A little further info from my database: I already noted that the average
"claimed" 75% performance was 93.5% of mfg's stated top speed in my
database. Interestingly, the average numbers for the entire RV series (32
models from RV-3 to RV-10 inclusive, if you count all the engine sizes
identified for each model) is 95.3%! I'm not knocking Van's (I have an
RV-4), I just wonder how they do it? If the math is insurmountable, the
Cd's must be very low... Mine is not as fast as it's supposed to be, but I
have the old style wheel pants, no lower strut fairings, and poor fitting
upper strut fairings. I know those are critical---I plan to clean them all
up this summer. I once had just one upper fairing on the right side come
loose and slide down the strut about 10 inches (held by a spring). Cost me
20 mph in cruise speed!
I'm not *even* going to talk about antennas!!
