Dolní Bečva Village in Vsetín District of Zlín region

Dolní Bečva is a village in Vsetín District, Zlín Region, Czech Republic. It has a population of 1,900 (2015). Located along road E442 between Rožnov pod Radhoštěm and Prostřední Bečva, the village is nestled in a valley of the Beskid Mountains. Dolní means "lower" in Czech, and the Bečva is a river that snakes through the village. Dolní Bečva is a popular summertime destination for athletes and nature enthusiasts, who visit the village to go hiking, bicycle riding, fishing, or mushrooming.

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. [1]

The design is "topless", that is lacking a kingpost and upper rigging, instead using a reinforced cross tube for rigidity. [1]

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. [1]
