Congratulations!!!!! So you are not using the posted 2.2.3 code? Hopefully Jordi will update the "official" code with this one. You've inspired me to get my plane back up in the air and start playing with Ardupilot again.
Thanks!

Congrats! It's great to hear hear more and more people getting their Ardupilots in the air.
I *think* you can fix the oscillations by editing the easystar.h file and lowering the heading gains.
Fine #define head_P .7 and reduce it to something like .5
I'm not 100% sure though so it might be best to wait for Jordi's input.

Hi Peter!!!

Did you change the code only to customize your flight or the code has some problems?!

Regards.

Only thing I changed is Waypoint print enabled, from what Jordi uploaded.

And the GPS Type, he uses UBLOX - I use SIRF...So his gains maybe higher then mine, funny thing seeing the easystar managing a turn to the right at almost 90 degrees and then getting out all on it own :)

Is climb rate not used in the ground station ?
I see it defined to 0 but never changed anywhere in program.

Also, I see a place to calibrate the input voltage, but the battery voltage on ground station doesn't use this calibration.
On my system I use this line of code to make the ground station print out the correct voltage. (in system tab)

Serial.print(Battery_Voltage((analogRead(5)))*.9478);

Good for you Peter....
I haven't had a good flight yet but I did have one where under way-point test the Easy Star was oscillating wing tips ( dipping each wing back and forth )....Like it couldn'nt make up it's mind which way to go go ....Is that what you mean by swerving left and right .... I was afraid to let it got to far as my eye sight at 73 is not the best so I switched back to manual ... Would you recommend I try Jordi's " I_ CAN_FLY Code "
Tnx and keep trying ....You may help us all .....

Take Care De VO1ET Jerry

My swerving was more controlled, tight left and right turns over a medium radius. Totally controlled by autopilot, but the bank angle was almost a full 90 degrees. So to me that was not ideal for the plane, safety etc..So I dialed it down, no more swerving. Hunts right for the waypoint everytime. Now once i dial in the gain and radius ill be finished. Doing a flight tomorrow, 1.3 mile flight with 4 waypoints. I think the longer the flight the better it works, if your waypoints are too close a lot of times it can't hit them with success. Like my flight this afternoon, once it made waypoint 1 it started towards 2 but with only a small space between it constantly kept going back to 2.

I am 95% finished - only small tweaks go forward. I also fly the attopilot, but thats pretty much plug and play. So this is so much more fun learning all this stuff rather then plug and play. I will be purchasing a 3550 UNAV unit next month, they are very close to my house. I am also using the UAV Devboard with AileronAssist and RTH for aerial video FPV and Aerial Photography. Works like a charm, thanks to Bill P. And now with the telemetry the UFO-MAN is working on - I see that platform growing massively over the next 6 months...
