I have recently replaced my drones FC with a new Speedybee F7 V3. It flies well but when I start to get a little more aggressive with the controls, rolling and pitching hard or hitting the throttle up fast, the drone just falls out of the air. Again, it flies good when I'm just cruising around but if I try and do some rolls, flips or putting the pedal to the metal it clunks out and falls out of the sky. I don't have anyway to record my flights yet so I can't upload any examples. Does anyone know why this could be occurring? Thanks
