Well, I am still flying successfully. My quad has far exceeded my expectations. Some upgrades I've done are:
1. Added Optical Flow Sensor (Not activated in 3.2 APM firmware unfortunately.)
2. Added Left hand Circular polarization antennas for FPV
3. More batteries for extended flight times.
The weather is finally warming up, and I've been out quite a bit! Below are some of my logs:

Thanks everyone for all your good advice and for following along!
