I found that APM is not waiting for IMU calibration causing the AH and GPS to be all over the place, I fixed my version with OSD support, Randy should really correct this as he may have plans for no calibration operation,
If you wait 15 minutes it will settle down and lock in IMU. Compass swings around until IMU lock,
GPS location jumps around earth until X sats are found and (x=4 to 6 sats used for nav)
I am running 2.0.39 I do no know if this problem is related the new firm wear or not .I am unable to arm the ESC by moving the yaw stick to the right. I can arm the ESC manually from the Mission Planner by changing the ESC value from 0 to 1. this only works once after power down the I have to repeat the process ever time, I want to spin up the motors . I am using Turnigy AE 25 amp ESC any Ideas. Other thing I noticed is that camera tilt servo moves around a lot at start up. I do have my sonar attached to the bottom of the camera mount . the other issue I had was if no GPS lock the horizon would spin any help would be grate.
ok so I took ome other advice and flew with a small 3 cell instead of my big 4 cell... and the problem is gone!? I have no idea why it does not like 4 cell?
ok thanks for the input. I am flying in stab. mode, (conflicting views about whether a mag in needed...) GPS is connected correctly. Will try simple mode.
Got up and running with the latest firmware. BUT... when I plug the GPS in I get a yaw glitch the spins the copter around 180 degree while in forward flight... Is this similar to the yaw issue being discussed?
I am still waiting to get a MAG, could this cause this issue?

no I do not have checkt. What is that how can I get it?

Mag will only be here in a week :( no fun
Hi I am New to the ARDU :)

i hope can setting servo gimbal on ROLL from AMP.
revese and travel adjust servo not work, i just change from arduino :(
I too had the rolling horizon when connected with USB.
I don't have Xbee on the quad, that is on the plank at the moment.
Was VERY nervous on the first flight of the quad :-)
Just tested v39 available from the trunk.
Flight seems quite stable (little windy at the moment).
Sonar does not work. Getting 137 as value.
Also leveling the quad with MP isen't possible. MP askes for the version 37.
Keep up the good work.
Thanks
Where are you finding 2.0.39?
All I see here http://code.google.com/p/arducopter/downloads/list is .38
(pf course, by the time I write this, some clever person will have updated the download page and I'll look like an idiot. Again. :) )
