I have a Phantom 4 and without building an entirely new drone, what motors can I put on it to lift about 5-8 lbs? I'll have to keep the 9.5" props (may be able to use 10" b/c of the small size of the frame. I'm doing some cargo drops and need to lift a little more than what it can lift now (about 2-2.5 lbs).
Would I have to change the ESC's, too? Any other considerations?
