For Newbies. (like myself)
Number one do not listen to what they say, in any sort of wind do not fly, the quads are to light.
Number two make re-set part of your preflight preparation.
Number Three keep your eyes on the quad not the controller remember it might be quite still on the ground but 20mt up may be a different story.
Number four if like me you have a Syma X5 note its range which is 50 meters for myself I have found a park which is 200 x 160 meters.
