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.
