Didn't we do small gas engines already?

Too bad we can't look up threads about all the advantages of the new "glow plug" engines, by 1970 there won't be any gas engines left on the market!

Why did we switch from gas to glow anyway?

Saito is a large company that took the time to modify there engines and develop there own small pump carb. They have a .82 and a1.25 allredy an the market. They sell on average $150 then there glow versions but the caust is quickly negated by the difference in fuel price. I have the 125 gas engine and i love it. I am however hoping O.S. who just put out a Gasoline 55cc will continue to put out smaller 2 stroke gasers. Glow fuel is rough on the airframe and even rougher on the wallet.

You said it!

Hey lets make a fuel for our planes that,

1 Spits out alcohol that will eat though just about every paint on the market
2 Spits out a think oil that will creep into every nook and soak into wood ruining it.
3 Turns into acid inside the engines crack case.
4 Cost $30 a gallon
5 The engine uses 4 times as much of that $30 a gallon fuel.


It's evil but I still love it!

I switched over to gas engines for the following reasons:
Price of glow fuel. I fly 120 size and up planes .
Gas engines run more reliable than glow especially inverted installations.
Once set-up properly it's flip and go!
Added bonus, clean-up is a breeze!

As for electric motors I agree with others about haveing engine noise. For me electrics
make planes sound like gliders. We have small to large electrics in our club and they all
have one thing in common, there quite! We kidd each other about the noise and
lack of noise. To each his own.

It seems the present market is split between gas and electric with some glow
hold outs (40-60) size engines. One thing for sure we still have choices and that's
what makes this hobby fun.

So the small walbro carbs for the FG14 and FG20 are made in the Saito factory ?... don't make me laugh..

That's why I went Diesel!
....then right back to glow.

50% more power!.............Yeah but you can only use that power on big slow props.
Same easy starting!..........LOL, yes you will be in the pits F'n with the engine all morning like the glows but now you have to deal with piston compression too!
Scale sound!....................If you call a two stroke running at 8,000 rpm scale sound.
Runs twice as long!...........Yes you'll be flying a slow dog around the sky twice as long, as glow guys pass you at twice the speed but for only for half as long.
No more glow plus!...........Say hello to my little friend Mr. Piston Compression Knob! You'll be shaking hands with him a lot!
Less engine where!............Yes your engine will be well oiled with thick black smelly oil.


Oh we forgot to mention

Model Diesel fuel cost $32.95 a gallon!
Sprays castor oil all over your plane like glow but now it's BLACK and permanently stains everything!
Smells like industrial waste!
You can only open your carb 2/3 max any more and the engine will sputter until you land and clear it out!
Eats away even gas proof fuel tank plugs!
You thought fuel proof paint was hard to find? Now try Ether proof!
Having to use opaque fuel lines no more looking for bubbles!
Lean and rich carb setting sounds are reversed! lean sounds like the engine is drowning in fuel wile rich screams and over heats your engine.

When they invent a gasoline two stroke engine that doesn't sound like it's about to come apart at idle is when I'll switch. They all do it, annoying popping and snorting sounds you don't get with glow. Not only that, but they don't fit in my size of aircraft, but even if they did I'd stick with glow.


Also, I'm not sure how you guys are treating your glow engines but mine are quite reliable.

Not cheap but very interesting

I have a few airframes that would be happy to meet Mrs. 9CC Gas engine

Any idea who, if any one is selling these in the USA?

I own a LHS and this is what I see. Planes in the 30 size and down are going electric. Planes in the 120 and up going gas. That just leaves the 40 to 60 size glow. This does not mean that they can't be electric but the cost of battery's goes way up and so does the number of battery's to fly all day.
The five and six cell battery's will have to come way down to make inroads on the mid size planes.
Electric still require multiple chargers and battery's to keep them flying all day. Dennis

Electric in .40 size to .60 size is still massively expensive and the cheaper battery packs just don't deliver the lifespan (despite what the pattern guys tell you).
I've stopped buying .40 to .60 size engines. I have a few but I'm flying the cr*p out of them to get some bang for the bucks I put into them.
Thereafter its just 17cc gassers and up to aroun 30cc size planes. Bigger is just too much of a hassle to move around and they don;t deliver more fun.

I think there is an opportunity for a 9cc gasser for the 4 size planes, especially if they can reduce the size of the ignition unit

thats the problem with gas when you get too small. the ingnition can't get smaller. Just ask TOM. I believe given time the only planes that will use glow will be the 40 to 60. My glow fuel sales is down over 50% from what is was 4 years ago. Dennis

captinjohn

If a person wants to run glow fuel...you can do it a lot less expensive if you buy strait alky and mix it yourself. Use klotz oil and no nito like they do in europe. High compression engines is the key....like Moki, Supertigers...ect. It can be done. The use of a good 4 cycle glow plug like a OS Max "F" plug is needed also. I like the DLE small gassers now. Its flip & fly. Cost is next to nothing for fuel. Goodbye glow for me....except for my ABC .51 Como Supertiger! Capt,n Oh I got electric...gets boring after a short time!

