I've flown my Phantom 2/H3-2D/GoPro about 4 times with no problems. With the most recent flight, after I started the rotors and hold the throttle stick upward, the propellers move faster than the idle speed but don't spin fast enough to lift it off the ground. The controller & Phantom are both freshly calibrated on the computer with batteries fully charged, the compass is calibrated, gimbal is functional and the Gopro has power. I'm still pretty new to this stuff but I just received the AVL58 set in the mail so I'd love to get this going ASAP! Thanks!
