Hi all, I am currently trying to build a Piper PA34 Seneca for FlightGear. I started creating a 3d model and have now a model with some animations implemented. Animations are the usual stuff: elevator, aileron, rudder, gear and cowl flaps. It has a somewhat ugly texture, but got a cool tail-number. But look yourself: http://www.t3r.de/fg/Seneca-screen-001.jpg
Now I tried to do the FDM and I'm somewhat stuck. I first tried YASim, then JSBSim by lerning from existing Models (c310, c172), adjusting some values according to the Seneca's manual and endet up with a YASim Model where the solver loops endless and a (at least) flying JSBSim Model with a absolut unrealistic performance. The Plane takeof speed is some 140knots with a rate of climb of 70fpm which is far from the real thing. Long intro for my question: What is the best FDM to use, when I have the airplane manual with its dimensions, performance data, mass-and-balance section and with the ability to actually fly the plane and get the real data like "what indicated speed at what pitch with which power setting at altitude 8000ft with ISA?" How do I convert these real-life data into a FDM config-file? If you like, here is the original after which I try to build the model: http://www.littlewing-air.de/fotoshow/index_fotoshow.html Greetings, Torsten ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
