Outstanding for the details and price of your product. However with the supplied transmitter even with the optical flow installed and the calibration set the helicopter tends to drift. Even the trimming won't correct. And yes it was above the one meter height when trimming. Exceeded expectations for the flight time of the batteries. They were working better after multiple charges. Minus one star for the drifting issue even in dead calm situations.
