Added an AIO camera to the X520 and took it for a test flight. Powered by 2s 750mah, @ 6mins of flight. Take off from anywhere with this - For vertical take off you set 3-position switch to V-mode, throttle to mid-range, press the take off button and its up. To fly horizontal after vertical take off, set 3-position switch to 6G mode (1 down from V-mode). Good training for flying wings.
Yes, switch to 3D-mode (1 down from 6G mode) and it's ready for flips and rolls. I tried it and was in trouble real quick, switched back to 6G mode (1up from 3D mode) and it leveled off and corrected itself! Good intro to flying wings!
