I was flying with a buddy who just got a storm racing copter. Long story short, i let go of the controls to look & tell him to be careful (i was at about 40 ft & we were in a wide open field), a second later i look back to see my P3A fall out of the sky. Could the controllers have interfered with each other? It was as if i CSC'd but without touching the sticks. The body & landing gear are banged up but the motors, gimbal, & camera seem fine.
