Greetings, here's my PIK info site:

Note I'm talking about the flapped-only version here...I think previous replies have covered most of the ground. Perhaps the bottom line is great value for money, no vices, glides badly with wet wings (common for some gliders with this airfoil), and that landing is quite different compared to airbrakes (but OK when you're used to it). There may well be some variation amongst individual examples so hence the various opinions offered. The PIK factory trailer is great, easily worth half the asking price of the deal! Good luck with your quest, cheers John
