Did you have a gimbal mounted camera attached?
I haven't done what you have so I have no experience in this but I would personally do the following:
1 - full visual inspection of the entire RPA & the batteries, looking for any obvious damage to the air frame or parts. Pay attention to the arms for cracks as well as loose screws, any cables that are visible are not damaged
2 - turn the motors and note any resistance to movement (like sand in the motors). If there isn’t you'll need to take the prop mounting plates off and clean it out
3 - get rid of the White props, you have spares so just write them off
4 - power up without the props on and systems check, re-calibrate IMU, Compass, Gimbal (if required), check GPS connections, take note of the battery levels, any cell imbalances (if the batteries are damaged - you'll need to dispose of them safely)
5 - Cycle the landing gear (without the props on) and check movement
6 – In a safe space (without the potential of other people walking into the area) Props on and power up, then command motors on, leave running on the ground. You may want to anchor the landing gear down and do a throttle up power test. Take note of any sounds or vibrations that aren't "normal"
7 - If all is OK, do a low hover test, then slowly expanding the envelope to include turns and forward/backward flight
After that you’re going to have to take the plunge and start operating it as normal however I caution in the first few flights to ensure you are in a safe flying area (I know we always have to keep our distance from people but it’s even more important in this case – including your safety).
