Hey guys. I previously had a P3A and sold it and just now ordered another P3A because I missed it too much. Anyway, my two main questions are as follows: 1. Interested in the DJI black carbon fiber propellers. I like the look of them but want to know if they will make a positive performance enhancement. What are the pros or cons. 2. I see lots of talk about filters. My first time around I never used one nor did I ever consider it. However, now I'm curious. I'm just an amateur flyer and don't use it for any kind of business purpose. Is it worthwhile to buy one? If so what's a good brand that easy to use?
