Hey, I run Cool Power 15% synthetic in every thing I have that is glow both 2cy. & 4cy. That does not mean the Homey has to run on 15% I just want to take 1 jug to the field. I have run it on 10% and do not see much difference. At this point I must ask what is the deal with gas/glow? Is it a money saver? Something cool to do? I mean I am not knocking it at all, experimentation is COOL, but why not mix your own methonal fuel? I raced karts in the open class and we mixed our own fuel. When I quit about 3 years ago methanol was about $3.50 a gal. The Homey has needle bearings on the rod, so you could mix the fuel/oil @ 40-50:1. A qt. of Klotz is about $10.00. 40:1 is 3oz/gal., you can get 10 gal. of fuel+ from a qt. Now we are @ $4.50. Nitro is available from kart suppliers, the last I bought boosted many gallons for $9.00. Add the cost of the nitro and I do not see more than $5.00/gal. Hey I realize I may be WAY of base because I do not know the current cost of methanol, but it has to be cheaper than gas/glow.

I'm paying 12 to 15 dollars a gallon for glow fuel.
Gas is $3.15 here right now.

On many applicatiohns Gas/Glow runs better than glow and is cheaper to run and build.

No ignition required, less weight and runs better. It even idles lower than gas.
1/3 - 10/10 glow fuel to 2/3 - gas, do the math.

Cheaper and better is always a good deal.

I haven't checked the local cart shops but I have heard alky. is 5 to $6 a gallon in small quanities.

It's been said many times - the engine takes a almost 2 times less fuel running on gas/glow than on methanol. This is the saving. The power is lower just a bit on gas tho. In my case I just mix 5 volumes of gasoline (3.4 dollars a gallon) with one volume of 15% glow fuel (15 dollars a gallon) - so I pay about $5.40 for gallon of gas/glow fuel (with nitro and oil), but from 8 oz fuel tank I have over 15 minutes of WOT on Poulan 25cc.

About Perry carb it is lighter, but I believe you still need to provide some kind of pump for fuel or preasure the tank. By accident I found that Walbro pump is very effective. I forgot to unplug the vent and after the flight my fuel tank wass ssucked in - never returned to the original shape.

Ralph. I am not trying to start a controversy, but using your figures, you have invested $18.15 in 2 gals. of fuel. If methanol is $6.00 a gal. + 2.00 for Klotz I think the math is $14.00. Plus methanol produces more power than gas! Look at any specs. for a glow motor and you will find that it will turn bigger props than if you convert it to gas. I am equally divided between gas and glow motors. Any given engine will produce more power on methanol than gas. Thats what top fuel dragsters are all about. I just converted a ST-3000 to gas, I expect it to turn a smaller prop. I think you miss my point, I like glow motors, my 25cc Homey is an absolute pleasure to run, starts easily, idles like a kitten, runs like a lion, and has no IGNITION as you refer to it. I like my gas motors, I have several 50cc motors, if you want to get right down to it the deisel guys are probably laughing at all of us!

Hey, a muffler tap is all that is necessary for the Perry, remember if we are going to mix breeds here a weedeater converted to glow, is a glow engine, and established glow proceedures work well.

WOW!, thats better than if it was a gas/ignition engine!

I have 4 engines on gas/glow now. all my engines seem to have more power then they did when they was on just gas. I just converted my 35cc from ei to gas/glow. When it was on ei I was able to get 8400 rpms. on gas/glow I get 8550. That is with a 18x8 prop. I not saying that you are wrong. I am just saying that I am getting more rpms with gas/glow then I am with ei. I have not ran a engine with a mag in a long time to know what I am getting.

I think thats my point. methanol is going to boost a gas( converted to glow) engines performance even if mixed with gas. The larger portion of the fuel is methanol. reverse the mixture and I bet it wont run. What a gas/glow mix I guess is, a move to econimze fuel usage. I understand the concept, but lower power and economy sounds like my Dads 1967 Doge Dart. What is cheap about this hobby? I know your gas/glow mix is cheaper than straight glow, but gas is cheaper than gas/glow. What are we doing here? Listen--I am hanging out here because I think this is about the most interesting place on RCU, bear with me!

With gas/glow you have more power then just gas. not less power. It is cheeper then glow. less weight then gas. (no mag, no ei module, no battery.) Lower idle. Very reliable. No gliches. and a lot cheeper. One of my engines is a homlite 25cc that will tern a 16x8 8000. It is 2 lbs and 11 oz. I have about 25 bucks in it. It is hard to buy a engine for that.

