how sensitive the elevator was. The rudder on my plane has very little throw sense it hits the elevator . If your Pfalz rudder was designed after the Fok than I suspect the cut out was to give the rudder more throw and help the aircraft track better in turns
I appreciate the comments ... kind of info I was phishing for. Sounds like I need to limit the throw of the elevator, and make sure that the rudder movement is effective. I did remake the lower/forward part of the rudder where I had a problem with it banging into the pylon strut. However, I still have a problem that my rudder cutout does not allow anough clearance of the elevator. I plan to decrease the gap of the elevator to fuse, which I hope will help.
Been lately workin on the undercarriage part. Made brackets to hold the l.g. struts which also have the slot for the axle to move in. Trying to make it as much like the original... there are a lot of good pictures in the Windsock #59, but it's still not easy to be sure of the details.
The brackets are each made of two folded pieces of tin. I am going to use a streamlined shape K&S Al section for each strut. But for development purpose, I sanded off basswood pieces to approximately same shape and size as the Al. The tin pieces are shaped around the struts using some steel brackets and the vise, then soldered together. The brackets will be trimmed up and lightened later.
