The Quasar Relief is a series of Czech high-wing, single-place, topless, competitions hang gliders that was designed and produced by Quasar of Dolní Bečva. The aircraft is supplied complete and ready-to-fly.Bertrand, Noel; Rene Coulon; et al: World Directory of Leisure Aviation 2003-04, page 47. Pagefast Ltd, Lancaster OK, 2003. {{ISSN|1368-485X}}
Design and development
The Relief is made from aluminum tubing, with the cross tube and battens made from carbon fibre and the double-surface wing covered in Dacron sailcloth. The nose angle for all models is 132°. The models are each named for their rough wing area in square metres.
The design is "topless", that is lacking a kingpost and upper rigging, instead using a reinforced cross tube for rigidity.
Some models, designated with an "RX" suffix, have a small horizontal stabilizer attached to the keel tube that can be deployed 90° to act as a speed brake for landing.
Variants
;Relief 13
:Small-sized model for lighter pilots. Its {{convert|10.4|m|ft|1|abbr=on}} span wing has a wing area of {{convert|12.8|m2|sqft|abbr=on}} and an aspect ratio of 8:4:1.
;Relief 13 RX
:Small-sized model for lighter pilots. Its {{convert|10.2|m|ft|1|abbr=on}} span wing has a wing area of {{convert|13|m2|sqft|abbr=on}} and an aspect ratio of 8.0:1. The pilot hook-in weight range is {{convert|55|to|90|kg|lb|0|abbr=on}}. This model has a small horizontal stabilizer attached to the keel tube that can be deployed 90° to act as a speed brake.
;Relief 14
:Mid-sized model for mid-weight pilots. Its {{convert|10.4|m|ft|1|abbr=on}} span wing has a wing area of {{convert|13|m2|sqft|abbr=on}} and an aspect ratio of 7.7:1. The pilot hook-in weight range is {{convert|60|to|100|kg|lb|0|abbr=on}}.
;Relief 14 RX
:Mid-sized model for mid-weight pilots. Identical to the 14, except this model has a small horizontal stabilizer attached to the keel tube that can be deployed 90° to act as a speed brake.
;Relief 15
:Large-sized model for heavy-weight pilots. Its {{convert|10.6|m|ft|1|abbr=on}} span wing has a wing area of {{convert|15.5|m2|sqft|abbr=on}} and an aspect ratio of 7.2:1. The pilot hook-in weight range is {{convert|76|to|120|kg|lb|0|abbr=on}}.
