The Me 109 was the main fighter for the Germans in WWII. They made thousands of them.
They also made some unusual and very advanced designs, the Fi 265 was a gyrocopter.
They served mostly with the WWII German Navy, but some served with the Army also. I built two at once, one for each service. They made fewer than a dozen, but they were well liked. There were plans to make thousands of the follow on version, but due to production problems, it never happened.
