all you need to do is find some fuel that is 10/10 glow fuel. that is 10% oil and 10% nitro. that is the hard part. I get mine from the hobby shop. it is fuel for cars. works grate..

now take it and mix it with gas 2:1 1 part glow and 2 parts gas. that is hi grade gas. Just mix what you need if you do like a gl the fuel will go bad in about 3 munths.

Set the carb rich and go for it. works grate. I love my gas/glow.

I will look to see what my fuel is that I run in mine. I for got the nameI will put it on here..

Paul

Thanks paul will give it a try

The 10% oil and 10% nitro glow fuel you use is often called Fuel for Large Super Tiger Engines. It is sometimes difficult to find in hobby shops, but it is made by all the major fuel manufacturers. I use Byrons myself.

You don't add any extra oil, and you don't use glow fuel with a higher oil content than stated above. Using this fuel at a ratio of 1 part of the glow fuel to two parts of high test gasoline gives you approximately a 32:1 oil ratio, which is fine.

AV8TOR: Lots of good data in this thread.....gotta keep it going! Capt,n

Does anyone know how to download a thread to their hard drive?

You can start by high-lighting each page and email it to your email address!!!

BUT alchhol takes less air to burn per pound which means you can stuff more fuel in and get way more power than gas could ever put out
same as nitro methane in dragsters has less BTU's than alcohol or gasoline but only takes around 6 pounds of air to burn one pound of nitro methane
where as gasoline takes almost fifteen pounds of air

Thanks Capn,

Looks like I'm going to be busy for a week or so. [X(]

Baxy ... you are correct. Plus the cooling effect alcohol has on the mixture helps, and one can design an engine for use with alcohol at a higher compression ratio. Both of these factors also help the power output of an alcohol engine.

1705493-AndyW -- Try this, I just did it and it worked fine.

At the top of your screen, click on "Edit" then "Select All", then click on "Edit" again, and then click "Copy". Then hit "Start", "Programs", "Accessories", then "Notepad". (I tried it with "Wordpad" and for some reason it wouldn't work)

In the "Notepad" that opens, click at the beginning of the document, then right click, and select "Paste". All the writing that you had copied will be on the document. You can then save it with an appropriate name such as "Gas/Glow Page One" for example.

AV8TOR

Thanks AV8TOR,

I'll give it a try. [8D]

Andy: Let us know how that works. Capt,n

I've got windows XP and here's how it works for me.

On each page, right click. On the dialogue box that shows up, left click "select all". You'll see that all the text is highlighted. Then, right click again and on the next box, left click "copy".

From there, you need to minimize your page and get to your desk top. Find a blank space there and right click to get another dialogue box. Bring the pointer over "New" and a new box appears allowing you to select an icon that will appear on your desk top.

I needed to select "New Text Document" Left click on that and instantly, you'll get an icon indicating a "New Text Document". A quick, double left click on that and that will maximize that feature. In there, in the blank area, right click and then, in the box, left click on "Paste". That should give you the entire text of that page in this thread.

This gives you every single bit of text on the page though and you have to squint to read just the useful posts. Next step is to try to figure out how to select in one click, just the postings. It'll still be a lot of work to save each page, one by one. I wonder if RCU might not have a function to do this that would be just several steps for the entire thread. From there, one just needs to come back here, from time to time, to add any new postings.

Im going to have on bord glow power on my plane and remember Av8tor talking about he has full time power to his glow plug.How about a switch running to throttle where it is on when the throttle is low, and making the throttle horn like a cam where it will open and close the switch? to much what do you think? Im almost done with my 1/4 sig cub and going to finish up on some little things. If anyone can post some pics for me Ill send them to you,Thanks

Larry,

That's a good idea and is done on glow engines, mostly for twins and multi engine aircraft to prevent one engine out.

Yes, you can do it that way. They also make onboard glow drivers that run around $50.00 or less that can be programmed to come on at whatever throttle setting you like. If the cost doesn't bother you, that saves working out a mechanical switch arrangement.

