Newbee here...Lost GPS signal and drifted into a tree, fell about 20 feet and broke the gimbal mount and the gray and black wire pulled out of their connectors. I soldered them back on, replaced the mount but now my range has decresed dramatically. I loose video at around 300 feet and then get the RTH prompt. Has an antenna come loose? I'm going to do a IMU calibration as I got that warning along with a compass malfunction error too. Any help will be appreciated!!!

Hello jjepilot, it looks like the receiver in the aircraft are not in good status after the crash. I'd suggest you to get in touch with our tech support via support@dji.com or http://www.dji.com/support/product/phantom-3-standard and send the drone and RC for diagnosis.

Thank you!
