I tried to mount the rudder, but unfortunally rudder hingles were drilled to 4,8 mm. OK for AN3 bolts but the bushing SC212 and SC217 had a bigger diameter. To drill attachment in fuselage was a minor problem, but the 2 upper hingles on rudder has to be removed. Not space enought to drill when mounted. OK wider holes, new rivets and a quick test mounting. It fits.
