The trick is to find the plane to fit the engine. I wrap a nylon pull cord BEHIND the spinner and use it for starting. Works like a charm. I carry a gallon of fuel an extra prop or two and a field charger to go fly. No more boxes full of life support for a glow engine and no more $15.00 a gallon fuel. Gas is the only way to go. I have a friend that converts the engines and does a great job if anybody wants a few of them.
