I know this is my second post in 2hours, but anyways.....

I just setup my dx6 to my t-rex 450se v2. Checked the controls, aileron works fine as well as rudder, but elevator and collective are switched!

When i move the cyclic stick forwards, the whole swashplate moves up together, when i move the collective/throttle up, the swashplate tilts forwards (motor was unplugged)

Nothin in the manual on channel assignment.

In a few words: my forward/backwards cyclic has switched places with my collective.

How can i fix this!

and thanks in advance

To add to that, i did try switching around elevator and pitch servos.

If I remember right you have to go into the swash mix and reverse polarity on some of your inputs...

Another victim of the CHANNEL reversing verses FUNCTION reversing (lack of) understanding.

I'm going to assume you have your servos back in original config. ... ie Elevator servo plugged into elevator channel
and aileron and pitch servos plugged into aileron and pitch channels.

(1)First ... you have to get the servos moving correctly relative to each other ... fixed by reversing the CHANNELs
(2) Second ... you have to get the FUNCTION working correctly relative to stick movement ... fixed by reversing polarities in the SWASH (FUNCTION) menu.

OK let's deal with collective pitch movement (fixing this will more than likely fix the cyclic issue too)

ALL servos need to lift or lower the swash TOGETHER ... ie move correctly relative to each other. In your case " ... the swashplate tilts forwards ...".
These means one of your servos is not playing along with the other two. Since the Ail and Pitch are playing together (your not getting sideways tilt), the elevator
servo is the odd servo.
In this case, reversing the elevator channel would make the elevator servo move correctly relative to the other two. This may not produce the correct swash to
stick movement ... but that's step (2).

(2) Step two is to get the servo FUNCTION movement correct relative to stick movement. So IF (verify this on your heli) you push the collective stick forward and
you get negative pitch swash FUNCTION ... then the pitch FUNCTION (not CHANNEL) needs reversed.
As evan-RCU stated, this is done in the SWASH function mixing menu. In this menu, reversing the polarity of the pitch setting will reverse the pitch FUNCTION. IOW ... if you currently have
a pitch setting of 50% and the stick to swash movement is backwards ... change the 50% setting to -50% and the function will reverse.

BTW, by your description ... this should fix the "collective" response when cyclic stick is induced. Just make sure you perform (2) on all of your functions ... make sure
your stick to function movement is correct.

" ... Nothin in the manual on channel assignment. ..."
Try page 89 for the swash mixing functions
Try page 90 for where the servos plug into the RX.

Thanks! It worked!
