There is no bind pin designed, the receiver has an "autobind" procedure just like with small quad-copters. When switch on, receiver tries to bind with transmitter for about 3s (led is blinking). If receiver find a transmitter (must be also in bind mode) then it records transmitter identifier and works with it. If it can't bind with a transmitter then is retrieves previously bind transmitter identifier and works with it. This way, you save an extra pin and just need to bind only once. After bind procedure, If reception is ok then led if on, if no reception at all led if off, if reception if bad led is blinking randomly.
