I have an SDX ccpm model and upright climbouts are straight. But when I go to inverted climbouts the SDX wants to roll to the right.

The SDX was setup properly using the swatchplate leveling tool. hovers collects no banking from side to side at a hover.

The SDX is setup with 135degree swatchplate per the manual

I have 3 BL 451 on cyclic controls the system is running on a Life 6.6volt battery

Im using the DX7 transmitter and 7100R reciever

Any suggestions, comments, concerns ?

what radio are you running?? you can use the swash software in the 8FG/12Z/12FG/14MZ to mix this out, the swash generally has to tilt a small amount to account for torque etc and are best tuned doing what you are doing. Even in a hover, the swash probably won't be sitting dead flat, but it's a good start. You can also do this by adjusting the limits in the JR radio as well.

Dr Ben wrote a good CCPM setup guide which runs through getting ride of most interactions at each end of the pitch scale as well, just goggle Dr Ben CCPM

Get that straight before we even start trimming the model.

BTW, the 140 mix works for 135.

Dr. Ben,

I looked in my DX7 and the choices I see are

1 servo norm,
2 servos 180 degrees,
3 servos 120 degrees, <<<presently set to this setting
3 servos 90 degrees,

I don't have a 140 degree setting on my DX7 or do I?

It seems to me that you may have some binding/interactions when going negative. Have you simulated the exact same stick movements on a workbench and observed the swash and all the linkage rods movement?

The DX7 does not support 135/140 eCCPM with the native software. That's why I posted the link for you to follow if you choose to use 135 on your SDX. Otherwise, change it over to 120.
