I have been tuning the Armstrong HS1850 to get it to fit on the fuselages. Had to file the wing internal mounting hole a little at a time - but I finally got it to go on snug. Originally it was short of the bolt holes by nearly 3/4". For familiarity I kept the Uni tail on. I pulled the mast back about 1/2" in the tracks to compensate for the additional lift from the 250 extra square centimeters. I got lucky on the adjustment and the 1850 flew fine. This wing did not throw me off on takeoff, and when I got situated there was no need to pump to ride out the waves - nothing but glide from this thing. It is stiffer in the turns (as one would expect from a straighter, wider wing), but it does have a dihedral in it so it does turn better than the GL180
I pushed this foil pretty hard - bigger white wash, some green wave takeoffs and it was totally predictable. I'm going to have to ride this a bit more - and will probably swap out the uni tail for the 232 as there seems to be lift to spare.
