hello to all!
I would like to know if the flight patterns present in outerra can be applied to aircraft not "conventional" as: ch 47, harrier, osprey, etc. etc. Kamov Ka 50. If yes, which parameters should be changed and what are the files to edit!
Merry Christmas!!!

Flight dynamics is driven by the JSBSim library, and as long as you are able to create or modify the flight model using JSBSim tools or by editing the FDM files directly, you can use it with aircraft in Outerra. You can see the files in the MiG29 package directory under aircraft and engine directories, but you'll have to consult JSBSim manuals to know how to modify them.

Thanks Cameni! Question: I saw the program Aeromatic! Interestingly, it is applicable to helicopters?

I don't know .. that's something to ask JSBSim people, I guess.

Aeromatic only works for airplanes, at this time.

I thought I would mention here that for JSBSim questions, please consider asking on the JSBSim developer mailing list, whcih can be subscribed to at www.jsbsim.org. Or, if that doesn't work, you can email me at jon@jsbsim.org. Due to time commitments, I may not always reply very quickly. For specific JSBSim questions, the mailing list works best.

Thanks for the reply!
I joined the mailing list now and I wait for users to ask questions about helicopters such as the CH47 / or counter rotating rotor models as Kamov, but also for convertiplanes or harrier!
in outerra I inserted a eurocopter as 350, flying, although I realize the script for the moving parts, rotors doors cyclic and collective, but I made reference to the flight model of health evaluation and then the cobra. it is clear that a as350 flying with the performance of an apache is unrealistic. The question is, without a dedicated rotary wing Aeromatic you can change the engine ah1 to bring it to the characteristics of different helicopters?

Are there available helicopter scripts in flightgear?

i don't know!

It may alter the following parameters as cards of various techniques helicopters:?
