Home made fuel for Moki 210

[Dan Reed]

I have a Moki 210 that is eating me out of house and home.
I'm planning on making my own fuel using Klotz for oil.
My question is can I use denatured alcohol? Or do I need to use methanol

[tcruiser16]

Why not convert to diesel?

methanol

Denatured alcohol is ethanol that has had various ingrediants added to it so that is is poisions so that you don't have to pay liquor tax on it. Some manufacturers actually use methanol as an additive. The problem is you don't necessicarily know what else has been added to it and what the effects running would be. I would be worried about consistancy and moisture content also. A product made to be used as a stripper or for a backpack stove may not have the level of distallation and or quality control that methanol manufactured for use as internal combustion fuel. I would stick with good quality methanol. You may check with FHS supply, I think they sell methanol by the gallon.

I have been mixing my own fuel for my Moki's for many years. I can get methanol at a local boat drag racing garage. And I mail-order the oil from Morgan (maker's of Cool Power). I like to use 5% nitro in the big mokis, so I either buy that or sometimes I just mix some 15% cool-power fuel with my home-brew. I tend to always have some 15% fuel around for the smaller glow engines.

There is a guy in our club who runs his Moki's on his own blend, which is a gallon of methanol, one and a quarter ounces of Amsoil 100:1, and three ounces of castor.

I do not recommend doing that.

tcruiser16 - Diesel?? Your joking, right?

Dan Reed - Stay with methanol, and Klotz is a good choice for oil.

Moki 2.10 - Great Engine! Had one a few years ago when I started IMAC, but went to bigger gas engines, and gave it to my brother.

I found my 2.10 ran fine with an inexpensive methanol/oil mix, such as FAI fuel; no nitro. It will run great without nitro, and nitro is what makes the usual methanol fuels so expensive. Athough, surprisingly it may not be easy to find. I see Tower hobbies has Cool Power FAI at $54 for 4 gallons (plus shipping)(17% oil). Taht's about $13.50 per gallon + shipping. Possibly that is why you want to mix your own. I used to get FAI fuel at my local hobby shop for $8 to $9 per gallon.

Most of the time I would run mine with methanol/oil with 5% nitro; sometimes with 10% nitro in a pinch. It really did not like too much nitro, and would get sensitive on the needle setting, without any noticeable gain in RPM or power. You can run on 15% to 18% oil. I heard many other flyers a few years ago would run it on 15% oil and 0% nitro that they mixed themselves, but I never did that. All the more power to you if you can mix your own.

Most problems I saw people having with it was getting it started and getting the needle set correctly once it was running. I stayed with little or no nitro. Plug the intake and turn the prop through 7 or 8 rotations to get it real wet. I liked to see fuel drip out of the intake when I pulled the plug. The cool thing about that engine is that you can connect the battery to the glow plug, grab the spinner, twist the prop forward up against compression, and then spin it backwards. Yes, backwards. It should start on the first try, or within 2 to 4 tries, depending on how wet it is with fuel. It is possibe to get too much fuel in it, but I have only experienced that when the engine is hot.

Sorry I got a little off topic here. Did I say the Moki 2.10 is a great engine? Well, it is! Good luck.

I didnt really look into it to much other than seeing an ad about changing glow to diesel in a FlyRC mag. But yes, you can change glow to diesel, depending on model I dont know. They dont do Moki it looks like. I may have it all wrong but glow works on the same principle as a diesel engine.
