Pitts Model 12

Designed by Curtis Pitts, the Pitts Model 12 is a 2 place fully aerobatic biplane designed specifically around the 360 HP (400hp) Russian built Vedeneyev M-14P (PF) radial.

In March 1996 the completed Pitts Model 12 was test flown and earned the nickname "Macho Stinker" as part of the long line of Pitts prototypes.  The name "Bolshoi" is no longer used. Professional pilot, airshow performer, Ben Morphew performed all acro test flights in the model 12 and decided he wanted one and contacted the Kimballs at Jim Kimball Enterprises for them to provide some of the components.

The type was available as plans built, HP kit, or factory built Model 12S by Jim Kimball Enterprises.

All are two seat except the 12S, which is a single seater. All are tube and fabrice, fully aerobatic, and powered by the M14P or M14PF engine.
