The Alpha Contest was introduced in 1975 and is one example for many radio systems made by Simprop Electronic, a German company. The transmitter shown is the basic 4-channel version with cross-type sticks, there were also other versions with additional switches or slider controls. Despite being more on the expensive side of the pricelist, the Simprop systems were very popular in Europe but also could be found overseas. Mainly used for radio controlled aircraft models but also seen in RC cars.
The case was made from aluminium with moulded plastic side panels and is typical for most Simprop transmitters, introduced with their Digi series back in 1968 and still used in the 1980´s. Large internal GE batteries provided enough juice for a full day of flight or car racing. The stick mechanism was a new type introduced with the Alpha Contest series, very smooth and high precision, we think superior to most other transmitters.
We are showing the Alpha Contest as we personally used such system at some point, also we want to show the roots of a very special transmitter designed for car racing.
