How do I sync the controller to the drone?When I turn on the drone and remote, then throttle up to fly nothing happens.
Answer to "What is the mode button on the remote controller for?"The mode 1 is the initial state from power on, the drone will be in a low speed operation for beginners and windless environments. Mode 2 is selected by pressing the mode button on the remote, the drone will be put into high speed operation for faster response and high wind resistance. Pressing the mode button again will cycle back to mode 1 as desired.
