Here's a strong '80's Al Chrome .45 Size Engine readily available 2nd hand in RC configuration at low cost.
The example being used was only $25 on Ebay complete with baked on Castor & they regularly sell for around $40.
The Bearings were fine so the RC Carb was just changed out for stock CL parts. No other changes were made & factory muffler used with a short deflector.
Factory Venturi's and Needle Valves are readily available direct from Enya, Ebay or your preferred seller. New P&L's are still available.

An APC 12x4 Prop provided a strong Engine run with a soft break from 4 cycle when level to 2 cycle during manoeuvres. All the below runs were stable with no issues with line tension.
Being that these were also the initial flights on a Legacy ARF, it only included up to & including Horizontal Square Eights of the F2B Pattern.

I hope this info helps some other flyers. Mileage will vary based on model, fuel, line length, venturi, etc. but this may aid finding a suitable Set-Up starting point.

Run #1:
Brodak Legacy ARF on  63'3" x 0.018" Lines
5% Nitro & 24% Oil (5% Castor).  Enya #3 Plug.
Enya 8mm Venturi & Pro Needle Valve.
Zinger Narrow 12x6 Wood Prop.
Launch approx 8,000RPM ==> steady but slow 2-2-2 with 5.7s laps.
6m30s Flight Time with 5.5Oz Uniflow Tank

Run #2:
Brodak Legacy ARF on  63'3" x 0.018" Lines
5% Nitro & 24% Oil (5% Castor).  Enya #3 Plug.
Enya 8mm Venturi & Pro Needle Valve (same setting as #1)
APC 12 x 4 Glass Filled Prop.
Launch approx 10,750RPM ==> fast 2-2-2 with 5.18s laps.
6m32s Flight Time with 5.5Oz Uniflow Tank

Run #3: ** Preferred set-up so far **
Brodak Legacy ARF on  63'3" x 0.018" Lines
5% Nitro & 24% Oil (5% Castor).  Enya #3 Plug.
Enya 8mm Venturi & Pro Needle Valve
APC 12 x 4 Glass Filled Prop.

Next flights will use Run #3's basic set-up with the full F2B Pattern. Will try to take some video.

The 45CX shares the same Crankcase dimensions as the Enya 45CXL, 50CX and 61CX/L Engines, so for a mid size Stunter set-up to suit this same case there are plenty of options.
The Enya SS40/45/50 mount dimensions are also close enough to allow swapping, but the SS Engines are a little shorter from Mount holes to Prop. I'll progressively list set-ups for each using the Legacy.

Steve,

Dealing direct with Enya is not a chore.

The service is always quick, and accurate. If any of your order is not available they'll email you with the details.

Postage rates are also good.

Last time I checked their website, they still offered a good range of engines in many classes.

Greg, you're probably looking at the "Catalog" section, which shows lots of great stuff, almost none of which is currently available. Check out "Shopping" instead, for what you can actually buy - slim pickings, sadly.   
I agree that they're a pleasure to do business with, though.

Do let us know how you get on with that 61, Richard. I'm finally thinking about doing something with mine, and very interested in setups, fuel requirements, etc.

Steve

"Hope this helps Steve - what are you considering building for the Enya 61?"

Probably no Enya .61RE in my future. Got .46VF, PA .51 and a couple RO-Jett .76. I'm flying the VF, have flown the PA for a couple seasons, but could use some RO-Jett .76 setup info! I was really more into the .45CX, thinking it might be a real good donk for Profile or a large Classic. Not that I don't have some options for those, too...   Steve

I think he meant me.  There's not enough room for all the Steves round here, so I want you gone, Helmick.   

Richard, I'm actually drawing up something myself. Vaguely jet-styled, Vectorish wing, about 660 sq.in. Might be a while before it appears though, so don't hold your breath.

Probably right. Hey, don't make me come down there (again)! But I've got my passport, in case some sponsorship appears.  Steve

Hi Steve (H) - Sorry, can't help with the Ro-Jett .76 setup, but I'm pretty sure one of our club members has been trimming one out in a new model so will find out where he's up to & send you some details.
Hi Steve (T) - Glad you've got plans (no pun intended) for your 61CXLS. Bring along your scratchings to the next Event so we can have a look

Fortunately since Saturday there's been some tamer weather so I have put in a few more flights where wind wasn't an issue.
RPM was progressively increased to find a happier airspeed for the Legacy & guage Engine reaction.
The Enya must also be close to broken-in as single back-flip starts are now easy & the full 5.5Oz tank is giving around 7m30s flight time.

Launching at 10,450RPM unleashed a whole new level of power & at this RPM the Engine was still 4 stroking in level flight & up into manoeuvres as switching to a 2 stroke remained soft & late.
Tight corners were no problem with the resultant airspeed, however laps were 4.8s…..need those longer lines.
From some quick calculations a set of new lines around 69' are in order. I'll then be testing larger Venturi's of 7.8 & 8.0mm & a 13x4 Prop.

