2.0.17

I loaded 2.0.17 with the APM Planner and experienced something I've not seen before.  I flew for about 5 or 6 minutes, deliberately not touching the rudder to see if the quad would maintain its heading, which it did.  I then gave it a tiny amount of right rudder and it started to slowly rotate and it kept rotating for a couple of minutes.  I could not then make it do the same thing with left rudder.

 

I'm running stock everything, stock settings, with sonar and magnetometer.

Here is the KML File for JUST the time the mode was in loiter.

(Could not get the log reader to work, so wrote my own log -> kml converter)

I've also attached the log file.

Just starting to lear where things are in this system.

That looks like something was broken. I'll look at the code more tonight.

I see this repeated over and over during Loiter. Not correct.

Jason and others,

I just conducted my first flight with a newly built arducopter using 2.0.17

It was my very first quad flying experience and a first flight for the airframe - gotta start somewhere

I just flew around the one area in 'stabilize' mode.

Apart from popping a couple of plastic screws on the landing gear when landing firmly on soft ground all went reasonably well

When I left the controls alone the aircraft flew fairly well apart from some uncommanded slow yaw rotation at one point.

It seems you've updated to 2.0.18 while I've been out flying  - something to try later

Here is a Youtube Video of the flight taken by herself with a mobile phone.

A big thank you to Jason and everyone else for producing a product that can work so well first time

regards

Andrew

This was mentioned a few times here http://diydrones.com/forum/topics/yaw-control-with-compass

I have this issue and it repeats each time I fly, I am stuck with ardupirates until it's sorted :(

I submitted a bug and it was closed, someone opened a new bug (152) and it was closed yesterday....grrrrr
