Need help.....brought my Phantom 3 standard to Orlando for spring break. Flying with no issues back in MI. Once I get about 200 feet out and approximately 100 feet up in the air the RC signal is lost and the unit returns to the home. The only upgrade I have done since I arrived in Orlando was purchasing a new iPhone 7. I am flying with a buddy that is using the exact same phantom model and is having zero issues. Please give me suggestions.....
