Well guys glad to see that you took my advise on beefing up the landing gear and using the Robart hindges which is the medium ones. The way I beefed up the landing gear is by adding a second support wire to the back of the landing gear strut and angleing it back to the wing then make a short 90 degree bend then bend again to a hole in the block of hard wood at the back of the landing gear. I haven't measured it for sure but the block should be about two or three inches behind the gear. If you do it rite the wheel pant cover will hide this support quite nicely. If you think it will help use the gear wire cover as a template to get the rite angle for the suppot wire and location of the hard wood block.
Barzini the plastic covers that you are questioning about go on each side of the rudder. On mine I made my tailwheel free float instead of tying it into the rudder. Also if you guys can fabracate better brackets for your flyig wires do it now the metal ones are sharp and to me a little testy to keep trying to hook the flying wires to. On the brace that goes from the fuse to the wings I used a wire at the bottom of the suppot down into the wing to a wood block. Then on the top of the suppot I used small screws to attach to the fuse. I hope that this will help you guys and I will try to give you more info if you need it. Sorry I dont have a scanner other wise I would post some pictures of what all I have done to mine and what my birds look like especially the one I converted to a bype.
