Was flying around the house and apparently to close to a light pole , caught the blades and fell about 6ft to the grass . Went to retrieve it , flight app had IMU error . Turned off turned the quad back on . Recalibrated flew normal , camera , gimbal no damage to drone . Hadn’t flown for a couple of days . When I started up today needed IMU calibration . Calibrated flew fine took up to 220 ft altitude. Landed then got IMU altitude error . Then took off and flew low altitude, altitude and distance seemed ok . I feel I’m a skilled pilot just got a little to close to the pole as I’ve flown around it many times navigating it and the trees . What I’m asking is if I start up and I get the IMU error again should I send it off for refresh . I’m upset inserted by moderator this happened . Great little drone , I didn’t think I’d like it after flying my MA2 .
