So my dad is in his 60s and owns a farm. Being in Florida he gets some pretty bad weather at times the fences keeping livestock in get damaged/destroyed. He had the idea of using a quadcopter to patrol his property line so he can inspect it without all the hassle of getting the 4wheeler/tractor out warming it up, opening all the fences while keeping the horses in the right pens and so on. I have a Phantom 3 and would be great for doing this using waypoints or flying it himself. Now he is hesitant due to the price but with the 4 coming out prices are getting more tempting for him. The dilemma here is what version to get. The area he would like to cover is only about 10 acres with some small trees and windmill in between the furthest reaches. Would the P3 Standard do or would it be better to go for the Advanced.? I have no experience with the standard so i am unable to give him any input. The standard is currently selling at a reasonable price but i do not want him to be disappointed in the performance or lose signal and crash. Any input would be great. Thanks guys.
