Acceleration in IDLE thrust is too slow. In the real aircraft you release the brakes, maintain the engines in idle and the plane will easily go up to 30kt all the way at MTOW.
On a typical 3km taxi distance you will need to brake it back down to 10kt at least two times without ever using any thrust above idle.
The simulated A330 won’t even get close to 30kt a single time in that taxi distance.
Unlike the PC-12 which can almost take off on zero throttle
