I bought these filters off of amazon awhile ago for my phantom 3 standard http://www.amazon.com/Phantom-Profe...148&sr=8-3&keywords=phantom+3+standard+filter Wondering if anyone has tried them out? They seem to work fine other than they hit the ground when first turning on the phantom and when I shut the phantom down. Also, my biggest question, is if the added filter could be causing the gimbal to struggle in flight. I have never had a gimbal error or anything like that but it seems like the gimbal almost gets behind or something. The horizon will get out of balance and it take a while for the gimbal to catch up and straighten out. Any thoughts would be greatly appreciated.
