I am preparing to build one for the purpose of a Cross Country Event. I am planning on a .91 or 1.20 4 stroke with a 50oz fuel tank. I need the fuel load because one of the legs is over 58 miles. I am figuring that with the economy of a 4 stroke over a 2 stroke I SHOULD be able to make it. A friend of mine has one with a 2 stroke .61 engine and a 28oz fuel tank. We could get about 25 miles to a tankfull at 45MPH. Am I off base here or will I need something different.??


TIA
