Have had two instances in the last two days where I have lost control of my phantom. One resulted in a crash and one I got control back after a fair length of time. Is there anything out there that can scan and show if there is any signal that may interfere. Would be great to monitor an area before taking off to see what the likely hood of this happening would be. The problem I had tonight was near a big Ferris wheel. The Brisbane Eye, about half the size or less, than the London eye.i took off near it and had my back to the wheel and the phantom in front of me. I maneuvered a bit so I would be higher than the ye so I could see what the view would be like if on the wheel. Then I when higher and moved a bit to the right. Then I had no control. The phantom flew over my head and was heading to a building. It then stopped and hovered. Lights were normal, blinking green and the others red. When I yawd left the copter would slowly come down. But then it wouldn't do anything and just hovered. Then about 30 seconds I had control again. No switches were moved or anything, just could not get control. Any ideas ? Would the wheel cause interference with all the metal? Or was there a signal there I would have known about if I had some sort of scanner? Suggestions anyone?
