That can be adjusted very easily. Open up $FG_ROOT/Aircraft-yasim/j3cub.xml, find the vstab element, then play with the "lift" attribute on the the vstab/flap0 element. The number is currently 1.5 -- if you make it higher, the rudder will become more effective. > I also noticed that the climb was very laborous Vx is supposed to be 55 mph and Vy is supposed to be 65 mph; however, I'm getting a good climb rate at 55 and an anemic one at 65, so the model clearly needs a little tweaking.

What glide speed did you use? I think Vglide is supposed to be around 60 mph, but I'm not sure that's where it is in the model right now. > On another note.

I'd rather fix that in the 3d model. I'll be happy to put in a patch for the differential aileron deflection, though.
