The Vw is too heavy I think. Mignet and the french used the 17hp
Aubier et Dunne engine quite successfully. I havent found a weight for
the Aubier but the Scott Squirrel at 16hp weighed 85lb so I'm assuming
the Aubier would be similar. that puts the vw at about a third too
heavy and would lead to the insidious weight spiral.(heavier engine
needing a stronger structure, needing more power and bigger wing etc)
To the best of my recollection, the little litterature that I saw for a
single seat Flea described and showed a Harley-Davidson V-twin engine with a
belt reduction drive. I subsequently saw some passing mention of 2 seat
varients with fully enclosed cabins and up to 125 horsepower aircraft
engines.
