Default RE: China Model Productions O-1 Bird Dog in VNAF Finishing and Flying

Dai Phan-- the 'Dog is looking great. This is a color scheme that I have considered fo mine, but I think I'm gonna do a camo version. It's interesting what you said about the other version of your plane not having any dihedral. Cessna experimented with taking the dihedral out to see if it improved roll rate, but it didn't, so they left it in, only changed one plane by shortening the wing struts, but changed it back. I'm surprised to see the dihedral in yours starts way out on the wing; it should start at the wing root, but it's no matter. I only hope mine looks half that good.

I looked up the tail number that you have the decals for. That plane was built May 14, 1952. It started "life" as an "A" model for the National Guard, but was later modified to a "G" model in August 1966 and its last known location was in Vietnam. It may well have been destroyed, but there was no note of it in the book; however, the book says that such records are incomplete, and many that were destroyed have since been salvaged and rebuilt or restored.

The difference between an "A" and a "G" model is that G models were rebuilt from A models, modernized and beefed up. The A model had a max gross takeoff weight of 2100 pounds, the G model had ratings of 2400 or 2800 pounds, and were identical to "E" models which were built initially to the 2400 gross wt. All had the same engine and look alike, but have subtle differences, such as closer rivet spacing in the wings of the heavier planes, the flaps on A models were mechanical, all others have electrically operated flaps. You get the picture. I don't think anybody is going to count the rivets on yours, it's gorgeous. BTW, all the info I got out of the book I told you about earlier. Keep the posts coming!
