How to use Ext. Mag. on APM2.5?

I'm going to put an APM2.5 on an Trad Heli, and I need to use an external mag so that I can have it on the tail away from the main motor.  How do you do this?  I see the solder jumper, but I haven't seen any documentation on the use of this jumper.  Do you bridge it to enable the Mag, or disable it?

  • Ok, so Jeff Smith figured it out.  There is a solder jumper pad which is pointed to in the APM2.5 announcement:

    Between those two pads, there is actually a tiny trace linking them.  You have to cut this trace.  Now the onboard mag is disabled.  If you ever want to re-enable it, simply bridge the solder jumper pads to reconnect the circuit.

    Simple.
