The design is based on Auto-G2 by Durafly which is extended by PX4 autopilot. The Auto-G2 model is discontinued and is not longer available. Adequate substitute is the 3D printed TF-G2 autogyro kit.
The original purpose of this model is the training and testing of PX4 software improvements, prior the autogyro airframe has been sucessfully merged to PX4 airframes.
