Great Job, Barry on those flaps. I have the split flaps on my KMP Hurricane and sometimes I use them and sometimes I don't depending on the head wind when lending. I also had a 60 size World Model Spitfire with flaps and used them all the time. On both of my planes with flaps, I noticed that as soon as the wheels touched down, I would reset the flaps to neutral and the tale would set right down....as long as the flaps are deployed(down) they would put pressure on the plane to lift...but once they are down on touch-down the tail settles real nice and the plane slows down normally. I really like the job you did in modifying the trailing edge on the Cermark Spit. I am tempted to do the same, but I have never done that kind of modification. It looks difficult!
