tail gear doors puzzler?????
If I understand your drawing, then I wouldn't do it that way. The LEVER theory as explained by Archimedes is nullified. I believe that it is always best to give the gear as much help as possible. If you don't you'll be part of the sagging door crowd! Having the door closing rods at the END of the lever goes against everything I tried to do! 
Not only that but you have springs in the middle. The geometry of your drawing makes the gear work even harder to close the doors. Make the wheel bays as wide as you need to or forget gear doors. But hay, it's your plane what do I know?!! 
On the tail wheel I'm sure you have the room, set it up like the P-40. Brian Taylor did his new P-40 just like the full size, works great.
Anyway you do great work, quite the craftsman!
Good luck with her,
Luke

hmmm.....I think I understand what you are saying. The only reason I thought of having the closing rods near the end was for greather throw in opening and closing.....but come to think of it now...that part is irrelivant because you can adjust where it connects to the door, closer to the hinge line= less distance traveled, however greater force to move. Maybe I'll make up a mockup system and see if it works first.
Thanks for the compliments.

Doors
JohnVH, Thats exactly what I am going to try to do.. On the P-47 the rods attach to the gear very near the strut.. on the doors the rods attach about mid-way the depth of the door. The rods are attached to universal joints at the gear strut and into ball end receivers on the doors.. Seems as tho we could do the same thing using ball links on the gear and doors... BobH.
