Vintage RC Helicopters - Kalt 50 Baron

KALT 50 Baron

Kalt 50 Baron (1979 or earlier)

1981 catalogue   1985 Catalogue

Also known as the CP Baron and following on from the original Baron; developed to take the new 50 size helicopter engines with any of the collective pitch rotor heads with autorotation as standard.  The Baron body was used but with an extended boom in order to accommodate longer main blades and heavier duty landing gear in order to take the increased weight.  In line with Kalt's policy the kit was provided without a rotor head and the customer chose the specification of the head themselves.  belt start but an option available was to fit a bottom starting cone to the OS50 engine.

Kalt 50 Baron review  -  From April 1981 by Bill Burkinshaw for the UK magazine RCM&E.

Kalt already had a model of the JetRanger with its own dedicated mechanics however, it was also decided that the first of Kalt's range of 'hang-on' scale bodies would be the JetRanger with the internal layout redesigned specifically to take the 50 Baron mechanics with either the standard 50 size engine or a larger 60 size for more 'sporty' performance.  This model was later followed by the Long Ranger and Bell 222 which were also suitable for the 50 baron mechanics.

1982 Advert (UK)

The Baron 50 had proved very popular and was thus available in four formats to cover all applications, Standard and Super Aerobatic, Custom and Flybarless; these options were provided by supplying the model with different rotor head arrangements.
