Erractic elevator movements

[rsquared]

With a normal functioning CH yoke and controls and without any known changes that I can identify, I have lost effective control of my elevator function for all a/c. Movements are extremely jerky, large scale movements up and down when hand flying. When AP is engaged, I am able to maintain level flight but when disengaged, maintaining control is almost impossible. I tried rescanning the elevator axis but there appears to be no intermediate movements between the two values of -16384 and 16384. I have attached my extracts from my ini file and a flight log to aid in problem identification.

All other axes on my CH rudder and throttle quadrant seem to be functionng normally

Sounds very much like you have it assigned in more than one place. Either that or you have two axes assigned to the elevator (perhaps one not even connected) and this is causing cross-interference. Check both FS and FSUIPC assignments.

This line in your INI file shows you have left the Elevator calibration completely to default values, as these are FSUIPC defaults:

Elevator=-16380,-512,512,16380

Why not try calibrating, as documented, and see if that helps?

You only showed me the JoystickCalibration section of your INI, so does that mean you aren't even assigning any axes in FSUIPC? (They would be in the Axes section). If not then all of your problems will be found somewhere in the FS assignments.

Thanks, your comment about two axes assigned triggered my memory. I had briefly plugged in a Combat Stick and although I thought I had checked to ensure tha the elevator axes did not get assigned in FS, I must have missed it. At any rate, I dumped the old INI file and did fresh axes assignments, calibrated and all is well again.

On to my next question, I have used the method you describe for using an axis assigment to control the landing gear (page 48) to activate my my flap settings. But, having read the guide several times on how to calibrate flaps, ( p.54) I can't seem to duplicate what you have done there. Specifically, I can't get the spin control to increase in value when I click on it - hence my inability to set specific detente settings. Moving the flap lever does not cause the numerical values to increase or decrease so it seems that I must have missed something along the way.....

Thanks

Sorry, I don't understand that. There's no similarity between selecting flap positions and operating the Gear, which is merely up or down. Furthermore, the Gear was a case where there's no axis facility in FS -- the example was how to apply a hardware axis to other switching control events. Both FS and FSUIPC support a flap axis and you can assign to it directly.

But, having read the guide several times on how to calibrate flaps, ( p.54) I can't seem to duplicate what you have done there.

I don't think you are assigning your flaps lever to the flaps axis, that's why. I've no idea what you are assigning to, but only axes are "calibrated". You see no calibration for Gear operation, do you?

Do it in the same way as assigning any axis. You are confusing on/off or up/down toggling controls with axes.
