First, Chris at Falconar Avia explained this to me but I'm still wondering... The F 10 I'm building is designed a little stronger and a bit bigger than the D9 and there are other changes too. So I was scratching my head as I got ready to glue up the bottom (aft of rudder spar) rib... it is 30 inches long... the rudder soar is 46 inches long.. so looking at the plans the rib angles from the spar to equal 4.5 inches away from a plumb line from top. Imagine the spar is laying horizontal on the bench, the rib attached at the bottom going vertical but angling left... so the joint required two bevels, one on the spar and one on the rib to make a clean joint were the 1/2 X 1/2 spruce meet as well as the 1.5 mm birch ply. Is this normal for all rudder to have this or is it more common for tail draggers to give the rudder more ground clearance? Whew
