I'm using my unused DSLR bags. The shoulder bag is from Canon . I believe they're available at Best Buy for about 50 buck$. Keep the
Mavic 2, extra batt, small G-15 camera and an infrared thermometer gun in it. Side pockets holds the charger, antennas and what ever else. The RC is in a small pouch. The narrow Domeke bag holds a prop set.
The Mavic is in a lens case that came with my Canon 100-400mm zoom lens. Although not a tight fit the inside of the lens case is loose fabric that props catch on so they're removed before repacking now. B&H sells this case for about 50$ bucks. I also have rubber motor covers in place.
Sears (if you still have one) still has a huge variety of tool bags at a full price range.
After flying, the drone, batts and RC go the floor of car under the AC vent until I get home. Then this is repacked.
Been taking pictures since the 70's. Shoulder bags are what I've become accustomed to and I think reshaped my body to accommodate .
