JSBSim Flight Model

[ghost]

Hey there ;) I think it might be time to merge the JSB FDM into master, as it's quite realistic by now. Please look if you receive any errors and problems.

Hi @D-ECHO thanks for this and sorry for the slow response. I like the FDM, in some respects it's already better than the Yasim one.

Pros:

• Realistic mushing stall, finally!
• Slower, more realistic acceleration in a dive.

Cons:

• The controls will need tweaking, in particular the elevator is a bit too efficient/sensitive.
• There is way too much adverse yaw. IIRC if you just use the stick without rudder, then from the front pilot's perspective the glider appears to roll around the yawstring or a point just above it.
• Aerotowing (Ctrl-O) doesn't seem to work.

Despite these drawbacks I'm happy to merge this as it doesn't conflict with the Yasim model. I'll try to find some time to make some tweaks eventually.
