I have several Sentinels that were shipped with taoglas GPS/mag unit, ghost atto receiver, and orqa controllers with the ghost atto uberlite-24 transmitters.  I also have some older sentinels that shipped with a different GPS/mag unit and the spektrum receiver/bind board.

Is there a way I could purchase the GPS/mag units, ghost atto receiver and transmitter/controller and cable assembly to the J19 connector that were used for the last iteration of the Sentinels?  I don't even really care about the GPS/mag but I noticed on our newer quads there are wires from the ghost atto receiver board and the gps unit spliced together going into pin 1 of the J19 so I can't just hot swap the spektrum receiver with the ghost atto one.

Wanted to check in again.  Any advice on swapping spektrum RC for ghost atto on voxl2?
