    Got any data on that?Â*The math totally doesn't work on that.
    No, sorry, I make this stuff up as I go along...

    Looking at the link, I love how you guys over there can just go in and order that level of mind-numbing stupidity off the shelf ..... almost makes me thing of emigrating! (we have performance shops and aftermarket nut jobs for sure, but I don't think we are at the "wheel in your lambo and get bolt on 1500hp" stage)

    PS - to answer SpinnerRow's previous question, no, this post has nothing what so ever to do with RC and or DLE20's .....

    Now, better start saving for that lambo and flights/shipping I think .....

    I would be that mind numbingly stupid if I had the money! Riding in one of those is almost as cool as the realization that your wanker is used for something other than peeing!

    OK these last posts have been the best laugh I have had all week!

    And no they had nothing whatsoever to do with the DLE20.

    maybe we get back to the topic, but lambo 1500 hp ????????? 15 years ago when i ran Top Alcohol i had 1800 horses on Keith Black 548 cid Hemi stage 3 with newberry combination supercharged on straight Alcohol with 30 lbs of bosst ?? must be miniature Horses in the Lambo since Italians are short folks too i guess.
    DLE 20, dont worry about Ethanol in the gasoline mix it fly it, works just fine, no matter what pump you used.

    The problem with the ethanol is it eats the silicone gaskets it the carb and the motor. It will make a walbro carb diaphram hard over time. Run all fuel out after you fly and there wont be any problems.

    RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

    Tmaucher is right about ethanol in gasoline. Ethanol causes delamination of rubber, plastics, synthetic hoses, etc. It is also a strong solvent and as it breaks down varous organic materials they go in to solution. Some of these dissolved materials tend to settle out and form various gummy materials. So, in any fuel tank, engine system like in a DLE 20cc engine in a model plane, fuel containing ethanol will attack the rubber, plastic and synthetic components over time. Because ethanol is very hygroscopic, (holds water), it is also thought to form acetic acid as a reaction product, which causes metal corrosion. I worked on these problems, as a chemist, when they first went to an E85 type fuel in a big way in Brazil and experienced huge problems.

    Despite my comments, I would not worry too much about our 10-15% ethanol containing gas. I would recommend that you inspect your carburetor rubber/synthetic components and hoses closely at least once a year.

    I had the very same questions about blended gasoline in my DLE 20 when I got into the world of gas engines this year. In case you want to try "clean gas", here is a link to search your state. In Colorado, there are only a few stations that still sell it at a regular gas station.

    http://pure-gas.org/

    I've been flying my DLE 20 on straight gas for about 8 months and have not has any issues with it. Great little engine.

    RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

    A slightly related question - I've had plenty of crashes with my Nitro planes, and a few with my gassers. But I've never had a fire break out, even when the tank has been puntured. I'm guessing that's cause there were no real sparks nearby to ingnite the fumes (since the engine was stalled by then). Or could it be that Nitro is not as flammable as gas fumes? I've seen some nice crash-fires on Youtube, but those always involve jets, which, I guess, crash with much more force \ explosive power. Any thoughts? (btw - not that I'm LOOKING for fires, either. I'm past that stage...)

    Methanol does not have the same flammability as gasoline

    Try this...pour a small amount of glow fuel on cement or hard packed dirt. Then with a long stick with a burning match...ignite the Glow fuel. It should ignite soft...compared too gas. Be carefull, where and how you do this. In bright daylite...acohol is hard to see burning! Capt,n

    Jet go boom because the engine is spitting fire out the back end, unlike a gas/glow engine that goes boom internally. Open Flame, Gas Fumes, BOOM!

    Thanks for the great link to "clean gas" stations. There are a few listed that are not too far from me. Given a choice, I will use regular gas without any methonal added in my DLE 20cc.

    RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

    Glad to help! Yeah, I bought 5 gallons of the clean gas to stock up. And then I used 3 gallons of it for my other lawn powered engines because the DLE doesn't use all that much.

    There are some guys in my club that buy the blended gas and then add water to it to remove the ethanol. It actually works, but it can be messy! I’ve never done it myself, other than a 3 oz test in a mason jar, so Google it for complete instructions if you want to try it.

    Very small distinction for several posts in this thread
    M
    ethanol (CH3OH) is the primary component of glow fuel.
    E
    thanol (C2H5OH) is added to gasoline.

    Thanks for the correction on the fuels. I meant to say Ethanol when referring to gasoline and instead wrote Methanol. I'm either too new to gas r/c engines or it's an age thing!

    RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

    Hello everyone, and thanks for all the great info.

    I'm definately a newbi with gas. Please pardon the question below if it's been covered already.

    A club member suggested using white gas Coleman fuel instead of gasoline from the pump. I tried it just for the heck of it and my elderly Zenoah 26 seems to like it just fine. Yes, it's expensive (but less than glow fuel), but my friend says it burns cleaner with less carbon build-up, etc. and offers a higher octane level (more power).

    I know just enough to be dangerous. Any thoughts, pro and/or con on running this fuel with my shiny new (and as yet unpackaged) DLE 20?

    Some helicopter pilots swear by it. A guy at my club adds 10% white gas to his pump gas.

    I haven't seen the need and pump gas works just fine.

    The alcohol is not a problem. Been using it for years no problem with newer equipment. here is a link to some expert information, Pat aka T.O.M knows what he talks about he's bben working with UAV engines for years. http://www.rcuniverse.com/forum/fb.asp?m=10166972
    You just have to get past his gruff exterior Unfortunately he's not on here any more because some just could not handle his blunt truth ( read his sig line) I have the DLE 20 and just use reg gas and a good 2c oil mixed at 32:1 and don't follow the Tower Hobby instructions.
