If you leave the plane out in a hail storm the entire airframe will be like a golf
ball and ought to go faster right? the resulting backspin will reduce torque
and p-factor effects too.
Disclaimer: leaving aircraft in hail storm may result in other undesired results...

Sounds like a "poor man's" BLC (boundry layer control) like we had on
the F-4. It only came on when the flaps / slats were down / out, but did help
reduce stall speed in the landing configuration by helping to keep the airflow
attached. I suspect he is using some sort of "turbulator tape" installed span
wise on the wings to achieve the same effect. It will probably lower the
stall speed AND decrease the drag at top end therefore resulting in a higher cruise
speed or same cruise speed at less power. Should be a win / win situation.
Brian, I left a roll of one type of this tape with Nick when I was there
last fall. It was in the box with the gap seal material roll. There are several
types of turbulator tape - the one I left was more for use in front of control
surfaces to make them more effective - such as rudder, elevator, and ailerons.
For you golfers out there, it apparently is the same principal that makes
dimples on golf balls the best design.

Hey, great idea. You might also want to try that hail storm idea on one of
your Corvettes. Should help you with top speed and better cornering during
your next auto cross or gymkanna.
Just my $.02, your mileage may vary.
