Precision Eagle 5.8 GLOW to Gas possible????
Hi Guys,
I have a Precision Eagle 5.8 In a Sky Aviation Mustang I purchased about 8 years ago, I finally decided to pull it down off my hanger wall and get it ready for flight. To my surprise, its set up for glow.
Can this be changes over to gas? If not, what fuel would I burn? % nitro?
I'm shocked its a glow motor. I was certain it was a gas motor. I never hear of a glow motor this large. But then again, I'm not into racing planes either.
What was the advantage?
Thanks for any advice..

More power and speed....
Gas 87 octane and 32or 40-1 good oil
And sometimes a different carb, a good glow conversion would have made the carb unuseable with gas...

Hopefully, the glow motor was stored with some after-run oil in it. Otherwise, you may have some rusted needle bearings on the rod. Glow fuel is fairly corrosive to steel. Gasoline + oil protects steel from rust. No special protection is needed for engine storage when running gas.

thanks guy, but am I to understand they can be converted to gas? Do In need a new carb? What would I need to do about the spark plug. I has 2 glow plugs on it now. I don't think this engine was ever run.
Thanks again for taking the time to help

Take out one of the adapters and use an NGK BPMR6F witn a new RC EXL ignition....Leave the glow plug in the 1/4-32 hole...
The carb is probably a Walbro SDC 80....If it has been converted for glow fuel the internal passages are too large...

I dont know anything on that engine but any glow engine can be converted into gas.(With glow type 2 needle carb.I dont think a Walbro type carb can work). One will need a CD type elec. ignition set and such a gas pump to supply gas to carb.
NGH gas pump.Ask to http://www.agaperacingandhobby.com/ for it.

Looks like NGH has cloned the Cline regulator, which is functionally the same as the Walbro pump part of every Walbro carb...The walbro WT499 carb will work with most small gassers for glow fuel...Other Walbros will work if the inlet needle hole is drilled out to about .083 and all small fuel passages are drilled to double the AREA, not the diameter...
Walbro diaphragms will work with glow fuel, we have been doing this for 25 years...
The original application for the 499 carb must have been a very thirst gasser, it's already large enough for methanol....

Don't forget to remove the glow element from the glow plug. Put the magnet in the outer rear of the prop hub and simple mount for the sensor. Will need a new carb too.
