I've heard a few times about guys that have cobbled together a starter setup (using a standard starter) such that the plane could be held with both hands and pushed into the starter cone which would run as long as the plane was pushing on it. Once started you simply back the plane off. This way you're never in front of or to the side of the spinning prop. I've thought about it but haven't seen a plan for one. Anyone here seen or developed such a starter?
