Default HELICOMMAND 3A => Setup problems for TRex450

Hi,

I am flying TRex450SE v2 for about 10 months and recently decided to instal HELICOMMAND 3A.

I am practicing hovering with video camera on board and would like to get more stable conditions for video shooting.

My recent video here: http://www.rcuvideos.com/video/HeliSept1st2008-wmv

I have installed HELICOMMAND 3A, but I am struggling to set it right (swash-plate movement).

As I mentioned I have TRex450 with Futaba 7C (2.4GHz) transmitter.

What I did:
1) Set my Futaba 7C in H1 mode (each servo is acting from it's own stick as recommended according to HELICOMMAND manual);
2) I connected HELICOMMAND 3A according to manual;

My problem:
1) When I am checking swashplate movement I am not getting right bechaviour.
2) I re-connected servos in all possible ways and tried out inverting them in all possible combinations.
3) If I am looking at helicopter from the front , then swashplate bechaive as:
- Left servo as back one;
- Back servo as right one;
- Right servo as left one;
4) It looks like swashplate turned around 120 degree cntr-clockwise.
5) Any attempts to invert servos or re-arrang connections didn't help so far.

I'D LIKE SOMEONE WITH HELICOMMAND SETUP EXPERIENCE (for TRex type of heli) TO GIVE ME AN ADVICE REGARDING HELICOMMAND 3A SETUP on TRex450.

I am looking forward to receive some help.

Thank you,
Andrew.
