Oh have you indeed !?
Range depends on many variables all of which all must be taken into consideration. It’s a Phantom 3 standard for a start running on wifi … unless you are in a massive open space which is completely flat with no other interference you are not going to get a massive range even with the very best of all conditions, especially around NI.
The Phantom returns home each time without fail … it’s doing what it is supposed to do. 100 meters is a fine distance, excellent VLOS etc brilliant for a first time flyer.
I would consider the Phantom 3 Standard as an excellent training UAV, only when you’ve mastered it should you consider upgrading.
The one you purchased extremely cheaply was in immaculate condition, owned and flown by a very experienced flyer, it was never crashed, came with a lot of expensive extras and was flown for you in your presence before you purchased it.
The P3S is old tech now as explained to you at the time hence it makes a fantastic training UAV especially for youngsters, also explained to you at the time. At £180 you certainly received an absolute bargain.
I know all this because … I was the one who sold it to you. NO YOU HAVEN’T PURCHASED A DUD !! This UAV will not give you the same distance as a Phantom 3 Advanced or Pro so don’t expect it to. They do not run with Wi-fi.
In my very humble opinion, there is absolutely nothing wrong with your P3S … I think your expectations of its range far exceeds its capabilities though.
Your thread title is both unwarranted and offensive. You as a first time drone owner and flyer have a lot of learning to do before you cast dispersions and speak of vailed threats about other forum members.
