Hello,
I tried to make a new aircraft model in Yasim, but in the middle of work, I noticed a weird behavior of yawing in full rudder deflection - the yaw movement stops, after a particular angle similarly as in case the nose of aircraft will be towed by a rope.
To eliminate possible trouble with my model I made test flights with several Yasim aircraft, but all behave similarly. The trouble is clearly noticeable even in the case of the new version (5.0) of ASK21 glider in the Yasim model variant, but it is not present in the JSBsim model variant. The problem is clearly indicated by the Turn indicator instrument.
The expected behavior is the ability to make a full circle rudder-only turn (uncoordinated obviously), instead of this, the aircraft stops turning at certain heading.
I am not the first one noticed this, there are multiple posts mentioning similar troubles:
