Bob Wood has a fixed-gear XL flying - he parked it in my hangar when
visiting northern California a couple of years ago. There are several of us
building that configuration.

And parasitic drag is related to the cube of the airspeed. But
you're right, apples to apples is going to be hard if not
impossible. I specified small fuselage, large wing, 180 hp because
my impression (and it's only an impression) is that there might be
enough of that configuration, fixed gear and retract, to get a
comparison. I haven't ever seen a fixed gear XL, for example.
