MULTIPLEX History
Chronology of milestones in the RC and model sector
RC
1958
Foundation of the company S. Kußmaul, which later became MULTIPLEX. Production of components for radio remote controls (e.g. for the Engel company from Knittlingen). Soon the first own single and multi-channel tipping radio controls followed. For the first MULTIPLEX remote control, a bread tin served as the "housing"!

1963
Presentation of the MULTIPLEX 10, a proportional radio remote control that worked on the basis of the "Vielton" technology.

1964
With a prototype of the 101, Kurt Bauerheim achieved a remarkable 3rd place in the RC 1 class world championship in Corsica.

1965
Presentation of the MULTIPLEX 101. It was the first radio control system in the typical belly transmitter shape to be mass-produced in Germany and which worked according to the so-called PPM system (Pulse-Position-Modulation).

1967
Presentation of the Digitron series with versions of 2- 6 channel remote controls. Reliable and durable, in use for many years on many sites at the time.

1971
Presentation of the legendary MULTIPLEX ROYAL. A benchmark in remote control technology at the time. Special features:
Hand-held and console transmitter in a material mix of plastic and metal.
