Well, no replies for instructions for an Quicky .09, so does anyone know what size prop for break-in/flying for this engine?


I little late I guess but a 7x4-7x5 should be good, as the piston and cylinder are common to the other 09 engines as far as I know.

The Enya 11CX are still being made too, and then you get ABC technology.

They show up on ebay from time to time.
But shtterman who specializes in Enya control line stuff can get the engine for you.
he has a store on Ebay. www.ebay.com/itm/ENYA-09-IV-R-C-NIB-CURRENT-MODEL-/290514256539
I had bought parts to rebuild several engines from him already myself.
You can also buy direct from Enya if you like too.

Is a pumped Enya 60XF II Al-Chro a decent engine?

No, terrible engine, not worth having, leave it alone, I wanna BID on it!

Just kidding, but if you're looking at what I saw it's actually an XF-III, it's just the instruction sheet that says XF-II. If you look carefully at the LH engine mount you can make out the III stamped there. Just for your peace of mind, I've already got one so don't really need another . Go for it, they're magnificent.

Hi,

Is a pumped Enya 60XF II Al-Chro a decent engine?

Is it a revver or a torquer?

Would the pump be likely to cause issues on an brand new engine that's been in storage for many years?

Would it power a Great Planes Escapade .61 adequately?




Enya fuel pumps are gear type mechanical fuel pumps and they do not rely upon fragile, time sensitive mylar or silicone diaphragms, as do OS and other manufacturers' pumps. Other than haviing to replace a common metric o-ring, no, it should not be problematic.

This is one of the strongest 10cc engines available and it is a revver. You might be surprised at just how much low end torque can be generated using this engine with a stretched tuned pipe.

Status: offline 		I acquired a 60's .29 TV-IV Special from an elderly gent, complete with additional high compression head, muffler assy, all paperwork and a box that still looked new. It is in very good cosmetic order, unmarked and unmolested, but the P/L fit is gone.

After 35 years I am thinking of getting back into stunt.

I emailed Ken Enya today ... two hours later ... reply, and yes, he can supply a new piston and liner set ... for under $30! Astonishing.

I have a lot of time for the engines and the people who make them. Can't wait to run it in again, the slow, patient way, using full castor lube fuel.

I got an 29-IV RC special (Model 5224) some weeks before. It was totally gummed up.
After som cleaning it appered as near new shiny engine, compression is very good too.
I only have one head, can you tell the difference of the high compression head to the normal
(in mm), I don't know what is mounted...

Kind Regards,

Holm

Status: offline 		I have two of the same 5224 .29's and when you lay both heads along side of each other (off the engine) you can see the difference in the depth of the combustion chamber. The HCH rests deeper into the liner than the LCH does.

I looked through my stuff, but I didn't find my high compression head. But a standard head goes about 2.5mm deep into the cylinder.
The high compression head is more obvious that it goes in a little more deeply.

here is a pic of a standard compression head from one of my Enya .35 engines, the pic didn't quite show the 2.5mm depth very well.

Status: offline 		The low compression head projects about 2.2mm into the cylinder while the HC head projects from 3.1 to 3.5mm depending on whether it's the plain bearing or the BB Special. The BB Special used the 3.5mm projection to give 9.5:1 compression as against 9:1 for the plain bearing. Low compression head was 7.5:1 compression.

It seems logical for it to be preferable (in that case) to use the high compression head?

Yep, I'd definitely use the high compression head and I'd think it'd just as good for fuels up to maybe 10-15% nitro (for those who like to use nitro ). One day I have to get myself one of those Specials just so I can say I've got one .

Status: online 		So I wanted to join the club, and bought this Enya 30SS (BB) engine. It is new and un-run. It came with 3 documents and what look like stickers in the original box. The casting work looks quite nice. It looks to have the airbleed carb on it, so this will be a first for me. I've only dealt with 2-needle automix carbs.



This was said to have been purchased at a hobby shop that was going out of business 5 years ago. I think it was a display piece since the outside is a little dusty.

The engine seems to be well oiled, and the bearings are silky smooth. Being that the engine isnt brand new off the shelf, I popped the head off to make sure the piston and liner are clean. I'm glad I did because I found some sort of debris stuck to the top of the piston. (there was no glow plug in it) I'll clean this out before running it. I snugged the head back down (I went light on the torque as to ensure the case doesnt get distorted) and checked the front housing screws. 3 were snug and 1 had stripped threads in the hole. I also found the supplied screws for the muffler were both bent. I want to replace the bent muffler screws and I suppose tapping the stripped hole one size bigger should be done. The bad screw is the bottom left looking at it from the front. So, my questions are: What is the size and pitch of the muffler screws and front cover screws? (They are socket head screws) Also, can anyone estimate when this engine was made?

I'm going to clean it up really nice and re-oil it and if the weather behaves, break it in sometime in the next week or two. Overall, I am really happy to have this engine. I look forward to hearing its song.

I pulled the front cover off and found some dried up crusty reddish-brown oil all over the crank and inside of the crankcase. I'm soaking some of the engine parts in fuel right now to get that dried oily slime out and seal it up.

The piston to liner fit isnt as tight as I thought it was going to be. Thats okay though, this baby is gonna run real nice. I can feel it.

I think when I get the money to do it, I'm going to order 2 kits. 1- Bridie Krafty .60 (with TT .46 power) to learn on and a Sig Kobra (SS30) to go fast with. Chances are the Kobra will stay in the box until I can fly without crashing.. Just gotta work on convincing the wife I need them.

It will get better with some running after a build up of castor lines the cylinder sleeve.
The Enya SS engines with steel sleeve and cast iron piston are designed in a way that castor forms an integral part of the operation.

I am certainly not complaining about the fit. I have some car engines that you can see light between the piston and liner at BDC with light shining through backplate (these engines are less than 2 gallons in and are asian sport engines). The Enya isnt like this. There is definitely a "snugness" to it 1/2 way towards TDC but its not one of those "so tight I need a heat gun to start it" sort of things.

I need to fix the front cover (stripped screw) and mount it on my test stand.

I have 2 SS25bbs and an SS40bb and there is no pinch at the top. They are very strong runners, and start and idle well.

Have fun,
Larsen

I am far form an expert, though I have yet to see a ringless engine with no taper in the bore. I have a fox .40 single BB from '83 that had a slight taper to it. Though it was run pretty hard before I got it, it did have a tighter fit at TDC until the wristpin clip broke and shredded the piston and liner. At the end of the day, it's going to get a nice long break-in and I'm sure this thing is going to really be a runner. I went digging through my small box of engine parts to see if I have another muffler that will fit and will be a tad quieter. I think the closest one is from said Fox .40 but I dont know if the bolt spacing is the same or not.

Anyone else know if they're supposed to have a slight taper in the bore or not?

Status: online 		Folks should keep in mind that in addition to compressing the fuel/air mix in the top of the cylinder, the engine also relies upon the piston/lower cylinder bore seal to pump air and fuel into the engine. Many an engine runs bad because the lower end seal in the crankcase has worn too much, but still has great upper end compression.

I see no advantage to tapering the top of the bore in a lapped piston/steel sleeved two-stroke glow engine.
