By a happy coincidence two modelers of the old and new generation were brought together: Hans-Martin Riehle, retired model builder and René Marschall, Planeprint mastermind and model flyer for many years. Hans-Martin Riehle learned about Planeprint and saw the almost endless possibilities that lie in 3D printing for model making. When he began planning an all-fiberglass eagle model in 1998, he had no idea that more than 20 years later, a new technology would be available that could produce a flyable eagle model that was half the weight in a very short time. 


The beginnings in 1998 were time-consuming and complicated. Still without the Internet, Hans-Martin Riehle had to make numerous studies, in nature and in zoos, to capture the eagle in pencil sketches in order to be able to represent it as true to nature as possible. The entire construction of the master model and the negative molds was done using conventional model-making methods and took until 2002. The most difficult part was the winggrids (feathers on the wingtip), but they also contributed significantly to the model's lifelike appearance. A good 300 hours of work went into his model before the first flight.

When Hans-Martin Riehle contacted Planeprint to discuss the possibility of reworking the Eagle, the course was set for the Planeprint Eagle. René Marschall, always looking for interesting models for his flight enthusiastic community, saw the potential for a new project. Besides, the Golden Eagle is Tyrol's heraldic animal and can even be seen flying over the mountains of Innsbruck from time to time. 


The Eagle was to be given a lifelike, complex shape through the outer skin and a bionic inner construction. Planeprint uses a hybrid construction method of PLA and LW-PLA (Lightweight-PLA) for the first time in this model. The leading edge of the wings and the front fuselage area were printed with the more stable PLA, but everything else was printed in LW-PLA. The low flight weight of 1150 grams makes the CG very easy to maintain. The parts for the LW-PLA were designed completely differently to get the retract to almost zero.


3D printing shows its full performance, especially with organic shapes, and so anyone can print out their own Eagle and glide over the hills and mountains with it.
