that may work but it probably wont turn the engine fast enough, Lite Machines Helicopters (LMH) has one they market for the norvel engine,there is the sullivan cricket,,but try a search for 1/2a starters, lots of folk make their own,have seen them made from rc car motors....try the drill first it may work, I think I saw where someone made on from a socket filled with silicone sealer..it just needs to turn fairly quick....Rog
