mine does the same thing. says there is not enough light. so a have to set mine on a piece of white paper to get it to take off. I saw one dude try to set his on pavement and it would not takeoff.
Ensure you have good lighting. If you t do,the unit sounds like like it is close to defective. I would contact Yuneec C S and file a ticket with them. Something is not quite righ
Justdt checked it .....the irs status is orange. When I lift it off the ground it turns blue. So I guess it's working correctly . It flashes when the area isn't well lit.
