Each designation was assigned an abbreviation, and each design a number within that abbreviation. Several other unnumbered designations were added later. In September 1919, the Army Air Service decided that it needed an organized designation sequence, and adopted fifteen classifications, designated by roman numerals. A variety of both domestic and foreign types were operated, with the latter being the primary front-line types during the First World War. Prior to 1919, all planes flown by the Army Air Service and the Navy were referred to by the designation given to them by their manufacturer.

This list does not include aircraft used by the U.S. For more complete information on the workings of this system, refer to United States Department of Defense Aerospace Vehicle Designations. In September 1962, these were unified into a single system heavily reflecting the Air Force method. Until 1962, the United States Army, United States Air Force (formerly Army Air Force), and United States Navy all maintained separate systems. The United States military employs a designation and naming system to provide identifications to all aircraft types. Prototypes are normally prefixed with 'X' and are often unnamed (note that these are not the same as the experimental X-planes, which are not generally expected to go into production), while pre-production models are usually prefixed with 'Y'. For aircraft in service, see the List of active United States military aircraft. I figure I'm about 50 hours away from air worthy but with the foot of snow on the ground and counting I figure I've got lots of time.This list of military aircraft of the United States includes prototype, pre-production, and operational types. No landing gear problems but I discover that upon tumbling down the runway the top wing will break before the bottom one and the fuse has a weak spot at the wing saddle (very clean break). The result was a perfectly balance plane with good power to weight, awesome sound and a nice slow reliable idle. The box is just above the motor and just fits inside the cowl.

The 120 needed to be moved forward about a 1/4' so I built a spacer with a box for the receiver battery and throttle servo trying to move some of the weight forward. After one summer, I changed it out for an OS 120 Gemini 2 cylinder four stroke with onboard glow (had to lose the dummy radial). The 91 was not enough for this plane even though the instructions almost begs you not to put something bigger up front. 91 FS and had to add a pound of weight in the nose (which just killed me to do). I have a MW Stearman and started with an OS.
