I'm sure it's a long and drawn out story of why there's no word on an RS module. I saw an orange RS module on two 520s back in Jan/Feb, then poof, never saw another new image with RS. Give it a couple of weeks and I'm sure there will be stories coming out if the woodwork.Weird because you would expect that drone superior to Typhoon H would have advanced obstacle avoidance system and not actually inferior one.
