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, especially in any kind of crosswind-- it takes a fair hand on the rudder. It also likes to glide and glide once it gets close to the ground, so you'll definitely not want to approach over 50 kts or you'll never get down. I often side-slipped to help me get down. I disabled the linkage of the spoilers with the wheel brake-- According to the book, brakes are engaged only on the maximum spoiler setting, but I got tired of nosing-over when I landed. ;) You might want to restore that. I didn't try to match sink rate to real, I only tried to get the speed range within reasonable norms and bring control surfaces effects to something that felt reasonable. You might want to mess with the spoiler settings, maybe increase the drag a bit, as the handbook says they're pretty effective, and I tend to err on the understrength side. I'm not a pilot, so definitely feel free to disregard anything I did. -Gary, aka Buckaroo ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.
