Default Enya 29/35

Just to pass on something I found out about over on SSW.
Enya have reintroduced the early square venturi 29-IV and 35-III engines at very reasonable prices. They come with the usual 3 venturis but only the one cylinder head.

If you have any used ones it might be an idea to start selling them and make a killing before the word gets out too far .

Yes, that's about $63 US for the .35. I have one BB R/C, and one sleeve bearing R/C. BTW, they both came with the spare cylinder heads.
Both are 70's vintage, I think. Would be nice if I could convert one to the C/L configuration. Looks like the Enya site has the venturi and spraybar assy. available also.

Over on SSW it took 6 days from the first post that they were available to being sold out. Maybe Enya were testing the waters to find out the level of interest? If so, they sure found out . Some were wondering if Enya had just put together as many as possible from their old spares but I find that unlikely going by the 60-IIIB I bought recently which has a different crankcase to the original (new way of mounting the muffler).

Anyone buying or running these engines needs to understand that those are iron/steel engines and many (but not all) Enyas were set up tight and needed an extensive break-in. Also, the fuel should contain half or all castor lube of 20%-25%.

They are not plug and play like the modern engines. The Enya instructions say no break-in is needed, just run it a bit rich for awhile. I prefer to do initial breakin on a bench. Once broken-in, they will last a looong time.

I like Enya engines a lot. Just bear in mind that some models need a little different handling than ABC.

George

Update: I understand that they are back in stock again!

Yes, they are most definitely back in stock. I just bought a 35-III

The little plain bearing .09 for $38 looks attractive too.

The .35's are sold out again, and there's only one .29 left ;->

I just noticed something remarkable - according to the Enya web site, 7 of their top 10 selling products are control line engines!

http://www.enya-engine.com/store/ind...=index&cPath=1

Enya top ten sellers: (C/L engines in bold)

Bestsellers
1. 35-III
2. 61CXS PRO.
3. 20S
4. 29-IV

5. 40XZ TN
6. 41-4CD TN
7. SS15DBB S
8. 61CX TN
9. SS30S
10. 09-IVBB


Looks like C/Lers are getting behind Enya's direct sales channel in a big way.

cheers,
Colin

I love those things, apparently they can turn props from 7x4 to 10x3.5. I have run them with the 7x4 and 7x6 sizes, never thought of trying anything bigger. Next time I build a 1.5 sized model I might play around with that. You can't kill them with a stick either.

Good, maybe we can convince Ken Enya to bring back the original 45-1 6001, the stunt version.

Agreed Luke....I think Enya made a mistake bringing back the model 6002 because it's no where near as good for stunt as the previous one and the RC guys aren't going to be interested in it.

Default RE: Enya 29/35

I have asked this question over on SSW, no harm in asking here.

What are you all running your Enya 29/35's on ?

I have a 29 and 35, old engines well run in with the standard comp head (low) andI have been running them on meth/castor 80/20. The hotter the plug I try the worse the run, i.e. rough, so I have gone to using a Taipan Blue plug which is similar to the OS A5. In fact I have tried both plugs and the Taipan seems to be marginally better. If I go to a hotter plug the engines become rougher running and there is a noticable drop in rpm when the battery is removed, in fact the Fox std plug simply cuts out.

Conventional wisdom suggests I should be running a hot plug with such a cold fuel but the reverse seems to apply here. Both engines run best with the cold plugs but I feel I could improve on the run with a better fuel/plug choice. The fuel is fresh BTW. Higher oil content makes the matter worse.

Luke.

5% nitro, 28-30% oil and a Fox std long worked fine in my .29. It was a fuel I made by dosing up some common synth blend stuff with extra castor. Never tried it with 0% nitro...

