Re: [Flightgear-devel] Yasim, Quadcopter and MatLab
Thanks you very much. Have you already used FlightGear to do Hardware in the Loop verification? Best, Julien.

Re: [Flightgear-devel] Yasim, Quadcopter and MatLab
Hi, I've just used you model. But I have few bugs. The first one is that the quadcopter stays under the ground when I launch FG. The second is that I cannot control it with usual keyboard keys. Any idea? Best, Julien. PS: Sorry if my questions are a bit boring... It's the first time I do such things.

The first one is that the quadcopter stays under the ground when I launch FG. there is no 3d-model for the quadcopter. It is very small, much smaller than most other flightgear aircrafts. The second is that I cannot control it with usual keyboard keys. All commercial quadcopters have gyro stabilization, but this one has none (should be not much work to program one in nasal or using the autopilot).

I thought JSBSim cannot model rotor based aircrarft. Some one knows when this will be released? Julien. Hi, Julien, Thomas Kreitler donated a rotor model. That was incorporated into JSBSim. There was also an Apache AH-1 model that worked within FlightGear with the new JSBSim rotor model, I believe. It's still in a beta stage. We'd like to see that model be generalized a bit more. Thomas believes he will be able to do this next month. So, there are still some things that need to be done with it. You can see the code in the JSBSim project as FGRotor.cpp. Jon attachment: winmail.dat-- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
