Glow to gas
 

Where do I find how to convert from glow to gas? I want to convert a 60 glow to gas.

RE: Glow to gas
 

that may be a bit small for gas...


which plane?

RE: Glow to gas
 

Are you talking about converting the existing glow engine to run on gasoline or putting a new gasoline engine on the airplane?

RE: Glow to gas
 

A 17cc gas engine may work, but it depends upon the plane.

Some gas engines like the smaller Evolution engines will actually mount into a standard glow engine mount. These are the easiest to deal with.

However be aware that an unknown degree of "reworking" may be required to make everything fit...

You'll need new fuel lines, tank, plug, fittings, ignition battery, etc. too.

some will argue with me but the rule of thumb I use is 10CC equals .60 2 stroke.......

Check out the RCGF 15cc at www.southeastrcengines.com

Also, Hobby People stock a converted Magnum XLS .52.. If I were getting another airplane that would use a smaller engine in the 46-60 class, I would consider this one..

Look up the DLE 20 in the gas forum down the page.

Converting a glow engine to run on gas isn't practical. The compression is too high for gas, the porting is for high RPM which gas isn't as good for, and you'll have to scratch build an ignition.

RE: Glow to gas
 

So are you saying that the .90-1.20 size glow engines that have been converted are no good?? I'm curious now as I am liking the idea of these smaller gas engines.. perhaps they are modifying the head so that the CR isnt as high.. Icant imagine they would build them if they werent going to work..

or are you simply saying that doing a DIY conversion isnt practical?

I see Paroflyer's made one post, as I read this. No information about his building, flying or engine skills.

Since this is the beginner forum, I suppose we should point him to those long threads in the engine forums about running on part gasoline, part glow fuel, and using a glow plug.

Or, we could go into lengthy discussions about needle bearing crankshafts and the weight a spark ignition system adds to the plane, the expense of that addition, etc, etc, etc.

However, those topics have been well discussed in the RCU engine forum. I'll suggest a search there.

Best wishes,

And Fox now has a .50 CI gas engine. For the lower energy of the fuel I would think the Fox .50 would have more power than the Magnum .52, but both may be reported. The Magnum has a pumper carb and the Fox does not, but has a really good redesigned carb.

the DLE 10 is gonna be awesome

This was the information I was looking for. Thank you.

Thank you for the conversion idea. This is the info I was looking for.

It depends on the the weight of the aircraft. A rule of thumb of 10cc to .60 sounds fine for lets say the U-CAN-DO plane. But for a warbird with ignition battery as OPJOSE has stated you might want to go as high 20cc or 26cc. It really depends on the model. Look at zenoah or fuji.

Also since you are in Kansas the elevation doesnt play much into your decision. But the higher your altitude the more engine you need.

RE: Glow to gas
 

10cc equals .61.

RE: Glow to gas
 

Right Mk23socom, I wasn't saying it can't be done or can't work. I was saying it's not practical as a DIY project, especially for a beginner. The power output will be lower with gas, the weight will be higher, and no matter how well it's done, a conversion is a adaptation of a design to do what it wasn't designed to do. Add to that the expense and time invested, and it's tough to make a case for gas on these smaller engines.

RE: Glow to gas
 

Right, but a .61 2 stroke glow engine is FAR more powerful than a 10cc gasser, and that's the problem.


You'll need to be in the 20cc range for a gasser to get a similiar amount of power relative to a newer .61 glow engine.