Perhaps I see things a tad different than most. I truly believe that Gas is here to stay and with the advent of the smaller gasoline engines coming to market I can see glow being scaled down.

I personally would like to see DA, OS or for that matter DLE make a 15cc gas engine.

I do think that the 20cc engines are becoming drop in's for the 90 size planes. I also believe that a 15cc would be a great match for a 60 size airplane.

I am currently installing a Zenoah G20ei on a great planes big stick 60. I will also say this. If I had a dedicated 15cc aero derivitave engine that was gasoline and not glow converted I would have used it.

My opinion fwiw.

When glo came on the scene many years ago, the switch from gas to glo was a quick one. There were several reasons for the switch but the main one was probably the simpler setup and operation that glo offered over gas. Even back then, not all modelers had the skills or knowledge to get a gasser running. You had to assemble your spark ignition from components and get it all right .... then you had to worry about the points and timer mechanism. If the points got dirty = no spark. Some guys could never get the hang of retarding for starting then advance for run .... along with getting the carb mixture set correctly. Just look at all the seemingly silly questions from newbie gasser users on this forum and you get the picture. It really wasn't much different back in the day. Some guys got it with gas engines and were successful, some just didn't get it at all and moved on to other hobbies .... or to glo power.

About the same time, engines were improving in quality and performance and all the new engines were glo so there really wasn't much of a choice. By the early 50's or so, it was pretty much glo or nothing and many of the old gassers were retired to drawers or cigar boxes where guys like me found them a few years later and were marveled by them. Of course as young teen agers or younger, we had no idea how to make them run and the ignition parts were long since lost. End of memory lane ......

Simply stated ... the old gas engines died because something better came along and replaced them! That may reverse itself again if the mfgrs. can reduce the size of ignitions, carbs and of course those big ugly spark plugs. The technology is there for smaller ignition units but I'm not sure modelers are ready to pay the price for them. Carbs will be another issue all together.

The time will tell if the Saito, Magnum, FOX and NGH 9cc engines will get success.

FWIW, we flew old time gassers with spark ignitions on our RC free flights...My McCoy redhead 60 got me a trophy about 40 years ago...Pro Line radio on AM 72...Gee, I wonder how we did it..??
No shield on the spark plug wire, just a 10 K resistor in the lead at the plug...
AFAIK the old timers are still winning contests with serups like that...
The Proline was a REAL radio.... Mine still works just fine...

Ever wonder which came first gas or glow? History will show you gas did. Went to glow for more power. Glow fuel costs more now so your going back to gas. Electrics have there place but will not replace gas IMO.

So when they come out with a $12 10 oz. motor that produces 20 HP and runs for 60 hours on it's $5 46volt 2 oz fuel cell, your going to stick with a gasoline two stroke engine?

HI this applies to glo engine use only
YOU COULD use SIG clear dope on film seams ( monocoat and ultracoat )and decals-to keep them on for the long hall- you will not see it when it drys i will use the clear dope under the film ,on the balsa wood, with no issues were i know glo fuel will be present and might seep into the balsa for ex. at the ailerons near the fuse and the elevator on the engines exhaust side-i only know this from working with silk and dope finishes from 26 years ago do remember film is still the lightest covering process you can use-paint adds a good deal of weight to an airframe PERFORMANCE = POWER TO WEIGHT RATIO always !
glo soaked balsa can be repaired with a dry cleaning product call R2x ( i thinkor close to that powder in a spray can )and then coat the balsa with clear dope to get the wood HARD and protected again (balsa gets very soft from glo fuelthat is why we fuel proof )
old timer -building and flying a lot for 26 years do keep glo fuel off the balsa of your airframes for them to stay structurally sound for many many years
rock on !! BEST REGARDS TONY

So I am wondering, what is it that will keep an ignition from getting smaller? Just because the current offerings are the size they are does not mean they will remain this size. I am going to guess that they will come down in size significantly. Possibly even mounted to the engine itself. Also on the smaller gassers we will be able to use one battery to power the whole plane.
It is more a matter of motivation. That is what drives innovation. I look forward to some great products heading our way. If companies like OS are going to stay in business, I think they have to invest in small gassers.
I have a very large collection of glow engines and I personally love flow. It has gotten to where I hate having to buy glow fuel though. I could not imagine if I did not have a local hobby store. What do you guys do?
I am finding it inevitable that glow is quickly becoming a novelty. While electric is not for everybody, the battery prices do continue to come down.
