Thanks Mike currently I am flying a dii wkm,F450 quad,also I fly a jdrones hex,apm 1.4,but the wkm is my weapon of choice because of ease of setup +seems very reliable thus far but I am not comparing apples with apples am I. Also i fly a raptor 50 nitro with skookum 720 controller,& my scratch project is a custom frame of epoxy fiberglass over balsa for the centre pod & aluminium arms 25 *15 mm motor to motor 1200mm (hexa) .Motors tiger 4014/11 330kv,Tiger props 15/5, Esc's are AKE 40 AMP OPTO'S,still undecided on flight controller maybe i will use the wkm out of the f450 or buy a new YS X6 F/C ???,& finally am I a seasoned vet,no not really,still got a long way to go & a lot to learn,cheers.
