How to configure PIxhawk with Graupner mx-20 for diff. flight modes

Hi again,

now I have problem with the channels:

The RC is in airplane mode, and stick mode 1.

The controls are:

- the left side of the RC are the throttle and yall;

- the right side are the roll and pitch.

The problem are the roll and pitch - THE CHANNELS ARE REVERSED.

- When I put forward i go to right, when i pull back, go to left. :(

What can I do?

  RTFM, then reverse the channels. :)
  
  You should try to open the manual, the radio offers many nice features you'll never discover unless you spend some time with it.

    Hi,
    
    I am writing because I couldn't find them.
    
    There is a section in the manual:
    
    -Joystick setting:
    
    Detail program description - Joystick setting.
    
    And I am not sure, after I read the manual can I use it for reverse the channels?
    
    -Another option that i see is the Wing mixers;
    
    I will test today, if any other idea you have, you could write.
    
    Thanks, have a good day.

      Under "servo adjustment" - change the arrow direction to invert. :)

        Hi,
        
        This is only if the channel is reverse. :)
        
        Maybe there is some misunderstanding:
        
        - when it has to be pitch it act like roll. This was the problem.
        
        And yesterday I made it, it is easy to change them from "Advance list parameters". You can assign the channels manually(I forgot exactly which parameters I changed), but it's very easy, there is description in the right for this.
        
        To reverse one channel you can set again manually at:
        
        chNUMBER_REV -1
        
        My new settings for PID are:
        
        "P" for roll and pitch are 0,30, it's react very fast.
        
        "D" and "I" are 0.0000
        
        So now it works perfect.
        
        But now I have another problem:
        - at my transmitter, I am almost at the middle of the sticks and the copter react like I am at the end.
        
        So from Pixhawk is there a option to make it work with all way of the sticks?

        Maybe is normal in stabilize mode to be so aggressive.

sorry : "failsafe"

When the receiver loses connection.
- Andre K. > Nayden April 30, 2014 at 4:55am
  
  that's easy if you use with PWM , and even easier with PPM connection - easily set up in mission planner or APM planner.
  
  I suggest you check out documentation on ardupilot.com

    Thank you,
    
    All is good now, but I have problems with config of PID..maybe.

That description seems to use 3 switches, to get 6 modes. - it also seems to use 3 of your precious 12channels. a mess. :)

My way, is to mix CTRL9 + SW8 directly in MX-20 , then send output in one channel.
If you understand my notes /(I expect you to do) :) - and do it right, there's no adjusting or tuning - all 6 modes will be hit perfectly within PWM limits.

Input5 Ctrl9 (Ct9)
Input10 Sw8 (8)

Servo adjustment
S5 travel 65% 59%
S10 travel 70% 85%

Free Mixers
fr10->to5
symmetric +20% +20%

ch5= main mixed output

Enjoy :)
