4-Channel, 2-Flavor Remote Control
Cheap ISM-band radio modules are great for making simple remote-controller toys. When a greater degree of control is needed, for instance when running servos for controlling a model plane's rudder, elevator, aileron and a brushless motor while at the same time receiving feedback from each of those actions, you need something like this 4-Channel, 2-Flavor Remote Control with XBee or nRF24 radio modules.
