small gas engines
i have flown nitro for many years. i like them and wouldn't waste my money on a small gas engine. the savings ain't enough unless you run a 50cc gas engine or larger. with a big plane you need one. with a 40-90 size you don't. they arn't reliable enough for me. every thread i have read there a problem with the engines. the norvel ain't profected and neither is the ngh 9 cc. why spend 200.00 on a small gasser when a 46 nitro only cost half and they run very good. os engines,magnum, thunder tiger, enya and asp. i read all this trial and error people are doing pulling there hair out trying to get these gas engines running right.why doesn't the factory that makes them ......do this and sell you an engine that runs reliable. i can't see it. but thats my .2 cents on the matter and i can buy alot of glow fuel for 200.00.

Nice thing about this hobby, you get to do what you like. I have no more glow engines that I use and like the much cleaner planes as well as only a few bucks spent to fly all week. To each his own and as long as you are happy so be it!

They tell new guys to ask me a lot at the field and I have a current standard answer.
for engine sizes:
0 to .40 cu electric
.40 cu to 1 cu glow
1 cu and up gas
This is always going to change and there are exceptions to any rules.

I tend to agree and don't generally even participate in the threads about small gasoline engines. For me, the break point is 20cc. 20cc and above, gas is the way to go. Below that, stick with glow. If the cost of glow fuel is getting to you, then mix your own fuel. Go to a automotive speed shop or race track, or a go kart racing outlet, and buy pure methanol. Mix it with the proper percentage of oil and go for it. If the engine was designed for use with nitro, then you might get better results with this home brew fuel if you raise the compression a bit, and/or use a hotter glow plug.

I like small gas engines because that were all that were available when I was a kid. I wish i could get a hold of a Brown Jr or a Phantom P30.
Then i would show you young fts a thing or two

I have a Super Champion 60 with a McCoy Redhead head on it. It was converted to glow before I got it. Flew it CL. Likely you could get or make the points and buy the coil and capacitor for it. It still has the cam for the points on the crank. Make me an offer.

I had an Atwood Super Champion .A good engine but if yours has been hacked up and run on glow i dont think I want it.
I tend to get rid of my engines once I am thru with them. Too bad, I had some good ones. How about a Morton M5? I sold mine for $13.

i never said i didn't like gas engines......i do like them however i can't see why the factory doesn't make them to run better. i see threads where people are changing mufflers on them, drilling holes in the muffs, adding bigger pressure taps, changing carbs, changing carb parts even trying nitro carbs on them. just make them so they run good and i would buy one it's just all these threads are confusing sometimes. maybe i should stop reading them .......huh.

The small gas engines are a huge boon to those modellers who cannot get glow fuel in their locales. Even here in the USA there are areas where glow fuel is difficult to get and very expensive. There are countries and islands for that matter where glow fuel is just about impossible to get. Thus you cannot effectively use a glow engine in those conditions. So gasoline or petrol is the only way to go. Now granted you might be able to use model diesel fuel with a model diesel engine, but even it has become tightly regulated due to the ether used in it. So it may or may not be a possibility either.
But yes some of the small gas engine brands are not really for newbies or beginners. But other brands are better though. The small engines tend to be more tricky to get to work right.

gizmo......read the threads on the norvel and ngh 9 cc gas engines. you will see that i'm not confused at all. sure there are gas engines that run decent but the only one that is about 90% is the evolution 10 and 15 cc. nice gas engines.

Nerver read them as I really have no interest in those little engines at this time, not to say there is anything wrong with them or the concept. The larger engines (of good quality) run well unless someone fiddles with them..........for the most part. From what I have seen the smaller gas engines are about the same as the glow engines of the same size with a little more weight for ignition and batterys in many cases.
I think these little engines need a little more time for improvement from what I have seen at our field?

How an engine runs depends a lot on the operator. The manufacturer can only supply the engine. The rest is up to you
