@robolink_leila Thank you so much for the help. I am not sure if the calibration helped or the pictures showing the correct way the propellers should go. Either way, it is flying now!!

I purchased a Codrone a few months ago. I have only used it about 3 times. During those times everything worked fine. The last time I tried it will not lift off the ground. I have checked to see if there is damage to any of the blades. I have replaced the batteries. What else can I try?
