4-Channel, 2-Flavor Remote Control
Cheap ISM-band radio modules are great for making simple remote-controlled (RC) toys and other RC devices which need nothing more than throwing some switches on and off and running a couple of motors. However, when a greater degree of control is needed, for instance when running a few servos for controlling a model plane’s rudder, elevator, aileron, and a brushless motor while at the same time receiving feedback from each of these actions, your plain simple radio control is, ermm … too simple.
