I'm a portrait photographer that is looking to photograph some subjects at the edge of a cliff face, about 40-50ft from the ground, but I'd need my speedlight floating out in the air in order to get the look I'm after. I know another photographer has used a Phantom to do this, however, I have a Mavic Pro 1 and was curious if it could handle a payload of 19oz/540g? I will be upgrading to the Mavic Pro 2 soon, would it be more capable? Thanks.
