How are you controlling your flaps? How have you tried to set up the elevator compensation?
I just use a flap to elevator mixer and it works fine.

I have attached a couple of screen prints showing  a Flap to Elevator mix that I have just created on the "sand pit" model I use for experiments.
One shows the basic mixer screen where I have set up a 50% master input value.
The other shows the 3 point mixer curve I have used so the mix only moves the elevator one way from neutral when I operate the flap control.
It works fine as elevator compensation when flaps are deployed, and you can adjust both the master value and the curve to get the correct amount of compensation to suit your needs. Does this help at all?

Just another thought - I see you mention your problem being with "take off flap", so perhaps you could just make a "take off" flight mode and use the flight mode elevator trim to get what you want. If set up as separate (S) each flight mode has its own trim setting.

With this trasnsmitter this is certainly the quickest and simplest way to do things. If you set up 3 flight modes, take off, cruise and landing, it is possible to make life with even the most complex model types very simple. Once you have this on a three position switch (with voice announcements of course - sounds on events), you can go into curves. Here you can select a constant curve  for each flight mode, and then simply adjust the point to the position you want to set them in. Then in flight trim the model in take off mode, and flick the switch into "cruise" the flaps (and gear if fitted) will go up and you now retrim again, Same procedure for landing mode, and the model is trimmed. If you use autotrim, the whole thing is a breeze.
Whilst you are at it, you can turn off brakes and steering in the cruise mode.
