2.0.39 Available

tried 2.0.39b this evening,
stablize mode is very smooth and nice, altitude works great;
loiter starts ok, but then very aggressive manoeuvres, constant overshooting of the loiter point, becoming more and more aggressive until I have to switch loiter off to prevent a crash.

I changed now the PID values for loiter and will try again tomorrow ...

Made a few flights with 2.039b today. Stabilize works fine, however I found some issues with descending.

When vertical speed is more then - 0.7-1m/s (negative, going down), copter starts to oscillate (and as faster as more) and an only way to prevent it is to increase throttle and stop descending. It's a bit inconvenient (and sometimes really scary) and it becomes impossible to decrease altitude fast. Any ideas how to solve it? I guess, some PID tweaking required...

Weird behaviour with 2.0.38.

Stablise mode OK.

Altitude hold OK.

Loiter, ok for a few seconds then the copter starts banking left and right, bigger and bigger then then I switch to stablise.

i want to order an arducopter but i don t want to buy gps and mag for the moment

i would like to know if i can fly withtout gps and mag(only with baro,acc and gyro)

others little question

if i want to buy sonar,can i fly with it without gps and mag?

thanks for you reply and sorry if my answer had already asking

I've loaded 2.039betta today and made a few flights. It was perfect! The most stable version I've seen. No more problems with yaw at all. I checked ALT_HOLD and LOITER modes. ALT_HOLD works pretty good, but LOITER is not very stable, copter is ocsillating about 2-3 meters, maybe it's because of the wind, however it wasn't too strong. Anyway, going to make one more test tomorrow.
I have a couple of questions. There is a figure of quadcopter on the map in Mission Planner with one leg marked. I fly in "X" mode. Front-Right leg is marked or marked leg shows the direction of the copter?
When will 2.039 code be able for download through APM repository? I see only 2.038 there.

So what is new in 2.0.40 ? and does it need 2560.

Chris,

Could you please relink the 2.0.40
It doesn't seem to work here.

Thx

Just reloaded 39 trhough MP again.

Using APM board 2560 and the MaxSONAR MB 1200.

Still no sonar.

Stays at 137m

I loaded the latest (.39 ?) into my quad, and it was quite stable in position/altitude hold on Saturday.

Too busy with the plank UAV to spend much time on the quad though.

The only weird part was that the HUD rolled around while the usb was connected.

I have sonar, mag and gps connected, on the old 1280 board.

Hope this helps.

Any news on the sonar alt problem that some of us are having?
