All answers needed about differential steering

Lets assume youve bought a Spektrum DX6 and BR6000 Receiver.

The Transmitter has 2 control sticks and each stick controls two channels...there are also 2 switches that control one channel each.

A total of 6 available channels.

Assume that your bot has 2 motors one for each side ...so we need to control the speed of these motors.

Purchase a suitable dual controller or two single controllers.

These controllers come with leads that will plug into your receiver and will also come with 2 battery power supply wires and 2 or 4 wires ( single or dual controller ) that will go to your motor/s.

Then simply attach the correct wires to your battery and motor/s and plug in the Radio control wires to the receiver.

The reciever then takes commands from the transmitter and passes them on to the controllers which in turn vary the speed and direction of the drive motors according to movement of the transmitter stick.

A 3rd channel on the receiver ...taking instructions from the transmitter... would be used to operate any switch or speed controller required for a weapon.

Helpfull or clear as mud?

Correction:-

Not ALL controllers come with the power and motor leads attached some have blocks that you must add your own wires to.

Heres a pic of a Sidewinder dual controller showing the main power and motor leads at the front... in the background you can see the wires that would plug into your receiver.

And heres a smaller one also showing the connections ... this one has an extra 3rd channel to aid inverted driving.:)

So in short:

You need a transmitter (tx);
this controls your receiver (RX);
Attached to the receiver are 2 servo wires;
Attached to those wires are either (a) 1 dual motor controller or (b) 2 single motor controllers;
Attached to the controller(s) are the motors that spin the wheels.

No matter how you steer, tankstyle, steering wheel, or single stick, you will always have that setup. For drive you will always need 2 channels.

O.K thanks all. Woody the advice is Helpful. I do get it now. And so if I want to also use an axe with it, what do I do? I know I dont plug into the co2 canister, so what do I do? Thanks for the advice though.

Thanks,

Rob

Some pneumatics research first.

Then ask some more questions....

Note that the pneumatics will be turned on and off by a R/C Switch ...this will be plugged into a spare socket on the receiver and activated from the Transmitter.
