Hi, I have a problem with my V-tail model analysis on VSPAERO.
When I select a "rudder" deflection on VSPAERO the control surface moves but when I select a "elevator" deflection the control surface doesn't move!
I checked the grouping and it seems correct, can somebody help me solve this problem?
Thank you

Lorenzo

Looks like a bug.

If I delete your rudder control grouping, the elevator grouping works.  I'll see if I can work it out, but hopefully you can work around it for now.

Thank you for the response, how can I work around it? Should I add a second control surface to move the elevator or is there something I can do on the settings?

Just save two files -- one with the elevator, the other with the rudder.  Run things twice, figure it out.
