Compass purpose?

Hi there

I'm sorry for such a basic question but I just want to make sure I'm not missing anything as I'm a total beginner at this.

I need my RC plane to send back GPS data to overlay onto a map. So I've bought an ArduPilot 2.6 and a GPS unit, without a compass. I'm assuming the compass's only purpose is for people who want the plane to fly to pre-determined GPS waypoints. I'll always be flying my plane in line-of-sight so I don't want it to fly by itself so am I right in thinking I do not need a compass?

Any information or help would be much appreciated.

Many thanks

Clive

  • no, you do not need it.

    On a plane, it's used for better xtracking in sidewind, not very imortant, and you can fly just fine without it.

    For a multirotor, magnetometer is an essential component.
