Interesting instructions for installing the McDowell starter are here at a T-Craft forum: McDowell Starter - The Taylorcraft Discussion Forums (Post #19)Yes, if you have it in an airframe that doesn't take a lot of HP to fly and can take the weight of an electrical system since you need a starter to start a redrive engine.
Wish someone would design, manufacture, and sell a Mc Dowell hand starter for the VW.
I had imagined it used some sort of recoil handle like a lawnmower rope, but it was a lever on the floorboards that you pump a few times that uses a cable/ratchet/pawl mechanism to compress a spring in a housing around the crank/prop hub. The spring does the cranking. Pretty neat. Installation was more involved than I would have thought (cutting the cowl, etc).
