Unable to calibrate with MC-16

[meatbomber]

Hi !

just found FMS and it's looking great !

I'm using a Graupner MC-16 on Win XP, with a USB adapter to Serial (on a laptop, no com ports anymore)
with the Cable i have, there is no problem flying in Easyfly, but in FMS i can't calibrate.

The bars move when i move the sticks but apparantly with no correlation to stick movement.

Any ideas ?
