I have the P1.1.1 and a Gopro 4 black. I want to get a gimbal but I need a few questions answered first... 1. 2 axis or 3 axis? Is the extra axis worth another $125? 2. Are they sturdy? If I crash, is it going to break? Or can it take a couple of hits? 3. How hard are they to install? Cutting, soldering, programming? What am I getting into? 4. Are there any models that are quick release or easily detatchable? If I decide I want to go stunting I would rather have it off in case of a crash. Im sure I have more questions, but these are the main ones I can think of now. Any answers or links to products would be great! Thanks pilots!
