Graupner like Ripmax of the UK was primarily a distributor of modelling goods but did market a small amount of 'own brand' goods. In the late 60's they were actively involved in promoting the 'race' to produce a Radio Controlled Helicopter and though Dieter Schlüter won this race, a number of other builder developers were very active. One of these was H Demuth and unlike Dieter, who produced the simple fixed pitch Hiller head, he developed a more complicated collective pitch design. In collaboration with HB engines (Helmut Bernard Engineering Works) he developed a scale model of the Bell 212 which was then taken under the Graupner 'wing' for final production and marketing in 1973. This model turned out to be the better handling machine of the initial German group of three helicopters (Schlüter Cobra, Kavan JetRanger, Graupner Bell 212) primarily due to a longer develop period and the experiences of the others being utilised to good effect.
Following on from this the next model in 1975 was unique at the time in that it was basically a 'Super Airfix' kit which resulted in a good rendition of the Bell 47G. The original Bell 212 rotor head had the drawback of limited pitch range but proved to have very good control characteristics and so it was developed further into what was later to be termed as 'flybarless'. The revised mechanics followed the trend for the time in being pod and boom format and in 1979 was available with either a full scale Bell_222 fuselage or with a 'semi-scale' Bell 212 body for training / general flying purposes; this latter being known as the Bell Trainer.
