I did a flight model for the A-7 that works pretty darn good in all areas with one exception.
The least amount of alerion stick movement causes the turn co-ordinater needle to jump. IN THE WRONG DIRECTION :banghead: .
The panel I'm using is aliased from another plane so I know the gauge works correctly.
I'm stumped.

Mai oui! It is the guage that shows where you were supposed to go....

Just put an inop (make do) sticker on it and placard Day VMC Only.

That's a strange one, what is AFSD showing for slip angles etc? It must be sending out some wierd info or there is an unseen hitch in the FM somewhere, doing something that is getting picked up by the gauge.

Good luck, you are about as good with that stuff as anyone!

Same response at all speeds?

I checked the slip angles and compared them to other planes I swapped in,they are in line.

Same Jerry.
When I said the least amount of stick movement I mean LEAST. Just move it off of center and there she goes. Although the plane seems to turn just fine.

Still giving me fits. Going to put it to rest for now. Bring it back out when the A26 is done.

Look at the values for Weathervane Stability Factor, Roll Adverse Yaw, and Yaw Moment-Aileron. Compare to a plane that flies acceptable and adjust and see if this helps. However this can also be a weight distribution issue; if you have a lot of fuel in the wings, the nose may tend to drop suddenly when you begin to roll.
