Flying Wing problem

I'm building a Flying Wing with MultiWii (WMP + BMA020) but I'm having a problem with "stabilizing” the servo's.
As you can see on YouTube (GUI) http://www.youtube.com/watch?v=opNDTBT2 ... e=youtu.be
The GUI shows (after callibrating of course) that when I roll the wing, left and right are moving ok. :D
But when I stop rolling the left and right servo’s take a while to get in there neutral position, like it shows in the GUI. :(
This also happens on pitching the wing.
It takes seconds to get in neutral position as shown on video.
Also neutral position is not 1500.
It makes no difference to trim my TX, the problem stays........

Anyone got a solution on this?

My Config is:
Arduino pro mini 328 5V 16 mHz
WMP (Ebay clone, always been doing very well on my x-quad)
BMA020
MultiWii 2.0 > Flying Wing
Tried also MultiWiiConf_dev_20120522, but it makes no difference.
Also tried gyrosmoothing in the config with no luck.

argh same pb happened on my flying wing, but I can't remember what I've done....
idea : try to clear eeprom with arduino ide sketchbook exemple.
or maybee reverse a channel(elev) on radio and change servo direction in multiwii prog
