When I hit Y to go into slew mode, my plane increases its altitude very, very fast. I have to press F2 quickly to stop it and F1 to come down again. Is there a way to avoid this altitude increase, e.g. by making an entry or change in the config-file? Grateful for help.Roland

Your controller axis are not centered properly.My advise:Go into menu Options-Controls-Assignments, Slew Axis, and delete all the Slew assignments for all Axis.So your aircraft will never move again when you press Y.And instead, use the (numpad) keyboard keys for slewing around.Rob

Thanks Rob,There was actually a slew-axis activated as Altitude axis in my Assignments file. I was not aware of that. After inactivating it, but keeping the fore/back axis active, everything was OK.Thank you again for your kind help.Roland
