Hi gang! A couple of other tid bits I wanted to share with you, one is you will read many times where someone is listing a "Gas Powered Model" or engine. WRONG! They are NOT GAS POWERED, and should never be run with gasoline. This will ruin your engines. They are powered by GLOW FUEL. GLOW FUEL is a mixture of Alchohol,Nitromethane and castrol oil. Do NOT try to mix your own at home, it is highly dangerous and messy, it is easier just to order some off the computer or go to your nearest hobby shop. Tower Hobbies is one of the largest Hobby shops and sells glow fuel all the time. Again do not use gasoline in your model it has no lubricant in it and will burn up your little engine in less than 10 seconds. Also,one other note. It takes a battery to start your engine off  its Glow-head. The battery size is 1 and a half volts. Period. Do NOT use a car battery, or a lantern battery, as these are 12 volts and 6 volts respectively. You can buy a larger battery with the same 1 and a half voltage at your local hobby shop or get an "igniter" stick there too. It has a rechargeable battery inside it along with a charger to re-charge that plugs into the wall. As always, play it safe, Read the directions that come with your model, and let your Mom,Dad or older Brother know where you are at and what you are doing. See ya gang! Have a Blast, Mikey Daniels
