Safety Tip

Rc-toys Multi Rotor safty Tip Keep your PROPS OFF not installed until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe. Never ASSUME the props will not start - removing the props removes the risk.
