Questions from a new user

We had to abandon our DJI equipment including a 6 month old M300 with P1. Our new system will be a Alta X with a Sony A6000 camera. We’ll be using a Gremsy T3V3 Gimbal. As I understand it, that is full-range omnidirectional. The Herelink RC uses QGroundControl. I was hoping that it would have something similar to DJI’s Smart Oblique. It’s somewhat disappointing to see that there doesn’t seem to be an option for oblique angles at all. does this system only fly Nadir?

Also, the system is being ordered today. Am I making a mistake by sticking with the A6000? We’re only using it for SFM mapping. Most processing reduces resolution below that anyway. Any advice would be appreciated.
