With all the negative post on here " I AM GUILY MYSELF OF A RANGE RANT" I want anyone looking to buy a p4. I live on a island in Alaska and have the only P4 "as of now" and fly with friends that have phantom 3 pro's and they all want to add a p4 to there collection. They are not perfect but what is they are still amazing fun if you forget about what it won't do and enjoy all the amazing stuff it will do. I have got weak signal at less then 1 mile when I thought it shouldn't but have also got close to 3 miles stock at a later date and was amazed even though I did not come home and post a Rant on how great my range was today. As far as battery goes it sounds like 28min was on the heavy side but competition was tuff and maybe somehow someway they got that I have had 24 min flights without doing any special battery saving technics! Anyway I hope this helps someone out there the P4 is not perfect but I sure love mine.