With the longer lines the 45CX & 50CX Engines will then each have another set of tests - both these Engines had plenty more power not realised.

Thanks for clarifying Tim, that's right. Eyelet to Eyelet the Lines must be no more than 67' 5" on this Legacy to satisfy the FAI regs (max 21.5m Centre to Centre).

The Prop Centre-line to lead-out eyelets & Handle Grip centre-line to eyelet take up 2'10.5" of the allowable measure, connectors then take 3". The new set of lines will be closer to 66' Eyelet to Eyelet.

Had a couple of flights today using the new set of 66' Lines (eyelet to eyelet) this time using an APC 13x4 Prop:

Launching the 61CXL at 10,250RPM was still too quick with 4.9s laps.
Launching at 10,050RPM resulted in 5.4s laps with better switching so I flew the full F2B pattern with a flight time of 8m on the 5.5oz's of fuel. Surprisingly frugal!
The 13" Prop is a little long for flying off grass (tips are now green ), so will look for some larger wheels - all our fields are grass.

Next flights will be practise for a local contest early December. After that the 45CX then 50CX can be re-fitted - should work well with an APC 12x4 on the longer lines.

Falcon 13-4 is a good prop for Enya61CXL, that's what I'm using in my SV-11.

Don't have a 45 CX but am enjoying reading about your experiences with the 61. I have only bench run mine but have been impressed with the results so far. 

I tried the swirl venturi on a 45SS. Found it hard to set the NV prior to launch as once in the air the engine would accelerate and go faster than I wanted it to. More rat race than stunt run. I'm guessing it was because of the "ram air" effect of the swirls...or something like that. Curious as to how it works for you.  

Thanks Steve - Being this time of year there were quite a few other regulars who didn't make it either. I missed the November Comp day for like reasons.

Balsa Butcher - Thanks for sharing your experience with a Swirl type Venturi. When I can get back to the field I'll take a regular 7.5mm Venturi for comparison using same NVA setting etc.

I got muffler and adapter (required) direct from Enya.

The 61CXL-S shown has the matching Enya Adaptor & Muffler that was ordered direct from the factory with the Engine. These fit the 45CXL as well. Available from Kaz, Shtterman (Ebay) and direct from Enya.

I've now managed 3 flights with the 7.3mm swirl type Venturi & APC 12x4 Prop & found it more difficult to prime the Engine due to the swirl edges not sealing well against a fingertip.
I also experienced the same difficulty getting a stable launch RPM. On the 1st flight launching @ ~10,250 & the Engine spooled way up like Balsa Butcher's experience. Fast 5s laps..
For the 2nd & 3rd Flights it launched at 10,000 - 10,050 RPM and it didn't seem to spool up at all compared to the normal type Venturi, resulting in slow 5.7 - 5.8s laps that made even a Wingover difficult..
Unfortunately there was not time to try & achieve a mid point RPM or swap Venturi's for direct comparison, however shall try that & then a normal 7.5mm Venturi on next trip to the Field.

Falcon Prop's Australian Distributor is based in Sydney, so there's now a couple of 13x4 props inbound for testing with the 61

I think you're gonna like that Falcon.  Let us know how it goes.

Does anyone one have a working email address for Enya?

Hello,
I am just renovating an Enya 45X, and going to try it for stunt. This is a different beast to the 45CX as far as I can see. It has a dykes ring and is suffering from a lot of blow by (dark stains on the piston sides and even on the crank!
The model number on the case is 6101 and is a schnurle (Sp?) ported engine. I was wondering if the 45CX piston and cylinder is a drop in replacement? anyone know?

Andrew.

Hi Andrew

As far as I know, the Enya 45X never come out as ring engine. I have 2 and they are AAC. Perhaps you got a 45X with a 40X P/L?

The 45CX p/l will not fit and it is not available from Enya. The 45X AAC P/L however I think is available from Enya.

I never test flown one but I am sure the Enya 45X AAC will work quite nicely in a C/L model with a 11~12 x 4~6 prop and 7.0~8.5mm venturi (depends on alt., nitro, drag, weight....).  

Martin

Hi Andrew,

The 40X has a stroke of 18.9mm against the 45CX's 20.4mm. There was however a 40CX version with the same bore & stroke as the 40X - see attached manual covering the 40CX & 45CX models.

It may still be worth an email to Ken Enya to find out whether a 40CX04 Piston & Liner Set will fit the 40X Case & if there's stock available.

Cheers,
Richard Field

Thanks Richard,
I will do as you suggest, no harm in asking Ken if he has stocks and if it fits!

Thanks,

Andrew.
