Flaps wheel too slow? (video)

[VO101_Tom]

Hello guys

I was flying a lot yesterday with Bf-109. I noticed a thing, which is not bug, but seems to me wrong: flaps wheel moving velocity. I am surprised, for what so slow? As if would be heavy to move. Shows if you look at this video, that easy to handle (and much faster). The number of the turns does not seem a lot (i don't know exactly how much are needed). The moving velocity could be faster however. Opinions? (from 5:30):
