Ventus bt handling

Regarding the Dick Johnson "recommendations" on "heavy" Ventus aileron
fix, where can these be found? *I had no luck with both SSA search and
google search. *I'd sure appreciate finding this info.

The wing skin on the Ventus (and many others) can start to rub on the
flaps and ailerons. This will leave black rub-marks on the controls.
The fix is to slide 60 grit sandpaper in the gap with grit up (wing
side) and run it back and forth while moving the control up and down
until the control moves freely in all positions. Do about 3 feet at a
time on both sides of both wings. It will take a good afternoon to
accomplish. Wear gloves as the sanded edge will become sharp as a
razor. Bend the sandpaper up on the last strokes to round off this
razor edge.
Have fun,
JJ
