I have a Kitfox 3 with 4 wings I recently bought in Alaska on floats. I have brought it down to Arizona and have converted it to taildragger. Went out to taxi in prep for test flight and realized the seat shell is sagging far enough to touch control rods. Has anybody else run across this? I thought it was just my fat butt then after disconnecting the seatbelts and removing the seat pad i found I could push down on the fiberglass shell with my hand alone and force it without much pressure to touch the control rods. Any ideas?
