Hello; I have had some experience with Enya engines; I have 2 46's, and have had a 53 and a 120r, but I sold them to people who are still very happy with them. The 46s are a bit of a different story; one of them I bought from cf-drg, it is a great engine, I flew it in a Dynaflite Mustang for 6 or so years, no problem whatsoever. The other one wouldn't run over 8000 rpms no matter what prop was on it. I took it apart many times trying to find the problem. I finally stumbled on the problem when I measured the cam bushings, they showed .004 ovality, no wear on the cams themselves. After nearly a year of searching for parts, I found a replacement cam chest in England. Now it turns a 11 x 7 9800rpms.

A fellow flier at our field recently bought a pile of Enyas (90, 80,53, and a bunch of two strokes) the first flight with the new 90, the muffler came off eating the female threads on teh muffler. Also there is the learning curve with the unusual carb.

The 53 I had never ran properly, after I sold it the fellow who bought it took the cam chest off and found that the cam idler bearing in the cam chest was cocked. He made a tool to estract it and pressed it in properly. He tells me that it purrs now, but I haven't seen that engine in a plane yet. so between the two I guess you could say that I haven't been too impressed with them.

If you ever need parts or service forget Altech, they aren't interested in helping at all. They don't mind selling them but if you wnat more then that you have to go to Steve Webb in England.

Oh yes. I have one of those lovely open-rocker 40s too.
