I've come into possession of an Enya .60, Model 7032, and wonder if it might be a reasonable powerplant for something OTS like a Wildman or even a Stuntwagon. I did a search and found that Mike Donovan used one on a Humongous. It's a ringed engine. Anyone else have any experience with this engine?

Hi Gary; I flew one in R/C pattern for several years, but know nothing about how they would work control line. They are a baffle piston engine and as I remember did a nice 2-4 break when flying R/C. Back in my early days of R/C we use to run our engines much like we do in control line. Maybe someone else with more experience will chime in.

I haven't used the 60 but I've used the similar 45 model 6001 extensively which is brilliant. There were two versions of the 7032 though (called the 60-II) and was Enya's first engine to use a ringed alloy piston. The first version had chrome plated castings(!) then went to the normal surface finish but with internal changes like skirt ports in the piston and a thicker piston crown. RC versions had the exhaust port drilled on the sides for a rotating baffle and later baffles had a slightly larger (1/8") hole to improve idling. CL versions had undrilled exhaust. The 7032 was made from '65 to '69.

Not with the 7032. I did have a 7033 (Enya III) in a Strega that flew great, but pulled like a horse! Did an excellent stunt run.
Had an interesting experience with it in Woodland on a hot day. I was priming it and while flipping it over it started without the battery.... Luckily I didn't have my finger in the prop arc.
And the parts are NOT interchangeable. (7032-7033)
Good luck, Jerry

I had a 7032 for awhile. Only bench ran it. It was heavy and would turn a large prop in a solid 4 stroke. The deal breaker was that it was timed to do so at a very low RPM, in the high 6 to low 7,000 rpm range. That could be made to work but was to slow for me.
Tried, and still have a 7033 (later) version. I think I bought it after seeing Jerry's run at Woodland. It seems to be timed higher and runs very much like a ST-60. That's the one I would look for but still may be too heavy for the planes you mention. Other's mileage may vary. 8)

The late Dick Wolsey from the Boston area used an Enya 7032 in several stunters. Ran very well in a traditional 4/2/4 style. Used about a .295 venturi, adjusted break with head shims, and used an Adamisin/Brodak style muffler. VERY similar to the ST 60, but smoother run character. Dick liked 13/5 and 13/6 props on the Enya as I recall. Dick was competitive in Advanced with this set-up. Miss ya, Dick...

I have one put aside for use in a Rabe Bearcat in the (probably distant) future.

I have an Enya 7033 on a 900 square inch Magician that Pat King kits. it is a perfect match.

Thanks for all your input. Not a lot of experience, but sounds like it might be worth a try.
