[Flightgear-devel] New aircraft: SF-25

2011-08-15 Thread Viktor Radnai
Hi all, Athanasios Goritsas (cc-d) created a nice Falke 3D model with a basic Yasim profile, based on the aircraft he flew with. I would like to develop his model further (I'm doing my PPL on the real thing atm). We would both like to see it in Git (under a GPL license), maybe more people

No, I mean that it is possible to both overwrite properties within FlightGear directly on to use a Nasal script as an interface to overwrite those properties. You can browse the LinuxTrack source code for examples, the parts specific to FlightGear are here:

BTW, you can get a pretty good idea of where the CG is on a plane from the landing gear position. On a tail dragger the CG will be slightly behind the main wheel. Too far back and the tail won't have enough authority to lift for takeoff, too far forward and the plane will nose over when

Hi, the correct cg for a SF25C is 0.143 .. 0.334m behind the wings tip (measured 0.52m from the center line). Regards, Maik am 15.08.2011 22:07 schrieb TDO_Brandano -: BTW, you can get a pretty good idea of where the CG is on a plane from the landing gear position. On a tail dragger the CG

Vik, Based on Maik's CG information and a little nosing around for performance information online, I made an el-cheapo quick and dirty FDM: http://ltts.crlt.indiana.edu/grn/flightgear/sf25b-yasim.xml Feel free to use it, lose it, abuse it, or whatever. It's a bit tricky to takeoff and land,

OK so I tried to trick FG several different ways, none of which really work, I tried to get it to send data to one serial port and receive it on another that sort of works but after about a minute or so FG just stalls and stops sending data, and basically stops responding to all command inputs.
