From: "Carl Cadwell" <CarlC@Cadwell.com>

First, my thanks to Doug McAlister who first did this and put me on to
the idea.

I installed gap seals on all the control surfaces (top and bottom of
ailerons and elevator; both sides of rudder) and trim tabs (on the
non-hinged side) for the rudder and elevator.  I gained 6 kts IAS at FL
240 and 250.  This is where I fly most of the time and know my numbers,
power settings etc.  The lowest number I see is 6 kts IAS increase to 8
or 9 kts.  So I am claiming 6 kts.  I have taken 6 flights now with the
same results. =20

Doug tufted his ailerons and observed flow that used to separate ahead
of the ailerons now separates part way down the ailerons. =20

The handling seems to be the same with perhaps (maybe) a little more
roll response at slow speed. =20

TAPE00051	MYLAR PROFILBAND 30mm 15M	for elevators and
ailerons
TAPE00050	MYLAR PROFILBAND 38mm 15M	for rudder
TAPE00090	TESA SAFETY TAPE FILM 25mm or 30mm=09

The mylar can be ordered in the roll or by the foot.

Layout =BD wide section on the trailing edge and sand lightly with 400
grit.  Clean. =20
Apply mylar.  Apply safety tape lapping 1/2" onto the mylar.
Do not sand on area under safety tape.


To maybe prevent icing from building up on the rudder counterweight and
preventing elevator control, I also put 2 small pieces on my horizontal
stabalizer that covers the leading edge of the counterweight.
Thankfully, I have not accumulated any ice to test if this works or not.
A future report if this happens to help.
