Yes, but you can still control most aircraft relatively OK with the keyboard. With my 717 config, even taking off is hard. > > Another problem (I think) is the lack of lift.

Even finding other speeds like V1, Vr, V2 was hard. I found one report from a test pilot who flew the 717. As far as I remember, Vr was around 120kts with flaps 13. I don't know what Clmax actually means... Max. Lift Coefficient at ? (i dont know) My model takes off at about 190kts with flaps up, and about 170 or so with first notch of flaps (ie. one keypress, ?1/3rd of full?) I don't know how the flaps stages in the jsbsim config correlate to the fgfs keyboard control (which seems to increase/decrease by 0.333 of the full value 1.0).
