I'm looking for a small case or backpack. Doesn't have to be able to withstand a nuclear blast or anything like that, since it spends 99% of it's life in the backseat of my truck or in our camper. Just want something to keep all my stuff together and easy to get to. "All my stuff" just means the P4, the transmitter, charger, 2 batteries (don't plan on having 5-6 batteries ever), rotor blades and an iPad. Thanks in advance for anything you folks can recommend!