You might also try your engine at first without on board glow power. Out of five airplanes I'm running on Gas/Glow, I only needed to put onboard glow power on one, and that was because I'm running a much too large carb on that particular application and the onboard glow allowed me to run a richer than normal low end to get a good transition.

AV8TOR

In my Poulaan running gas fuel and glow plug I use glow power all the time. I mean I have "ignition switch" on the side of the airplane that turns on the glow plug. I did not bother to use complicated electronics .

Remember I'm running gasoline with only 10% methanol in there so I need glow running all the time (without glow plug powered even at full throttle the engine slows down by 500 rpm). For the glow battery I use two Elite 3600 parallel (total 7200mAh) from [link=http://www.cheapbatterypacks.com/?sid=920616&pgid=loosecells&chem=NIMH]CheapBatteryPacks.com [/link]. It is enough capacity to run for two hours and it is still lighter than spark ignition setup. I have so far over 10 flights and the glow plug is holding OK.

It is cool to just flip the switch and flip the prop without messing up with glow starter - like bick-bucks guys. Every flight my Poulan is getting more power (it is much easier to o a loop on my PiperSpad) and it idles down to the point where the prop starts to turning back. The engine doesn't miss a bit.

RysiuM: I am with you on that on board glow. It is very good insurance that the engine will not quit runnning when you least expect it. Saving that crash....that sometimes breaks your favorite aircraft into many pieces! Capt,n

Hi Andy, I am running win XP also. I was reading page 75 of this Forum and wanted to print one of the posts. I right clicked the post # and it opened another box. I clicked to print the target and it printed all the posts on that page. I got the post I wanted + a few others

George.

You can also just hi-lite the exact part you want and e-mail it to your own e-mail....then print it out there. Capt,n

Thanks guys for the advice,if I went to full time power on the glow would a 1600 mAH Battery be enough ?

If it's full time glow, a 1600 mah battery would be a bit small. That would work fine for part time glow.

For full time it would be better to have around a 3500 mah battery, or a pack made up that totaled 3500 or so. Try www.cheapbatterypacks.com . Another way would be to make up a pack of two 2500 mah AA cells that are available at Walmart for digital cameras. You want to wire them in parallel; positive to positive and negative to negative. If you wire them in series you'll blow your glow plug.

AV8TOR

Av8tor Thanks for all the help! Im shure im going with full time glow less things to go bad.also Thanks for the info on wireing I might have messed that up.I took some batterys out of a electric start homie weed eater for now just to test everything.they are the 1600 mah.I was talking about.thought about building another boat with that engine .My homie on my plane runs good did mods and all that.Im thinking of putting the electric start on another boat or the kids electric scooter and full mod and gas/glow
Larry

I'm not sure if these batteries can provide enough current for the glow plug. Cold glow plug can take up to 3.3A that would be 1.7A per cell. Even so called "High discharge" camera batteries are not rated for that current. The outcome will be much lower capacity than stated on the case. Use rather high dichcarge NiMh batteries designed for such current - the kind made for powering electric toys, rather than cameras, MP# players or other consumer electronics. Most of consumers batteries (even so called "high discharge") are rated for 0.5C.- 1 A is a lot for digital camera, but not much for the model's glow plug.

Thanks for the info,Just so I could fine tune a few things a hooked 2 of the 1600 together and ran the wiring and put a switch on it.Had a little fun in the yard.I hadnt started it for awile.and the diophram is still working great! the walbro carb is off a 36cc poulan chainsaw. works well with or without glow on.I am going to get another batt dont want to build up the weight.A little here and there adds up.I do have another batt pack im going to test on another glow plug they dont say what mah they are but came out of a rc toy my boy had they say trinity nitro,Metal hydride on the pack and shorter then AA but wider There is five in it.Ill test them and see what I can come up with for a batt pack.I used to have them in a homade feul pump for my planes they would last a long time.I used a electric motor out of a tire pump that pluged in a cigeret lighter and a hand pump that broke it worked great. I like to make stuff.I havent charged them in abt a year and they had charge left in them.But anyway Ill see.
