I notice that most auto engine conversions use a gear box between the
engine and the prop. Why is that? Is it because an auto engine's peak
HP is too high for a prop to swing? Is it because auto engines weren't
designed to be pulled around by their crankshafts and don't have
proper thrust bearings? Both?

Are there any auto/motorcycle conversions that don't require gear
boxes?

The sonex can use a VW conversion attached directly.
