I didn't see a section for drones, if I missed it please move this. I was given the above mentioned drone for Christmas this year. This is my first drone. I would like some help and guidance on adjusting trims. The controller has push buttons for adjusting these, but I am not seeing any improvement. When slowly powering up the drone to get it to hover a little off the ground it lifts one side and slides across the floor. It seems as if two propellers spin faster and start spinning before the other two. Thanks in advance!
