Pitch stick control is reversed

Hi all! I've assembled my ArduCopter recently and started testing it. Firstly I checked stabilize mode holding copter in my hands, it works fine. Then I decided to test control from the radio. I was a little confused when noticed that if I move pitch stick back front motors commands decreases, rear motors commands increaes; if I move pitch stick forward, front motors commands increases, rear motors commands decreaes. But that's should be vice versa!

My ArduCopter's frame configuration is "X". Roll and Yaw work correct.
I looked through the wiki troubleshooting and it's said there that frame configuration might be set wrong (I set X as my quad really is; but I tested + too, the same result), motors hooked up in right order and props directions are right too.

What else could be wrong here? 
Thanks in advance for your replies.

  • Yes, thank you very much, it helped! Jason, values were about 4500, -4500. I just reversed pitch channel on my transmitter and all became correct.

    I had idea to try to do it, but decided to ask first. Thanks again.

  • Could it be that you just need to reverse the Pitch channel in your Tx?
  • Developer

    Run the CLI test for radio.

    Move you pitch and roll stick to lower right corner. What's the value? Should be  4500, 4500 or something very close.
