Have been cautious flying my P4P and MP close to water but decided to give it a go with my Spark. Flew several batteries hovering 3 to 10 feet above and around various water elements. I flew in close to get some waterfowl pictures and the Spark worked like a champ low and slow.
My P4P and MP can have issues near water due to obstacle avoidance so I tend to turn that off. Must be that the Spark's oa is less sensitive which is good since I like flying close to water.
