The Graupner Electra is one of the first RC models available in Germany.
Only the rudder was controlled via two heated vacuum tubes and a working relay with a switching star. It was powered by a Taifun Tornado diesel engine with 2.5 cc.
The Graupner material package with printed wooden parts and very extensive accessories
was available from 1955 to 1960 in the specialized trade.
Last year I was very lucky to acquire an almost completed original Electra with almost
all parts and original box.
Only the construction of the vertical stabilizer had not yet been started and some parts of the tailplane were not installed.
It is remarkable how well the model has survived the last few decades in its storage location.

Now it was time to finish building the plane so that I could add it to my small collection.
During the restoration, I made a tew flights with the model, to determine the EDW, the dihedral
of the wings and the center of gravity.
The expected oscillation of the model due to the strong dihedral was confirmed.
As the model is also to be flown for filming purposes, this unfortunately had to be reduced.
