Rx and speed controller

What does the speed controller do? Doesn't it get signals from the Tx?

A speed controller gets a signal from the receiver, and accordingly it will move a motor in a certain direction. it gives you more control because you can increase and decrease the speed of the motor.

The other option is an r switch and relays to control a motor, but thats more a full throttle off kind of thing.

Oh thanks, so you don't have to have it to make the robot run?

if you modify a servo to make them rotate, you can put those on the receiver and you can move without speed controller.

for normal brushed motors you can use speed controllers or switches+relays to activate them.

Oh thanks, by the way your robots on the videos place in my other post.

Which one?

The one called "AWS 21 Greatest hits" in the antweight section and in the "pics and videos" topic.

Do you need a extra speed controller for a spinning blade weapon? I looked at the speed controller manual and it didn't show a connector for a saw weapon. I looked at the motors for the a saw and it said you needed a special speed controller for the motors. It's really confusing

. There is a speed controller with a AUX(auxiliary load connection) I'm not sure if that's the connection for the weapon motor.

Oh sorry I just figured it out. The AUX is for the weapon motor. Sorry about that, how stupid of me

If the weapon motor is a normal brushed motor with just two wires the Aux should drive it. If the motor is a brushless motor with three wires then you will need a special brushless controller. You also need to check that which ever controller you use its current rating in Amps exceeds the stall current of the motor.
