So i was flying my DJI Phantom 1.1.1 around at low altitudes (7-20ft)and when i put on the new carbon fiber props i noticed that it was really jumpy, which i attributed to the stiffness of the CF props. On top of that if i let off the throttle it would occasionally just accelerate extremely fast vertically. It seemed like i wasn't in control of the drone for a few seconds. After a few times that this happened it did it a final time to about 75ft and i wasn't able to regain control and it just fell out of the sky. Has anybody else seen issues like this? Could this be interference from the Carbon fiber props?
