Kalt GS Baron II

1987 Catalogue

The KG-22 engine had proved to be marginal in performance and so Kalt carried out development which significantly increased its output resulting in the designation KG-22S.  This more powerful engine fitted in a modified 50 EC resulted in the Mk2 version of the GS baron with a reduced main gear ratio to increase head speed along with autorotation as standard.

Any one who owns a Kalt 50 or gasser knows how hard it is to get parts. Had a tail boom strike on my gasser and no boom to replace the original. I got over this by fitting a complete Robbe Millennium/Futura tailboom and drive complete. The drive just fits straight on the pinion output shaft (Without modification), leave out the black Kalt boom clamps and clamp the larger Robbe boom straight in. A much better system than the old wire drive and a much better and more efficient tail rotor assembly. I am lucky in the fact I had all these parts to hand (all second hand) so I did not have to buy new and hope they would fit. I can now use longer 710mm blades due to the longer boom.
