Trim control not adjustable

[Guest christa]

Hi,I have both A320Pro and A330/340 in the boxe version and aftermany years of operation without problems suddenly beforeshort time the following problem started in both versions- when either aircraft is called the trim control all on its own goes either to fuull up or down and thereafter cannot be adjusted, result is that the A/C cannot take off.Sometimes the trim is set to zero then all preflight settingsare set normally including trim to -3.0up,but when I accelerate to flex then the trim automaticallysets to 8.0down and the plane cannot take off.FS9/XP/registered Fsuipc 3.74/ Any ideas of what is going wrong?

>before takeoff trim to -1.8UP and go to this is the problem I face, that the trim goes automatically to max down(-8.0) and is not possible to be adjusted. This happened suddenly without any changes. >C:Program FilesMicrosoft GamesFlight Simulator>9AircraftPSSAB-Propanel go to window 08 and change the>size mm to 2,2 This already have been done time ago with the 'mouse flicker' patch.Thanks anyway for your replyTakis
