I've ordered a NAZA and have just realized my JR XP8103 doesn't have a three way switch.  It does have three channels with knobs.  Each channel has three wires on the pots.  Can one of these be used in lieu of a switch or can one be replaced with a switch.  Normal and ATTI is all I need.  Would using the Heading Hold swich serve the same fuction?  Ideas, anyone?

As long as your not using GPS you only need two flight modes.

What is the Heading Hold switch?
And you can replace the switch

I could give you a great deal on a JR 10X or JR xp9303.

I programmed my DX8 so the knob allows me to switch between GPS/ATTI/Manual or GPS/ATTI/Failsafe using the 3 position switch. I did this by setting up one of the mix screens.

If you adjust the opposite end point then the knob will allow you to switch from GPS/ATTI/Manual & Failsafe/ATTI/Manual.

You can change any knob pot to a  three way switch . There are a number of threads you can find on this.
