ZLIN SAVAGE BOBBER
Fully 3D printable RC airplane developed by René Marschall
Wingspan: 900 mm (35.4 inches)
Flight weight: 490-550 g
5-channel: (gas, aileron, elevator, rudder, flap)
Material: PLA approx. 270 g/Flex approx. 40 g
Motorization: 2S or 3S (Shockflyer equipment)
5 x pico servos needed
Printer space of 200x200x200 mm needed
Note: The slicing works only with CURA! look here why…
Our goal: to use simple and inexpensive remote control equipment of common Shockflyer models.
These model aircraft are powered slowly using a large and flat propeller for gradual incline.
This requires a type of aircraft that has good-natured and slow flight characteristics. We immediately thought of looking at STOL (short take-off and landing) planes. It was a particular challenge to develop the Savage Bobber with its steel lattice hull as a printable rc model.
In order to maintain the chosen engine, the wingspan must remain rather low and was thus defined to 900 mm (35.4 inches). Based on this, it was now our task to design a correspondingly light but also stable aircraft. Planeprint’s approach is to be able to replace and service as many parts as possible. This makes the design process more complex than working simply with bonding glues.
We aim to develop models that are suitable for everyday use and that are also easy to repair.
Due to its compact size, the PLANEPRINT-1-wall-construction (also the inner workings of the wings and the tail is printed with only one wall thickness) and the use of a high-performance airfoil (S3021), we can achieve a wingload of just under 38g/dm2 which allows optimal prototypical flight characteristics.
Due to the softly cushioned landing gear and the quasi original balloon tires (printed from Flex-TPU), with the flaps set and the motor running minimally, landings will be absolutely spectacular – just like in the real STOL aircraft! Overall, the impression of the plane in flight comes very close to that of the legendary original.
Basically, we recommend the SAVAGE to experienced pilots, with practice in takeoff and landing (with set flaps and playing with the motor). Handling the plane even without landing gear is easily possible by throwing it by hand and landing it on a grass runway.
