My ini A350 sets take-off flaps after ground roll-out. And also sets the flaps during approach. The flaps all work very slowly. My engines have started. I set the flaps from 0 to 1+F which took me 1 minute. Also setting the flaps from 4 to 0 took me 1 minute 30 seconds. The ini's equivalent, the A320NEO, has the same problem of very slow flap response time!
