| edtherenderman | Scratch Built McDonnell XP-67 | Build | 20-Jul-20 08:40 |  | | Views : 342 | | Now that the Hannover is complete, time to start something REALLY different; a McDonnell XP-67 MoonBat. This is not a very well-known aircraft. Only one example was completed and after flight tests, was found to not be significantly better than other aircraft at the time. Part of the problem was it was being used as a test bed for a new engine being developed by Continental. The engine didn’t develop the power expected, and the aircraft design had a lot of overheating problems. An example of trying to do too much at one time. Plus, the aircraft didn’t have the stability one would want in a gun platform, pilot visibility around the engines was poor and ground handling was difficult because the pilot couldn’t see the wingtips. BTW – if you like old, weird machines, try out the https://oldmachine press.com. I love this site! I found a plan for the aircraft on Oz. They are for a 60” R/C so I scaled them down to 1:24 which gave me a wingspan of 27.5 inches. I then converted them so that I could cut the parts on my 2D Laser etcher/cutter. It took a couple of evenings to convert the plans and about 4 hours to cut. I use almost an entire 6” x 36” sheet of 1/16” balsa. Over the 4th of July weekend, I started assembly. This picture is one side on the board. This is a pretty complex aircraft shape and I found that I needed to add a new former and a lot of stringers because trying to “skin” something at this scale will be more complex than the original 60” version. |
