I currently use my M2P for photo mapping missions. as its supported by Dronedeploy and some others. However depending on the overlap parameters and area, sometimes these missions take forever, and multiple batteries. I've flown mapping missions that have taken up to 10 batteries to complete! I'm considering replacing this with the M3E - i'm thinking at a minimum the mechanical shutter will allow me to fly similar missions at a higher speed and reduce the time to complete. I know right now that drone deploy doesn't support the M3E and I will be stuck with DJI pilot for awhile. Other than that, are there any other disadvantages i should be considering? Note I also have an M3 for standard photo and video missions, and the M2P is just for automated mapping work.
