Hey guys, im running a phantom 1 with h3-2d and fpv setup. Getting a whopping 9 min of flight time with 2800 mah batteries, and 7 min with stock dji 2200mah battery. I NEED more flight time... My friend got the phantom 2 running h3-3d gimbal and I slapped my fpv gear on it. He got 18 min of flight time landing on with %18 battery left.. Amazing flight time. I want to do a shell swap in hopes of getting more flight time. Will a shell swap actually get me more flight time? Who has done it?
