Bad AHRS -- ArduRover 3.4.2

Hello, I have been trying to set a traxxas slash with ardupilot 3.4.2 and I keep having a bad AHRS message. I have been checking all kind of posts and nothing seems to work. Given this message, I can’t arm the vehicle and if I disable the ARMING_CHECK parameter I can arm it but then it starts moving like crazy. In fact, last time I tested it, it started moving backwards.

Any help will be highly appreciate. Thanks in advance :slight_smile:

Hi Leonard,

I think this “Bad AHRS” is just that it doesn’t have a good position estimate yet. I plane to get rid of this message in Rover-3.5 but it’s not quite done yet. I think you’ll find that once it gets a good GPS signal the messages goes away.
