Ok, Im back with report - yeees! It works as it should, I use this Rot X function (set up as Zero here).
In taxi and take off I see flaps like on 30-45 deg. After reach 155 kts they are closed

.
Sometimes it is not worth giving up but fighting to the end, then the satisfaction is greater

. TY John!
I hope this "investigation" helps to the others too.
btw. now I will try to Cessan Bird dog, so I need something like 80 kts for flap. I must edit now this entry in modeldef = 155 <, for 80 before saving the model (so do it each time if I change a kind of model, Am I right?)
