Had a pretty nasty crash with my Phantom yesterday. Lost a propeller during flight and came crashing down approximately 50 feet onto a paved street. All propellers, landing gear and Gopro case were broken. Took my phantom home and hooked it up to Naza Assistant on the computer. The Phantom just beeps. No 7 notes intro sound, no L.E.D.'s. USB is unrecognized. Not a repair I can do by myself. Can someone recommend a place to send my Phantom for repairs? I'd love to get a back in the air soon. Also....note to self. Be sure to check and tighten propeller nuts as part of pre-flight checklist.
