Default Beginner ESCquestion

Hi all, this is my first post. I am located in Chicago, Il, USA.

I am working on a small radio controlled vehicle, roughly 4 x 4 inches powered by 4 AA batteries (6VDC). I have some experience with electronics, but am totally out of my comfort zone with regards to RC vehicles.

I will be using 2 Pololu gearboxes such as this one:

I have a Fly Sky 2 channel transmitter, model FS-GT2:

The manual is here:

Page 7 shows how to connectthe receiver to motors. The DC motor is connected using an Electronic Speed Controller. Here is my problem.I don't which ESC is suitable for my project. I found thismodel at Amazon:


Will these work for my project? Suggestions are welcomed!

Thank you for your time and assistance. Saga

You are using brushed motors. 99% of the ESC's available are for brushless (AC) motors. You need a "brushed ESC" like this one:

Thanks! Yeah, I did some more research and found that ESCs are usually for AC motors. i did not know that these RC Car motors worked on AC.

The connection diagram that I referenced shows a servo directly connected to the Fly Sky Rx. What would happen if I connected the Rx directly to the brushed DC motor?

Hmmm... thinking about this question. A servo needs a supply voltage, plus a pulse to move the shaft. The Rx provides these three. A DC motor needs two lines to provide power to the motor to make it move. PWM could be used to control the motor's speed, but not direction unless the polarity was inverted. Looks like a direct hookup would not work. Again, thanks for your help. I'll look into the eBay item that you referenced. Sagav
