RysiuM: I was more so wondering what happened to winspan99. I miss his deep enthusiasm he had. I bet he could help out here....check out some of the links he had posted. He really is a go getter. Kind miss that guy! Capt,n P.S. The E85 is on my back burner too!

I think he's around.

Hi folks, "contrary to reports of my demise I am still alive". I have had some events that slowed my experiments down, and then cold weather set in here in Colorado, and ordering synthetic oil through the LHS has been unsuccessful, but I am going to try some Fireball Hot glow plugs from foamcut next with E85 and 12% synthetic oil, then try 1 part 15/15 glow and 2 parts E85 plus 7% more oil and report my results. My goal is a replacement fuel for my helicopter, a Raptor 50 with OS 50 engine. That will have to be a very reliable combination. One thing to bear in mind about my experiements is that I am at 6800' MSL ! It's possible that I require carb modifications and fuel mixtures that are not necessary at lower elevations, and vice versa. In the meantime, enjoy this picture of me at the American Idol auditions.

I like this photo too! Man that must be a fun little airplane!!!!!!!!! Capt,n

You know it John, it's a blast to fly. It's just like being inside a large model airplane. Empty weight is 282lbs, top speed is 160mph, cruise 125mph. With a roll rate of about 100deg/sec it rolls well and glides at 13:1. The fuel is 50:1 premix of 87 autogas and mineral oil and engine is a Rotax 447 with 40hp. It burns 2.5gph in cruise yielding about 50mpg on cross-countries. In aviation dollars, that's just about free. There's a video of me flying it on Youtube: [link=http://www.youtube.com/watch?v=k3-3nZ6sXkI]My Private Rollercoaster[/link]

Wow!!!! That Video was neat. I do not think you want to try that airplane on Gas/glow. Speaking of gas/glow or gas fuel with glow plug no ignition...I got to post a photo of a Homelite 25cc I worked on and maybe messed up the squish band area. It viabrated bad on glow for some reason. I never did try the same engine on strait gas to see if it was smoother. I may try that too. Regards Capt,n

Nice vido.

Wingspan99,

Wow...that's a great vid!

Let us know how the gas / glow or E85 / glow mix experiments work out.

Thanks

Glad you all enjoyed the video. I will keep everyone posted on my experiments with the Fireball glow plugs.

2008th post yeah

I have been reading this thread for about two weeks. After the cdi quit on my TT 90 that had been converted to gas. I changed to the OS "F" type plug and gave it a try. On regular gas oil mix. It runs good on top end, but after idealing for a few seconds it starts to 4 cycle and is spitting out a lot of unburned fuel. Had to quit it was getting dark, and then the weather turned cold. When it worms up I plan on leaning out the low side and trying it again. Transition was very rough. Can I mix glow fuel with the gas oil mixture? Anybody got a good CDI for the 1/4 inch plug?

The glow plug is getting cold at idle, so if you add some glow fuel to the gas it will help a lot. There's another long thread on that idea called glow/gas. One fella had good luck with using 10% nitro fuel with 10% oil at 1 parts glow and 2 parts gas giving about 3% nitro in the final mix. I've used 15% nitro at that mix with E85 ethanol fuel with good results in a .40 size engine on glow. On my ASP 1.08 I only had good results on ignition. One thing you can do is just use a glow driver system at idle to heat the plug. What kind of carburetor do you have on that TT 90? It's difficult to get a glow carb to work with gasoline on the low end and transition.

2010 posts and starting our 5th year, great job converts[sm=thumbs_up.gif] We should ask R/C universe to open a new category on their menu "Gas/Glow fuel Conversions" I think we have demostrated that this is a viable and inexpensive alternative to power R/C engines, you guys have contributed a lot and should feel proud of your achievements as I sure do, although I don't participate as much as I wish I could I've allways been tracking this thead in search of new developments and to see how this part of the R/C community is grwing. So I'll have a drink on all of you guys and thanks for your support to this thead and making it possible to reach above 2000 posts.
SALUD to you CONVERTS.

The engine had been converted by BME I think, and has a Walbro (SP?) carburetor on it. Itried to contact Keith Baker but have learned that he has sold out and is no longer in the business

Hi Big Jim!! does your engine have bushings or needle bearings?? if it has bushings on the con rod try a 15% nitro glow fuel mixed with 2 parts high octane gasoline and see how it runs, it should work better than gasoline alone, but if it has needle bearings you don't need all of that oil, mix your 15% ntro glow fuel with one equal amount of methanol ( drops to 7.5% nitro and 9% oil) and then mix one part of this mixture with 2 parts high octane gasoline this should give you a 2.5% nitro and 3% oil Gas/Glow fuel.

That drops the oil content to 6%[X(] The fule you are desctibing will have:
gas 67%
methanol 22%
oil 6%
nitro 5%

This doesn't look right for bushing rod.

I,ve used 6% oil Gas/Glow on my magnun 91 and it runs ok, remember gasoline itself adds lubricicity, whereas methanol is dry, but if he wants to keep it in the safer side he can always add oil to the gasoline/glow fuel mix to make it up towathever percentage he feels like.

I was going to try 1 part 15% glow fuel (with 18% synthetic oil) to 2 parts 35:1 gas oil mix. i doubt that I will need the high octain, but I can experiment with it. It will idle fine with out the battery conected at a fast idle. It was too dark for my tach to work, but as soon as it warms up some I hope to experment more....... Still if anyone has an extra CDI let me know.

Thanks for all the help and information
Jim


IF YOU NEVER CRASH YOUR NOT GOING FAST ENOUGH!!

AeroNut sure wish I was down there this time of year

If your talking about Keith at BME, I purchased an exhaust system from him 3 days ago.
He didn't sound like he was going any where.

DANG YALL, this is geting a splintered as the debuts on TV. Maybe we should try olive oil and naptha, atleast the olive oil is good for your engines heart. Every time I try to mix glow and gas all I get is seperation!!! I have just been running Coleman fuel and Klotz in my gas engines. because pump gas , atleast in our area is a gamble at best. We have seasonal additives in the Atlanta area. The Coleman is stable. I have not tried it with glow fuel to see if it seperates. If glow/gas is not universal, it is not VIABLE!!!

Just can't understand your problem with mixing. There are a good number of people doing this without problems. I have been doing this since the start of this thread, and have NEVER had a mixing problem, and I've used different gasolines and different glow fuel brands. I've had the stuff sit around for months and still be fine.

Hey, with pump gas in this area, a gas/glow mix @ the ratio universally adopted through the forum will begin to seperate soon after mix. if you leave it 24hrs. there is nearly, if not complete seperation. I suppose you could shake it before fueling, but you better fly pretty soon! I am using Cool Power 15% synthetic. Maybe that is my problem, I should go to a castor based fuel.

Most of my Gas/Glow mixes have been with Byrons glow fuel.

The word I here is that he sold out Tuesday. Said he was just burned out, and is now building furniture.
