Hi Bob, Funny thing about Idasail... A few months back I called twice, got hold of a production person who said Joe was to busy to talk on the phone. Took my number and promised me he'd call (never did). I Emailed several times, mentioned that a couple of people on the MSOG had expressed interest in the HDPE and specifically beaching rudders. After beating my head against the wall I posted my frustrations with his company. It all started with a post of wishing to replace a rudder on the MSOG. I've seen several of the Potter factory rudders made by Idasail. The work is excellent, the fairing very even and the posts from the Potter Group say they love the rudder. Please post you final results with Idasail. I know there are people in the group that will be interested Bill SF Bay M-17 #496 "Tiperary"
