Rollason / Luton Beta B2


The Beta is a single seat sporting monoplane of all wood construction. The wing employs an NACA23012 aerofoil section and consists of a rectangular centre section and tapered outer panels. The wing is made up of a single main spar and auxiliary rear spar, wood ribs and plywood covering. The mass balanced wooden ailerons are fabric covered. Flaps are optional. The fuselage is a semi-monocoque structure consisting of elliptical wooden frames and plywood covered. The cantilever tail unit has a ply-covered fin and tail plane and fabric covered control surfaces. The fixed undercarriage has rubber in compression shock absorbers on early models, but spring steel legs on later models. Fuel capacity is 10.5 Imperial gallons. Four versions of the Beta are available, the basic difference being the engine fitted.
