High magnetic_field

[Allister (Allister Schreiber)]

There’s a lot of current related issues here. You may have to move some of the power wires away from the compass/GPS module and work on shielding. It’s common with the cube to suggest using the external compass over the internal, but the external on here looks like it’s getting much more interference.

You might consider running MagFit on this quad to improve the COMPASS_MOT values, but only after you’ve tried to fix some of the wiring issues.

Here’s a good post that might give you some clues:

Grounding issues

Good find Mark! ESC grounding issues are made up 3 forms of ESC signalling/coupling problems, resistive, capacitive and inductive. All three should be considered when building an aircraft. Inductive: This is the tendency for sudden changes in current to cause large voltage spikes in your system. Inductance in your power system is primarily caused by the size of the loop formed by the positive and negative leads between the esc and battery. So the longer the cables to the ESC the higher the in…
