Mac Muse

Design and development

The aircraft was designed as an intermediate glider and paramotoring wing.

The design has progressed through four generations of models, the Muse, Muse 2, 3 and 4, each improving on the last. The models are each named for their approximate wing area in square metres.

The manufacturer claims a glide ratio of 9:1 for the Muse 4.
