I am thinking of building a uav to fly the new blackmagic micro studio camera. I would like to hear some advice from everyone on frame size, gimbal, ect... I already have several 4s 10000 mah batteries and was thinking of mounting 2 if it would increase my flight time instead of having to buy all new bigger ones. So the frame would be a larger one but I don't want to over build and be flying something so big its hard to pack up and needs a wide open space to fly. I do a lot of flying in parks around trees. I not flying in woods but something hugh might be restrictive. Also I was wondering on any gimbal suggestions. Thanks for any helpful input.
