How to Make a Drone / UAV - Lesson 5: Assembly

Let's Make Robots Tutorials

@Demis Only one BEC is normally required to power the electronics (flight controller, receiver etc) as most can provide at least up to 1A at 5V.

42

Thanks sir, and one confusion that if i make a Quad-copter for payload purpose and for payload mechanism i use servomotor then can i operate servomotor by 6 channel rc transmitter…?

43

@demis You can certainly connect a normal RC servo directly to the receiver.

44

Please tell me all material required for makig a drone like which motors should be used battery ,and how to divide current for motor and main thing which material should be used as frame pls reply me soon

45

Coleman benson - you are great and your information and your knowledge is assume .
How to perches this equipment and if have you any dealer in india so plz give me his contact
Thanks bro your and your team work very well

46

@Ravi Kumar That is the purpose of this tutorial. If you need help choosing specific products, we suggest you consider a UAV kit rather than building a custom drone.

@seemant bajaj Thank you for the nice comments. At this time RobotShop sells worldwide (we do not have a specific location in India yet).

Hello sir. Your tutorials are so helpful for a beginner like me! The answer you provided about attaching a servo to the receiver is something I’m confused about. For example if you use a small servo for landing gear or deploying stuff, you connect it to the receiver? Does the receiver gave around 5v to power the servo?

49

@O.H. The ESC is powering the flight controller, which is in turn providing 5V power to the receiver (all power pins). Therefore you can directly connect an RC servo to the receiver and it will simply be operated directly from the transmitter and not need to go through the flight controller.

Thank you !

51

coleman can i use teflon wire instead of silicon wire for brushless motor soldering…?

52

@Demis Be sure to check the continuous current rating for the wire gauge.

53

Hi,
I just realised that the ESC I bought doesn’t have a bec. How can I do to power the flight controller ?

Thanks for the lessons, very helpfull

54

@Bendax You’ll need to split the main battery between the ESCs and an external voltage regulator. If you have a power distribution board, check to see if there is anywhere you can solder cables to get the battery output, which you would then connect to the input of a voltage regulator (choose one which can provide at least 1A continuously at 5V): https://www.robotshop.com/en/power-regulators.html The opposite end of the voltage regulator (Vout and GND) should be soldered to a 3-pin 0.1" standard connector which plugs into your flight controller. The signal pin won’t be used.

I am new to this and am looking forward to building my own. I am going to start off simple and slowly build up but I eventually want an x8. The only problem I seem to have is finding a frame I like. All the frames that I seem to be able to find are for regular quadcopters. Are there any kits or adapters that I could attach to a since motor mount to make it a double mount?

56

@Exeria We have found the same thing - there are not many frames for X8. Please send an e-mail to [email protected] and we may be able to tell you about an uppcoming project.

57

Do all flight controller need receivers and transmitters? thought it could be controlled using an ipad or pc.

58

@Emmanuel You can often connect a flight controller to a Bluetooth device, though there are not many apps which allow for flight control (most of the time it’s just for data telemetry).

59

If i want to control UAV for my own direction without using autopilot, am i need some flight controller?

60

@Will If you want to create a multi-rotor drone, you will need a flight controller. If you want to create an RC airplane, you will not.
