Hi Dennis,

The 49X is very similar to the actual Enya SS50, same bore and stroke. I just not sure about the timing, but it is probably the same.

The Enya 49X with venturi is lighter then a ST G51, so weight is good for C/L. As matter of fact there are many Enya engines that are very light, if not the lightest in it's class. Some how people got stuck with this idea that Enya engines are heavy, when it is the other way around....try to beat the weight of a Enya 40XZ , 61CX or SS50. I also just got an Enya 45CXL Rear Exhaust and it weighs a lot less then a OS 46VF.

This engine will work best with low pitch props, 12x4 to 13x4. A friend is using an Enya SS50 with 8.0mm venturi, stock muffler, 3 blade 12.5x3.75 carbon prop on a 65Oz a .60 size model. Launch it 9800rpm, laps 5.2s and it does a 4-2-4.

This is a video made last year when we started using the Enya SS50. Its all stock and we used an air filter to restrict the venturi. The tank height was not right,  it got much better run symmetry once the tank height was adjusted.



And here is a video of an Enya 61CX

The notorious Englishman with the super Hawk used 40 CX s ,.29 ? Venturie .
Filed early lighter muffler to fit , or filed engine .

Engine Test timing figures show 49 to be conservativer than 40/45 on sleeve
so theoritically tourqueier .

He filed lug hole slotted to interchange with earlier motor, Info was in
Aviation Modellor international, 1980s . May be info on CLAPA or Dave Day sites.

 I also just got an Enya 45CXL Rear Exhaust and it weighs a lot less then a OS 46VF.

45CXL,  what is that, an older model RC engine ?

Hi Dennis,

Macs Products has a header for  49X.  http://www.macspro.com/headers_side.asp

Look for Headers .35-.555 PN  2420, 2421,   2422 and 2423

You can mount the engine at .45 like Igor Burger has done and use a pipe with it.


Or you can make a header muffler. I made a header muffler for an Enya 61CX RE attaching a deflector with JB Weld. The JB weld does not stick to the deflector but it will hold the deflector in place and do a pretty good job sealing the gases. It has been working for a while now.

Martin. Thanks for the ideas but it is easier to mill an adaptor plate for a current tongue or Big Art muffler. I don't run pipes yet since I only used them before for a performance boost. However, I'm getting ready to try one soon. I assume that the 45 RE is a new offering from Enya.

I'm pretty sure one was used by Bill Simons on his Rogue at the Nats. What, early 80s some time?

  Bobby would know, but my rapidly-fading memory tells me this one of of the many "schneurle wars"/"greatest engine ever this month" engines from that time frame. But other than that I don't know anything about it.

Hi Dennis,

From what I understand  just a very few of the 45CXL R.E  landed in the US market back then. It has a price tag of U$179,99  probably a lot more expensive then the OS 40/46VF at the time.

The Flying Models article mentions the Enya 49 being used in 1981.

And a switchover to the ST 60 in 1982 ... along with 10 ounce tanks and 15 inch props. 

Which fits in with my memories as a kid - pretty much all the New Jersey-based flyers switched over from the various schneurles and the ST 46 to the ST 60 in 1982-1983.
