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.

Mag will only be here in a week :( no fun

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.

do you have checkt if it arm if you put the trimming on your controller total to the right, after connecting the lipo and switching on your controller?

I also have this problem since 2.0.39, but dont know why

Please see the Troubleshooting Guide. If you can't arm the motors, you're probably not in stabalization mode.

Hello,

I am in stabilize mode according to the mission planner.

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)

In the current version the IMU is not calibrated until the motors are armed. In the next version we do it both at startup and again at arming. It doesn't make any difference to flight, but waiting till arming confused some people so we'll revert.

 

You can sample 2.0.40 here. Please give Jason feedback in the comments there!
