5 knots at cruise is about the same as I can report without wheel fairings (mine
is a taildragger with similar 500x5 wheels). And is also about what RV pilots
have noted (6" wheels).
However, both on mine and the RVs, it is the leg fairings that make the biggest
difference (about 10 knots).
Similarly, a tailwheel fairing is reported on RVs to be worth about 2 to 3
knots,
which is what I've recorded (at Vne) on the TD. Haven't tried a tailwheel leg
fairing (yet).

Subj: Re: Europa-List: Re: Tri-gear speed kit
I had occasion to fly my Tri-gear, 912S, without the wheel spats during last
winter
because of the soggy conditions and mud.
Knocked around 5Kts off the cruise so I surmise that each of the parts over the
flap hinges etc contribute a little to overall speed gain. Not weighed the spats
though so might do that next time I have them removed.
