roll and pitch reversed only @headfree with Spektrum DX7s

[whitesharkwf]

Hello,

I have a problem with my Multiwii Pro using my TX "spectrum DX7s".

When I switch to "headfree" my pitch and roll inputs are reversed.

So when i push my pitch up, the copter is coming towards me, when i pull it down it moves away from me.
Roll to left: copter to the right.
Roll to right: copter to the left.

In acro, horizon, angle and any other possible flight mode the direction is correct.

How can i reverse roll & pitch only for headfree?

The TX input in WinGUI shows correct.
Roll left: 1000 Roll right 2000
Pitch down: 1000 Pitch up: 2000
all@about 126% way caused by spektrum to get the full way between 1000 and 2000

Thanks in advance and sorry for my bad English!
