Short update here. Essentially, just waiting on a new GPS to arrive. The last GPS got struck by a blade when it rolled over during maiden 1.
I did accomplish getting telemetry and minmosd working. Because this Quanum Nova APM is not a standard unit, its mapping of the pinouts differs slightly and when I updated the firmware it rerouted then to these new pins, had to solder the TX and RX directly to the arduino side of the resistors. I also re-routed the 5V power to the minimOSD and 900MHz telemetry to be powered directly to the BEC rail. Used this rcgroups post as a guide.
