Specifications

Performance

Other

The Cherokee II was introduced in 1956 specifically for amateur construction from plans. The entire airframe is covered in fabric. Upper surface spoilers control the glidepath, and the landing gear is fixed. Many examples vary in detail. The design was further developed by several builders including the Cherokee RM by Terry Miller and John Ree with a 13.4 m. / 44 ft. span wing with NACA 64(3)-618 airfoil which increased L/D max. to about 28, and the 15 m. Leonard Annebula which has Prue type trailling edge airbrakes and a claimed L/D max. of 31. A Cherokee RM belongs to the National Soaring Museum.

Specifications

Performance

Other

This distinctive pod-and-boom sailplane was designed to explore a fuselage with reduced wetted area; to learn more about the effect of a gull wing on hands-off stability while spiraling; and to investigate low-speed performance characteristics as affected by unusually wide NACA slot-lip flaps. The sole Ibex belongs to the National Soaring Museum
