2-channel remote control, controlled by a microcontroller. 
 It has a superheterodyne receiver and not regenerative  like most on the market has. Thus it has greater sensitivity and greater rejection of interference and parasites. It can also work as a Push-On. that means that is ON as long as you press the button. Its range is 100 to 300m. If you put a good antenna in the receiver in an open area, it can reach 500m. Very small dimensions, Can also work with 6, 9, or 24 VDC voltages upon request. There are controls for longer range.
