This may have been asked before, but i recently crashed my P3S into water and about to invest in another. I have been studying both models and seriously don't know which way to go, i love the stability of the P3P but think i should go to the latest model 4. Im not using this for anything other than recreational flying and filming. Any advise from members on this would be greatly appreciated. Im sure most of you that have the 4 have upgraded from one of the others in the P3 range.
