This is KO PROPO MR-8 2.4GHz MX-F 8-Channel Receiver. MR-8 is the dedicated receiver for the MC-8 (devise that receives signal form the transmitter and outputs electrical signals.). Signal format from the MR-8 is the same as general RC devices so it can be used with our RC car devices and also RTR models. The MR-8 is easy to use by connecting to the channels that you want to use with the connector of each RC device. For example, if you want to control the steering with CH-B of the MC-8, insert the connector of the steering servo to B of the MC-8. Turn on the MC-8 and then the MR-8 to control the steering with the MC-8. Signal format from the MR-8 output are PWM (pulse width modulation). This is the same used for general devices of RC cars, so you can connect it to a micro computer board like Alduino and capture signal.
