I hate to start a new thread but my attempts at searches get a lot of threads that don't have the information I'm looking for... Just got a new P3S. After getting home, I started checking out accessories on Amazon. I noticed that many of them are listed for the Professional and Advanced, but neglect mentioning the Standard. Types of accessories I'm looking at are: 1. Carry Case 2. Battery 3. Prop guards 4. Props 5. Whatever else I can't think of right now Anyway, which of these differ from the P and A to the S? Some of the reviews on the cases actually mention how the S fits. But the battery and prop guards seem to be unclear or indeterminate on that. and what other accessories are model-specific? If there is an existing thread or resource for this info, feel free to just point me to it and save everybody's time. Thank you.
