I am having trouble with my throttle, both ch throttle quadrant and my keyboard. After I installed Ground Environment X my throttle started to function improperly. I would set the throttle on my ch throttle quadrant to full and the engine would momentary go to full before returning to idle. If I press and hold the F4 button my engine with go to and maintain full throttle, but as soon as I let go of the button it returns to idle. I did not have this problem before I installed Ground Environment X. Has anyone had a problem similar to this? I would like to be able to fly without holding down the F4 button.

Hi there,Have you checked the control axis assignments in FSX to make sure there aren't any unwanted assignments? Sometimes that happens for no apparent reason.

Thank you very much. I fixed my problem. There were conflicting assignments.