The best part about it is. It is cool. I have a lot of people ask me about it.

the best way to know is to try it. It is fun. It is not for every one but it is a lot of fun

Gas/Glow

1. Less weight. (No ignition system; magneto nor CD, and further, a glow adapter and plug weighs less than a spark plug)

2. Utter simplicity. (No ignition system to wire, maintain, etc.)

3. Less cost. (Glow plug adapter & four stroke glow plug = 18 bucks. CD ignition = 80 bucks.)

4. Less maintenance. (No extra battery to charge, no glow glop to clean off the airplane.)

5. No interference. (Mount your radio and throttle servo right on top of the engine if you are so inclined.)

6. More power than gasoline operation. (Most engines gain 150 to 300 rpms over pure gas operation.)

7. Easier starting.

8. Slower, smoother idle.

9. The ability to use cheap and easy to obtain gasoline engines instead of buying high buck glow engines.

10. It's fun!!

It's the best of both worlds; glow and gasoline.

Hi guys, I still havent had time to try and fire my homie 25 up after purchasing a glow plug adapter from C-H.
I have a question though: Now that I will be using gas/glow, I have the original prop adapter that I bought from Ken Lambert that was to be used with the flywheel. What will I need for a prop adapter after I remove the flywheel? My prop hub adapter ( to be used with the flywheel)will no longer work will it? Anybody got one that will work they want to trade?
Thanks!
John

Why not fire it up with the flywheel in place and a prop. Make sure you are happy and then either cut that flywheel center out with a hole saw and then true it up and us it. or get another flywheel and chop it up.
Matching the taper on the shaft is the big obstacle.

Gas has more BTUs per pound than Alcohol.

You can put more Alcohol in the cylinder that is where the extra power comes in.

Gas is more economical than Alcohol. More fly time on less gas.

av8tor1977 said the rest.

Try it you'll like it.

but we do need to add the 1 bad thing about gas/glow. You need to lock down the prop hub. The engine will run back words and though the prop hub off. It did it to me. and it hurts. what I did was drill a hole in the side of the prop hub and tap it. Put in a set screw. Lock tite works too.

av8tor1977

What do you do to start your engines so they do not run back words. (I do not care if my spelling is wrong) lol

Paul

It's the homonyms that make it hard on a spell checker.

Here are some pics of my weedeater conversion. Captainjohn, see the pic of the regular automotive sparkplug and my glow plug adapter, you will see that i cut it in two places and then ground two flats so i could use a 9/16" wrench, once cut the ceramic will almost fall out, you are left with a 3/8" hole at the top but there is a shoulder at 5/16", i drilled this to .36" and pressed in the 3/8" aluminum rod then tapped it to 1/4-32. Still no muffler or velocity stack on this engine yet and i'm getting 7200 rpm on a 17x6 which looks like it will be good for my 9'-10' B2 bomber spad that i'm getting ready to build.

OK fellas yall convinced mt to try gas/glow in my Homey. Without searching back thru 77 pages, tell me exactly what to do. I have a new jug of Cool Power 15% synthetic. Am I understanding 33% glow, with the balance gas? Regular, premium? Anything methanol/ethanol is not common here. Also what size bucket should I get to catch all the money coming out of the exhaust? lol!

Planepounder, your supposed to use 1 part 10/10 glow fuel and 2 parts premium gasoline, make a glowplug adapter, use a 4 stroke glow plug, richen the needles and away you go, as for the 10/10 fuel, in my first runs i actually used some 20% nitro / 12% oil fuel from a car/truck that i had laying around and it worked fine.

KI8FR my engine only starts backwards about 10% of the time while using a chicken stik, i have a nylok nut on the shaft so i don't have to worry about it coming loose, i'm sure with a starter the chance of starting backwards would be reduced.

I was not talking about the nut on the prop. I was talking about the prop hub. If it is threaded on it will unscrrew.

I do not have a starter that will spin my 35cc. I run a starter on my 25cc and that works great. My 35cc will start backwards about 50% of the time. I can flip it backwards and it will start backwards. it sucks. lol
Paul

I had a hub come off once when The engine kicked back, the flywheel also flew off too! Put a piston stop (if you dont have one fill the cylinder full of small rope through the plug hole) put Loctite in the crank threads, put your prop on the hub and tighten the snot out of it . It will stay on then!

Sorry about that KI8FR, i guess i'm lucky that my weedeater had a long shaft that i had to cut down and then thread so my prop hub is actually only a spacer that bottoms out against the taper from the flywheel.

Try your 12v starter on 24v.

Don't use it for more than about 5 seconds at a time.

A lot more starting tork for a few bucks more.

We hooked up with an alarm company.

They are always changing out 12v 7ah batterys.
We get them for free by the case.

The key to that Locktite holding good also...is to have the parts cleaned ...do not have any oil reidue. Capt,n

Well converts I'm back!!!!! after a long absence (vacation) and eager to start in the hobby again.
I use JB weld or the black CA that has rubber in it it holds the hub perfectly.
GAS/GLOW is a blessing for us gas converts and I feel proud of the achievements that we have accomplished over the years(77 pages is not easy to achieve) and we are still going strong!!! lests keep at it and enjoy our conversions to the MAX.
