Enya 4 stroke engines

This is just curiosity. Has anyone had experience with the Enya 53 4 stroke or the Enya 80 4 stroke? I like the idea that the pushrods are on the back of the engine. After recently putting a Saito into the ground nose first, I've thought about that. The Saito came out fine, but the ground was soft.

Any idea on weight or power compared to the Saitos?

Hmm, I guess no one has tried it.

I have ran a Enya 53 in a R/C ship and it is a good running and powerful motor.A friend has a 80 but it has never seen fuel.The 53 is fairly light also .I do not have the weight but I think it was a hair lighter than the Saito 50 and turned up a few more RPM.Dennis

Randy:

I know that Bob Zambelli tried and liked an Enya .53 on several models....most notably Winfred's 80+ oz., draggy "RED BARON"...... everyone who flew the plane thought it terrific, and the Enya had replaced a pretty strong running ST-60!

I believe that weight vs. the Saito lineup is a drawback....

Dennis Toth has had success with the .53, too, I believe?

See Ya

Enya/Altech also has a very good repair service. I sent an Enya 46 F/S in for repair and they only charged me for the parts. And did a real nice job.

Hi Randy,

I ran the Enya .46 on the Imitation for about two full years and liked it very much. Even built the silver, red, white and blue CITATION V for it. Ended up not doing so for reasons that (retrospectively) had more to do with my lack of understanding of props in those days (this airplane eventually won the Nats in 1986 powered by an ST .46 so that will give an idea of the time frame...didn't even own a prop pitch gauge in those days).

Final straw that killed my interest at that time was the rusting away of the bearings over a winter hanging on the wall. I think most four strokes now have stainless bearings (or something) that resist the problem of the hygroscopic nature of the raw fuel that remains in the crankcase.

I think the .53 (built on the same case as the .46 near as I can tell) would be a fine engine to develop.

I picked up an Enya 53 a few months ago. I was actually looking for a Saito 56, but I got an excellent deal on the Enya. Weight is not an issue. As you can see, It weighs 14.1 oz. with a C/L vebturi.
Saito lists the 56 at 14.5 oz if memory serves me correctly. I would guess that after removing the carb and and setting it up for C/L, the weight would be the same.
Two things that I do not like about this engine is the forward slanting glow plug (can't use my regular glow clip) and the intake manifold arangement. The intake tubing is a press fit into a surgical tubing sleeve in the cylinder head. I had to make a retaining strap to hold it against the cam cover so it doesn't move around or fall off in flight. Other than that, it's a good engine, lots of power, easy to start.

Thanks guys. I have a chance to pick one up pretty cheap and wondered if it was worth the effort. A guy in the local R/C club has a 53 and an 80. The 80 is NIB and the 53 has probably 25 flights on it. He's decided to build ridiculous scale planes and is unloading most of his "small" stuff.

What would the .53 4 stroke compare to in a regular 2 stroke? I wished someone had a comparison chart or something.

Randy - we've done considerably testing with the ENYA .46 and .53 (none with the .80). The .53 is very close in performance to the SAITO .56 but a tad more temperamental to set (needle). The .46 is awsome - It will quite adequately replace anything in the .45 - to .50 2 stroke range. We replaced an ST .46 with one and had to go to bigger (.018") and longer (68 ft) lines on a Stilleto.
The rear pushrods cause one minor problem - the glow plug now faces forward so we need to be extra carefull with the electrical connection.
The ENYA has two cams which can be set for opposite prop rotation. The newer ones also feature stainless steel bearings and a crash warranteee (not that we ever crash!).
