Pitch is reversed: where should I fix it?

Posted by Simone Chiaretta on December 17, 2012 at 12:33pm

Hi,

I was doing the first preliminary tests and was testing to see if everything looked ok.

Throttle, yaw, roll all works fine: if I move the stick the copter moves the way it should.

The one one that is reversed is pitch: with the front arm pointing forward, if I raise the stick, it pitches back (as in, coming toward me), while if I move the stick to the min, it pitches forward (like going away from me).

It looks like it's reversed, but it's weird because the radio configuration on the mission planner said it was ok.

Is there something wrong in the wiring up? I don't think so as apart from this little problem the copter looks like it's behaving correctly. Should I reverse the channel on the radio? or on the mission planner?

Or maybe it is correct that way and it's supposed to work the opposite way I think it should (stick up-raise front arm => pitch back, stick down-raise back arm => pitch forward)?

Thank you

Simone

if just reverse on transmitter, does the quad will move in right direction when auto pilot?

You can just reverse the pitch under radio config in Mission Planner. Whatever feels comfortable to you is correct.

Hello!

So, your copter was moving towards you in auto mode and you "reversed" the "pitch"? Actually I am having the same problems but I thought that I need to "reverse" the "roll". I have read that on different forums.

Please reply.

Thanks

I really couldn't live with the idea that I had to reverse the pitch channel to have it working correctly, so I searched around the site for something that could explain it (btw, the google search is much better than the internal search).

Basically it says that it's a bug.

I created an issue for that: http://code.google.com/p/arducopter/issues/detail?id=531

There were a couple of mission planner update a while back that had mysteriously reversed my pitch controls, the next update fixed their error.

Thanks for the tip on going to the advanced parameters. It got my pixhawk working clean. The exact advanced parameter is RC2_REV. It has to be switched from 1 to -1 to reverse the channel for pitch. That is if channel 2 is still set to pitch in the transmitter. cheers!

  Thankyou heaps for this. It fixed my issue aswell. My transmitter does not have reverse function when in multicopter mode so this was the fix i needed.

As Rechard told you, the best way to change it is by reversing the stick orientation in the transmitter settings. If you change your wiring, you are gonna have much worse problem with other axis and it will be totally unstable.

  I know its old post now, but Im having same issue. My Tunigy i10 does not have the reverse option in the transmitter itself when in multicopter mode, so only option is to try do it via the flight controller itself :S

I had this same problem. I kind of went into a mild panic and landed hard :-(

Interesting, answered this same question in another discussion to day already: http://diydrones.com/forum/topics/reversing-pitch?xg_source=activity

Mostly same as above though do it at your RC transmitter.

Hello all I have the same thing I want to reverse the pitch but can't. It is not longer an option in the mission planner?

I have a DX7 and thought I have reversed it on that but still does the same thing, so can someone let me know have to change the pitch in the mission planner?