OK, cool bananas,

I have just run the Enya 35 III on 10% nitro, 20% all castor with an OS #8 plug. Excellent run, not the slightest problem. No FAI fuel for the Enya 29/35 it seems. They want nitro . Bizarre, I run my Fox 35's and OS 35-s with zero nitro without a hitch. Perhaps the timing of the Enya's is more aggressive. I ran these Enyas years ago was never quite happy with the way they ran, hence the search for a better plug/fuel.

Back when I was in high school I put dozens of hours on my OS MAX-S .35 using the cheapest available fuel - 80% methanol / 20% castor, without a problem. 80/20 fuel, OS #3 plug, MA 10x6 was golden combination for my .35. Of course I didn't fly Enyas back then, they were not easily obtained in Toowoomba. My MAX-S .35 was actually a substitute for a Christmas time request for an Enya .35, but my grandfather couldn't find one so got me the OS instead.

More recently I have been playing with some 2nd hand Enyas from eBay, and got excellent runs with 5% nitro and an Enya #3 plug. That was smaller ones though.

I have yet to run in my brand new .29-IV which I bought last week.

If Enya were to produce the model 6001 again, I'd certainly be interested in buying one. Speaking of the bigger Enyas, can anyone who has run both talk about the pros & cons of the .60-IIIB vs. the new 61CX-S Pro ?

cheers,
Colin

I have sent Ken Enya an email congratulating him on the re-issue of the 29 and 35 and asking to let me know if he ever decides to re-issue the 45-I 6001, also sublty mentioning that it was the best stunt engine going. Who knows, if he gets enough feedback then it could be a possiblity.

Default RE: Enya 29/35

I am quite sure you are right the timing on the old Enya 35's is more radical than the Foxes, OS Max's etc. Many long years ago I was running Enya 29-3 model 5103's in slow combat. I purchased these engines in the USAF base hobby shop in Misawa Japan in 1957 ($4.00 each). The engines were faster by far than the Fox 35's and OS-35's on the same airframe. They were not as good for Stunt as the OS 35's or Fox 35's. I still have all four of the engines and two of them have at least 500++++ flights on them. I still fly them occ.. If I remember correctly they seemed to like 15% Nitro and 22% Castor Oil best. The #2 Venturi gave the best all around performance, the #3 would not pull well through tight turns. I used "Veco" "Tom-Tom's" covered in silk and dope, with no landing gear for my slow combat ships. The kits were about $3.00 each, the silk was $0.25 a yard ($.035 a yard for colors), the "Clear Dope" and thinner was available from the USAF stocks, sold through the Base Hobby Shop very cheaply. Of course Ambroid was used to put everything together.

As a follow up, I plan on using one of the Enya 29-3's as the power source for my "Glo" Class "B" SAM Radio Assist Old timer. I'll use the #3 Venturi 15% Nitro 22% Caster under pressure, with a "Formost" mixture control to shut the fuel off at 23 Sec. The old Enya Control Line engines were quite amazing, as I expect to be competitive 50 years later. Modern engines develop more power, but the Enya is Very light, and the 5 sec. additional run time over "Sch. Port" engines make a difference.

Default RE: Enya 29/35

For those that are wondering about the timings here are some figures I've collected on my own engines. I'll list the figures as exhaust open BBDC, transfer open BBDC, inlet open ABDC and inlet close ATDC.

Enya 35 model 5224 #1 (round venturi)
60...50...33...43

Enya 35 model 5224 #2 (round venturi)
65...55...31...45

Enya 35 BB model 5224 (square venturi)
64...52...35...50

OS Max-S 35
63...56...45...40

Fox 35
67...55...45...40

Merco 35
65...55...43...43

So the Fox 35 has the most radical cylinder timing but shares the honours with the OS as having the mildest crankshaft timing.

Downunder,

Thanks for the timing info. My guess is the Enya 29's of various models have a combination of radical port timing and crank inlet timing.

Ralph,

I agree with you in regards to the Enya 29. A very strong engine for it's size. They haul!



Thanks for the figures Downunder. Let me know what you find re the running of the Enya 35 on 0% nitro, when you have the time that is. No rush.
