If they're selling that cheap I'll just keep mine and make a plane for it. James, does yours have the single bolt lug in the exhaust? The one I have does, I wonder what muffler fits it. What size is the venturi? What airplanes, lines, props and fuel would be good for an Enya .09? MM
MM, I recall gcb mentioning in Brotherhood of the Ring of his Enya .09 powered Ringmaster Jr. He was flying on 42 foot lines. I don't remember if it was the III or IV. Sceptre Flight has Peter Chinn's engine article on the III.
http://sceptreflight.com/Model%20Engine%20Tests/Enya%2009-III%20CL%20&%2009-III%20RC.htmlIt speaks of both CL/FF and RC versions.
Regarding Chancey Chorney's photo, looks like an earlier Enya .09, may be the II.
http://sceptreflight.com/Model%20Engine%20Tests/Enya%2009-II%20RC.htmlRC version has a touch less HP at 0.118 at 12,750 RPM whereas the III TV RC version is 0.16 HP at 14,500 RPM. The CL III has more power, uses a venturi insert that can be removed for even more power as the article states. RC carb mounts right on top of the non-removable CL venturi.
I've flown the Enya .09-III TV on RC with Tatone 09-19 Peacepipe muffler on an old 41" wingspan Hobby Shack Cessna 180 ARF foamie originally for .049 reed valve. Was a definite upgrade, really moves out on a 7x6 wood T/F prop on 15% nitro glow fuel with 25% oil. Found that needle settings were less critical with lower inertia wood props. Don't know if that might be related to the muffler I'm using, as I don't have the OEM muffler.
The threaded hole in the middle of the exhaust port is for the baffle plate linked to carb for the RC version, to give it a more reliable idle by providing back pressure if muffler is not used.
Got a couple CL version .09-III's, but been dragging my feet in getting their airframes completed, so have nothing to report there.
