I just ordered one - Idasailor unifoil rudder
My H26 rudder aluminum plates just failed on me, probably due to crumpled mid-plate spacer. The upper assembly has very noticeable flex in decent and above winds. I tried putting in a new spacer, no luck, then a long piece of wood as a spacer. No luck. the plates till flexed. I already had an H26 Idasailor rudder which can't be used on the whole 9-yards blade-assembly-tiller Idasailor unifoil replacement. If you need a blade to go with your existing upper assembly, I'd be willing to sell it. I was very happy with it. At any rate, check your spacers especially the mid-plate one. I think its shortened spacing condition wrecked my plates. Hunter doesn't stock the plates and said it would cost over $500 to fabricate replacements. I'll try to post my review once I get the unifoil.
