I've been working with Thomas Kreitler, author of the rotor code in JSBSim, to add some things that will make autogyros possible, so here is the start of the first autogyro for JSBSim/FlightGear. This is the Calidus, a 500 kg MTOW aircraft, with an 8.4m rotor, powered by a Rotax engine spinning a 172cm propeller. More on the real Calidus here.


  1. Hi, I want to use the yours Calidus autogyro model for further development of new autogyros in JSBsim.
    I tested the Calidus model downloaded from: Unfortunately it seems to be very unstable and unrealistically hard to pilot. Is it known bug? Are you able to point me to direction how it could be improved?
