Hi everyone, I am new to the RC world and have spent the last few days researching RF etc and after some advice on motor compatability with 2.4ghz receiver modules.

My friend recently made a Cable Cam prototype in his garage, he stripped down a cheap £15 RC car and used the internals of that and made a very decent cable cam, however one of the main flaws being the RC car was using infrared, so it didnt really work outside of his garage.

He wants to take it up a notch and has come to me for advice but I am way out of my depth, but it is something I would love to get to know more about and I am pleased he has asked for me as a parter to collaborate with.

I have been looking at the Fly sky FS-i6 and receiver, this is more than adequate for what we require, if not overkill.

The thing I am unsure about is the motor. The current motor we have is a 7.4v geared motor out of a cheap RC car. This motor only has 2 wires.

Now the setups I have seen people using is Brushless Motors connected to a ESC then connected back to the receiver. These motors have 3 wires I've noticed.

Basically can you connect a 2 wire DC geared motor into one of these receivers?

Or is there a brushless motor available which could perform at well as a geared motor when is comes to torque?

I understand this is a broad topic, any advice in the right direction would be very much appreciated.

Thanks guys

The output of the receiver is a Servo signal. The 3 pins are power and a PPM signal. To control a motor you need an ESC (electronic speed control) if you want to control the speed or a RC switch if you just want to switch the motor. I would just say to get a simpel ESC with a forward/reverse control. Because your motor has 2 wires, you do need a brushed ESC and something with a currenrange of 10A is more than enough.

no a direct connection to receiver will not work.there are 2 in 1 motor with hidden esc inside motor can that will plug into rx but you must add a battery to power system. motor with esc.no getting around that with that air radio some esc will not bind so maybe find 1 that will.much more detailed info here might take a look..Electric RC info, how-tos and such - TJinTech

You could probably hack an old servo to do what you want. After all, a servo's controller board is basically just a low-power ESC. I hack up old servos and use them as remote light switches and winch controllers for my RC vehicles. If that cheap RC car motor doesn't draw more than a few amps you would wire it into the servo controller board where the original servo motor was connected. Or maybe use a complete servo to move the cable cam. It is fairly simple to modify a servo for continuous rotation.
