Upgrade to 2.0.39 (or latest). Yaw has been through several improvements.
Now it work much better!

I could have sworn I responded to this thread but geez, gone. Maybe i did not hit 'add reply'...

 

Anyway, first update to AC2 2.0.39 (or whatever the latest is now) and update the mission planner.

 

This will not fix this issue but you will be asked to do so. 2.0.39 still has the 'springy' yaw.

 

I played with Yaw PID's a bit a few weeks ago and asked how to possibly resolve this but never really got anywhere. I will be trying to work on this again myself in the next few days.

Is there anyway to lock yaw into one position? To start off with I prefer not to have it while learning to fly

No easy way that I know of.  I'm sure it could be done, but you'd have to figure out the code yourself.

Have you seen "simple" mode?  Might help you.

what does simple mode actually do? Im also curious about how stabilization works if you fly indoors with no GPS. Does the stabilization need GPS or is it relying on the gyros etc?

Simple mode basically makes the yaw orientation of the copter irrelevant.  Basically, you take the quad, and stand behind it with the nose facing away from you.  Arm the motors.  Now whenever you push "up" on the stick, it moves forward (away from you), no matter what the orientation is.  Back brings it towards you.  Left is left, right is right.  No matter what direction it's facing.  It moves orthogonal to the original setup.

Stabilization will not stay in one place, even outside with GPS.  All it does is stay level.  But it can drift around.  So it does work indoors, but you have to prevent it hitting walls, etc.

• Ok thanks for the explanation. So it will make it easier to learn to fly not having a yaw I would suspect? Or do you recommend a better setting?

That setting might help you learn to fly, assuming it works well.  Although it could also be a crutch that prevents you learning to fly properly.  I think a lot of it comes down to your attitude towards it. I would attempt to try to keep nose pointed out, and try to maintain orientation.  But if you do lose it, it won't go flying into a wall because you put the wrong input.

 

I've never used it myself. You do need a magnetometer to make it work.
