UPDATE: F4U Corsair 1200 mm Project is complete you can download the PDF file below. Assembly instructions.
I am currently in the process of building a 1:12.5 scale Chance Vought F4U Corsair. It has a wingspan of of about 1 meter (39in), and a length of 0.8 meter (31.5in). The design has been done as scale as possible, with the airplane still being a profile design. The design of the airplane is complete. A VERY detailed design log was done for the airplane as part of the Learn to Design RC series of lessons on my website, Eagle-RC.com. The link for the design log is found below: The airplane was designed in the free CAD program DoubleCAD, and imported into Google Sketchup.
Design images are attached. The PDF plans were made in DoubleCAD and detailed instructions of how to create PDF plans make also be found on my website at the link below: The PDF plans for the Corsair are attached in this post.
Build comments and pictures are to come in the next posts! Hope you all enjoy!
I started building the Corsair but drawing all of the parts from the PDF plans onto the depron using the dimensions from the CAD program, then I cut all of the pieces of the airplane out. The build is pretty self explanatory. In the main wing, it is important to get the angle of the wings correct, so I cut the angles from a piece of foam to hold the wing at the correct angle while it was being glued. Care also had to be taken to bevel the pieces of the wing at the correct angles so that the pieces fit firmly against each other and were strong. The wing is reinforced with 4 separate carbon-fiber rods, each connected with a small bent nail. Again, the angle of the bend of the nail is critical for the Corsair, because it is the wings that give it is scale-look. The vertical fuselage is also reinforced with a carbon-fiber rod since it does not have a horizontal part.

Pictures of all of these steps are attached. More building to come!
Eagle, Nice looking Corsair! Do you have any up angle on the horizontal stabilizer? The real thing has about 1.25 degrees.helps to keep the tail up. Regards, Hankg I noticed that the horizontal stabilizer did have an angle while I was working with the 3D views.

I removed the angle in this design in order to make it a little more simple for builders. In the future, I will be doing airplane versions that are more scale and will include all of these details as well as full fuselages. Thanks for your input and your interest! Eagle, That is one of the slickest Corsairs I seen in a long time. I hope it flys as beautifully as it looks. I'm waiting to see if the wing has the strength to support the fusalage.
I had to go to a horizontal piece from nose to tail to help anchor the wing. The large wing on the airplane makes it an excellent flyer but if it isn't anchored to the fusalage you can have trouble. When you get it airborn, take your time with turns etc and watch the wing for flexing. If your interested in a few more sites with mechanical drawings let me know, I'll pass them on. Regards, Hankg.

Regards, Hankg Thanks for comments! The fuselage joint to the wings seems pretty sturdy.but I guess only time will tell.
I am ready for the First Flight, but since I usually fly every new airplane until it crashes, I am enjoying it for a few days. The finished pictures are in the next post!
