I'm really wondering about the battery storage compartments also. Even though the dimensions are the same on paper, you can see the differences between the body styles. I'm going to get a P4P, and I'll buy a new hprc case if I need to but I would rather tinker with this one
Thanks Glenn I had to modify it to accept the camera guard on the P3P. Even though the dimensions are the same across the arms, being that the P4P is 100 grams heavier and the body looks bulkier, I wasn't sure if it was taller or if there would be an issue. It looks like the P4 batteries are larger from the pictures then the P3's but I've never seen them in person. Now I just need to get to the store and pick it up
