Hello, i'm new here 
and i want to buy a gift to my husband...i thought to this: XK Aircam X500 X500-A Quadcopter 2.4G Aerial Photography With GPS - Best-Quadcopter ...but I'm not good at these. Can someone help me to choose?
Thats a difficult question.
Has he any RC experience.
Why a quadcopter. Fun , photography?
They can be rather difficult to fly and its fairly common for a novice to crash first flight.
Why not build one himself? Based upon Arduino?
