Firefly Q6 4k (mini)Camera ($69)

[Winston]

It's 4k 24fps capable, but its 1080p 60fps mode would probably be more useful in rocketry (unless we find out that it's just frame doubling 1080p 30fps although since it can do 4k 24fps, I doubt there's a hardware limitation that would require that fudging):
