Hi Pete,
My aircraft which I built was a Classic Mono for about 650 hours and had a 912UL
80hp with Airmaster and 62" diameter tapered blades. After converting it to
a tricycle and installing a 912ULS 100hp with 64" diameter wider blades, it has
flown about another 400 hours during which time the firewall forward was altered
to the Neville Eyre cowls, making it very much more like the XS f/w forward.
(See attached image.)
I never actually measured the propeller ground clearance with the fuselage
horizontal
while it was still a Mono with 62" propeller, but subjectively I guess
it would be much the same clearance as an XS tricycle with 64" propeller.
While it was still a Classic Mono, Airmaster made spinner bulkheads for me which
very well matched the Classic cowls. No doubt they still have the molds. When
I converted to Nev Eyre's cowls, I acquired a smaller diameter spinner which
matches the XS cowls and gave away my big spinner with bulkheads to someone who
needed them.
I don't believe that it would be necessary to lower the XS tail wheel spring,
because
reduced propeller ground clearance with a 64" propeller becomes more significant
when the tail gets raised during take off. Yet I flew happily enough
like that for many hours before concerting to tricycle u/c.
