Are you flying inside? if so that could be the cause of movement. I tried to trim as per solobosses instructions and what I found out it is a lot better to do outside in absolute no wind or a BIG room. I am lucky enough to fly in the high school gym. When I fly inside my home the cx is all over the place. my living room is 12x16 and I try to maneuver into the kitchen onto the table. and objects really change the wash from the blades
