Hi all, please go easy on me i am new to phantom 3 advaced and have only basic knowledge of the drone and its operation. I have searched without luck on my issue.... i recently purchased a damaged phantom 3 advanced as the previous owner is not at all prepared to work damaged drone. So i picked it up for a steal.... not knowing What is wrong with it . Lol this can get expensive quick so i might aslo mention iam on a budget ... My problem is the drone was crashed into a lamp post smashing the camera completely and has been removed prior to me receiving. The legs are bent one snapped but seems to have not damaged the cable that runs down each of the legs.... i turn it on with green light on controller on and the red light on the uav flashing red yellow and green with no connectin.. and ideas to get me in the air without a new camera i will definitely be adding one in the near future!I will reqire a gps as iv lost a much cheaper syma amongst houses with great disappointment. Anyone can help even walk me through trouble shooting . I have reasearched this site and believe it maybe a ceramic gps antenna but not sure to be honest. Thanks guys fly on!
