Kostas1,

It's really not as bad as it sounds. Once you make the transition to gas, you'll never go back. Think of it this way. $2.50 for a gallon plus another 5 bucks fir a quart of oil which typically last 5 or more gallons depending on the mixture being used versus $10 or more for glow fuel, little to no clean, no need to carry a flight box, just fuel, TX and whatever tools you need to assemble the plane, and this Cap only requires a screw drive to install the wing, or if you are like me I replace those wing bolts with hex head nylon wing bolts. Oh yes, now you are going from using 1 or more ounces of fuel per minute on glow engines to less than one ounce per minute on a strong 50cc gas engine so you can even change the tank out to a much smaller one.

Yes, you will need to replace the stopper, not the whole tank, you will convert to Tygon fuel line at close to the exact same cost as glow fuel line and for EI ignition you will need an extra batt and switch. If you stay with NIcd or NiMH you can stay with your current charger.

If you fly like I do, you'll break even in less than a year. I think I broke even in something like 4 months. 2 years ago I spent over $700 on glow fuel for 4 planes, yes I said $700, the year after I spent like $200 on gas and that was for all 4 planes after converting them.

I have a friend that I fly with quite often that once said to me while he was standing behind one of my gas planes (he never saw or heard one to that point in person):

"that thing smells like yard work" and you know after thinking about it for like 2 seconds he was right because you are essentially running the same mix as you would in a weed eater, chainsaw, etc and in some cases you are actually using a converted weed eater/chainsaw engine.

Later that day I left him fly it and when he landed I asked him if it still smelled like yard work now because he was just amazed at how smooth the power was and was grinning like we all do when we flying something we are having a blast with, he proceeded to flip me the finger and converted 3 of his planes within a month.
