My friend and I are making an RC airplane.
Parts:
I want to connect my receiver pins to an analog in pin on the Arduino Uno.
Then I want the motor and servos connected to the PWM pins.

How do I do the connections for the receiver? The 5V or from the 11.1V?
How do I do the connections for the servos? Using the 5V and GND from the Arduino?
How do I do the connections for the motor? Using the 11.1V and GND from the 11.1V battery?

Have a look out for posts by DuaneB. He has some good information on RC stuff.

Hi,

If you visit my blog you will find most of the information you are looking for.

A good starting point is to select the 'projects link near the top of the screen, from there, scroll down and you will find a section called 'interfacing with rc equipment'.

Scroll down a bit more and you will find another two sections on the servo library and common problems with servos these will answer some of your other questions.

Site didn't really help. Was for RC Cars not RC Airplanes. I have a RC Airplane.

Planes are cars, robots and boats, its all the same.

Same signals, same techniques, same code.

The problem is that I don't understand how to do this "special" technique.
How should I power up the receiver, 3 servos , and 1000kv motor using the 5V from the Arduino  and 11.1V from the battery?
(Also, should I also power the Arduino using the 11.1V?)

Actually the power flow is from the 11.1v battery to the ESC (which most include a 5vdc BEC output), the ESC +5vdc output can then be used to power the servos and the arduino (via it's 5v shield pin).  Be sure your selected ESC is rated to handle the battery voltage and the motor voltage and current requirements. The motor's Kv rating only tells you the maximum speed of the motor per volt, not it's maximum voltage rating and current requirement.

There is no datasheet for this motor. Why? I don't know.
This is the motor: www.hobbypartz.com/40tyoubrmo.html

If I use that BEC 5V DC output plug, should I still use my BEC?
How much power does an Arduino Uno R3, 3 9G servos, and a 1000kV motor (see link) need?

Does anybody know anything about this motor?

I don't think you connected the grounds, Dave.

I think I'd ask the supplier.
Just a thought.

HobbyPartz is a big company. Who is the supplier that knows about the product?
