: Sanding rather than waxing a PIK 20 Question Has anyone have info on this I was told that when this persons PIK did not clime well he would sand the wings with 400 grit . I had a PIK-20d and the performance loss with bugs or rain was memorable. The drag increase could be heard and the sink felt before rain was wisible on the canopy. I never waxed the glider, hoping that might help the droplets to lay flat on the wing. The urethane finish also didn't need to be waxed to protect it. I always wondered if a thin layer of some sort of surfactant (like soap, maybe?) might help the problem. Never tried it, though... I finally solved the problem by selling the PIK and co-owning a LAK-17a. It has a urethane finish for easy care and flies just fine in the rain. It also does't drop wings, handles great, has automatic hookups, and has outstanding performance. Yes, it does cost a bit more. -Bob Korves |

I owned the Pik 20B for three years now. I usually never fly in rain since
there is never some around. The horror stories narated will only mean that my glider would descend like a Cessna 150 in rain. No big deal. I have had quite a bit of bugs on the leading edge as we tend to manufacture them in Canada. I pratically did not see any traumatic difference in the flight characteristics. Finally, I would not worry one bit about this wounderfull glider. In fact, I wax it every spring. It gives it a great look and is much easier to clean after a long day. I would not spend any time sanding the wings unless you have a serious bump bear the spar. I see that a fortunate fellow flew his Pik on the Ridge in april for 1 000 km. Can't be that bad, would you not agree? Best regards, keep the blue side up! Marc Arsenault "74" |
