Rusty Dog

All my other planes (Fenix/PMDG/iniBuilds) are fine and work perfectly the steering and throttle. The Tristar is giving me grief. I need around 50-60% throttle to get the plane moving. When its gets doing and picks up speed over 20knots, I have to back off the throttle a tiny bit and it's enough to decelerate the plane to an eventual stop. It's like the brakes are stuck on (they are not of course). Then comes the steering. I don't really have any. I am using a Virpil joystick with twist feature for the rudder (I don't have pedals). Again it's fine for every other aircraft I own. On the Tristar, when I try to turn a corner when taxiing, it will start to turn then just turnes back and goes straight on. Whe nose wheel is turning too much too fast. But even when I try to be gentle with it, it will begin to steer into corner then the plane loses speed and comes to a stop again. It was impossible and I had to use a 3rd part tool to turn the aircraft on it's axis instead (MDAdjuster).
