The MO-1 has the ideal shape (square cross section fuselage, lots of wing area, ample tail plane areas) to perform well in Carrier competition. Very simple to build, especially for CL-1&2 (scale carrier classes) and you can build all 3 AMA Carrier class planes off of one set of plans. Plus there is not that much documentation about the plane and they are (to me) a bit ugly so I don't think they are never ever looked at closely. They do have ever attribute that the carrier flier is looking for.
