- speed kit built by Bud Yerly. I went from 119 kts to 137 knots (at 1000 ft
full throttle) after putting them on. Talk to Bud - I don't know if he still
makes them but I am very satisfied - and they are easy to work with - one bolt,
two screws and a pin and they are off. After 400 hrs. and 8.5 years only
slightly
dinged up (dumb tax for not being more careful rolling the plane out and
hit a door guide in the hanger).

optimal width to length ratio would be 1:3.7, with the widest point at about
30% of the length. For a 3D fairing things get a bit more complicated. Shorter
carries a higher penalty than longer, so if in doubt just make it longer.
