Control problems on take off

[gordie3640]

I have downloaded two Gulfstream 100s from the library. They are different in appearance but I can't get them both to open. In any case, they both have the same characteristic. On full power takeoff they vere wildly to the right. They behave well during taxi to takeoff.

Check that both throttles are moving together and not just one of them when you apply the throttle, if only one moves press e+1&2 in quick sucession check that both throttles move as one unless you are using twin throttle levers check calibration.

Also, use external view to check that rudder is straight and both engines are running?

I had a problem where as soon as you throttle up the rudder would kick hard left and you could not get it to straighten out. The problem turned out to be a calibration problem and I had to turn down the sensitivity on the rudder a little bit. Some two engine aircraft like the default Beach Baron have a prop sync switch on the panel though if it really works or not I am not 100% sure.
The problem in most cases is the throttles are not locked and only one engine throttles up which would make the aircraft turn in the direction of the faster turning propeller.
Make sure you monitor your engine gauges and you can spot the problem quickly. or open the throttle window and move your throttle forward and if they do not move together there is your problem. You can do this even when the engines are not running that way your plane does not go careening down the taxiway
