I'm wondering if the parachute system I installed self deployed because of cell towers . The parachute is only supposed to deploy when the phantom flips to 80 degrees but I watched it open as I was hovering, panicking I tried to slowly lower it but that seemed to make the parachute shoot up and the strings wrapped around the motors causing it to fall to the ground. You can see the camera shake as it springs out around 8 seconds in. Luckily it was low at the time and It landed on a car tyre (thank you fly tippers) so it just has minor scratches.(update needed new camera) The parachute System is one from maplin designed for the Hubsan X4 but Ive modified it to fit.

I noticed after only from video footage and healthydrones log that there were cell phone towers in the horizon and I also had a lot of gps errors in healthy drones. Could this trigger an electronic gyro ?
