The Q500 4K is an older but solid camera drone. The issues I see most:
- Won’t bind to the ST10+: confirm matching firmware, fresh controller batteries, and run the bind with the drone and camera close together.
- CGO3 camera issues: no video or gimbal errors usually trace to ribbon cables or the gimbal board. See CGO3+ three beeps guide, much applies to the CGO3.
- Short flight times: aging batteries. See battery care guide.
- GPS slow to lock: same advice as the Typhoon H, give it open sky and time. See GPS acquiring guide.
I stock genuine Q500 4K parts and offer Q500 mail-in repair.
