Full Description

HW-4 FLAMINGO (3.5M) – RC2215 – World Class Designer Chris Williams turns to a Brazilian sailplane dating from 1947. The HW-4 Flamingo was a one-off sailplane built in Brazil in 1947 and described in Martin Simons’ book ‘Sailplanes 1945-1965’ as ‘elegant’, having a relatively high aspect ratio wing, coupled with a classic gull break. Chris Williams has been campaigning a larger 1/3.5 scale version for some years now, but after the success of the 1/5th scale Petrel (full short kit also available from Sarik Hobbies RC2207), producing a smaller version of the Flamingo was a no- brainer.
Just like the Petrel the fuselage is relatively heavy, being plywood-clad, whilst the wings are super-light. It’s this combination that allows these models to fly in just about any conditions, regardless of wind speed.
