25 Kirby Kite 1’s where built. Of which 8 survive, one with out wings. The design used many Gruanau Baby 2 fittings. About 15 Kites where used at Ringway then to Haddenham. One Kite was built for the RDF(Radar) trials at Christchurch in 1940. This had cable runs replaced by oak push pull rods.The Camouflaged Kite BGA 400 at Old Warden yesterday has only the wings of the radar Kite. The rest of this Kite was lost during the war. BGA 400 was restored by my father and myself in the late 1980’s early 90’s. I was there yesterday to help rig and derig the Kite. Which is now owned by a group at Haddenham. I have the prototype Kite and the original BGA 310.
