I have a bunch of numbers that I've been collecting since first flight, but the biggest surprise (shouldn't have been) is the difference in cruise speeds that the gear fairings make.
With no fairings, at 2600rpm, 6500', TAS 152kts.
Gear leg fairings only, 2600rpm, 6500', TAS 162kts.
Gear leg fairings and wheel pants (no intersection fairings), 2600rpm, 6500', TAS 174kts.
That's +22kts!! I'm really looking forward to the full faired number!!
The worst part about the pants being on now, is that it increased my heavy left wing...
The difference with fairings

I found once i got going over 170kts, mine really want to roll left. Finding the aileron sitting up ~1/8" and then dropping it, mine is hands off now.
Congrats on finding the speed secret.

Chad,
I remember my first technical counselor, Randy Lervold, writing a report about how much the intersection fairings ALONE made a difference in his stall speed as well as top speed. It's amazing how draggy things are without these fairings. His plane stalled at a lower speed with all the fairings on, if I recall correctly, which of course affected his landing procedures.
I would be very interested in hearing about the other end of the speed envelope as well. What do these fairings do to your stall speeds? Have you thought about that, or logged any numbers on that?
