I got my P3 a couple weeks ago. I have about 15 flights recorded on it. Tonight i decided to take it to the city (downtown). Chose a semi empty parking lot to take off. As soon as the P3 took off I almost lost control of it. Had to fight wind and some serious control on my part not to crash the P3. I went through the basic checks and was all greened up on the app before i took off. I noticed yellow lights instead of green while fighting it on the air. I took it somewhere else without the traffic and went up without issues. Flew for about 10mins. Again i moved to another location. This time closer to buildings and again as soon as i took off i had to land because it was about to lose control and again had the yellow LEDs and message telling me to stay away from magnetic fields (lost gps). Went back home (semi country area) and flew for about 15mins without issues. Is it not safe to fly in the city? Is the wind making it lose control? I plan on flying it away in the country until im sure theres nothing wrong with it.
