I think the difference may be that you
I saw a notable difference in performance on my first KR installing gap
seals, but it was built using three piano hinges only about 10 inches long
spaced out evenly along the length of the aileron so there was a open gap
from bottom to top.
On my present KR I installed gap seals before I took

Like several others it seems, I tested gap seals as well and quickly decided
they provided no benefit and increased drag. I have scratch built RAF 48 wings
on my KR2S.

paying attention? The KR2 wing is *not* constant chord for most of its span,

Gaps seal?
Anybody know anything about this KR? It looks like it has been around the
patch - several owners in Valdosta GA for example.

And since this message was titled "adverse yaw", it's worth mentioning
that most KRs, due to the differential aileron bellcranks shown in the
plans, eliminate adverse yaw. Takeoffs, climbs, and landings are the
only time that a slight amount of rudder is needed. The rest of the
time the

See http://www.n56ml.com/troy/ for more on gap seals. Just looking at
that big honkin' gap that you get when you build the wings per the
plans, you can guess that there's an

Hi All,
I was just reading an old article by Stu Robinson in the March 1994 KR
newsletter.
In it, Stu points out that the aileron gap serves to increase drag on the down
wing, thereby reducing or eliminating adverse yaw.
However, I also read an article about how important gap seals are
