Thank´s Greg for share all your unvaluable experiences; perhaps it´s usefull too reinforcing wings with CF cloth as I did with my flying wing First Phantom FX 61 VTOL but enlarge them up to fuselaje, that´s looks to give more rigid to the wings too. After your videos and Iskees advertise I´m waiting new motors before try to fly, good quad looks mandatory not to crash 
. Anxious to give a try .
