Okay, the HSP brand name radio set just arrive.
I cannot find any official website of it. But never mind, we have a hobby grade product over here, so I think they are a good product anyway.
So, let’s figure out this radio set.
This is the radio set.

HSP Radio Set
It is a 2 channel radio transmitter and receiver.
To build our OEM RC car, it is sufficient just to use 2 channel. The functions by channel are as following.
Channel 1: Throttle, controlling the electric motor, the speed and also the direction of movements.
Channel 2: The steering servo, control the angle of turn of the front wheel.
The remote control is kind of self explained. The trigger is for throttle and the wheel is for the steering.
The receivers somehow still hide it’s function to me. There are pins on it that I don’t understand. Well, for a new beginner like me, I guess it is just a normal situation.
The Receiver Pins
This is how the receiver pins configuration.

I bet the 2 pins/row is for battery. But, what the rest 3 pins/row do? And what Voltage, Coulomb, and Ampere should the supply be. And how to connect to the Electronic Speed Control later?
If someone know, please tell me where should I refer this.
Until next time.
