# Mac Muse

The Mac Muse is a Czech single-place paraglider that was designed by Peter Recek and produced by Mac Para Technology of Rožnov pod Radhoštěm. It remained in production in 2016 as the Muse 4.

## 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.
