. I've bench run both, and they both seem to sweet engines, a touch more powerful than my Testors McCoy .35 Red Head. I don't own a tach, so I can't give qualitative data.

Neat engine George, and I don't recall ever seeing that muffler. Very stylish with a bullet nose and polished ends.

And Eric, Yes. The 29's and 35's that came with two heads did not have gaskets. Later, according to Bob Allan Enya in an ecomony move that lessened the price to the consumer added a removable gasket so you could take it out and increase compression. A gasket being less expensive to manufacture than a second head.

Works for me.
