How about this?

Well?

That is simply false.

Bothering as in: - Asking unclear questions (what is "lightweight"?) - Asking even more unclear questions ("How about this"?) - Bumping threads after noone replies to above questions - Accuse people, which spent a lot of their time on the forum to help people of being non-constructive without proof

Also, please read you own signature.

probably electric.

most likely you'll have too much mass if you try it with something like 440 Hemi's.

my response makes as much sense as your question.

Those are 56 grams each and require an ESC.

Micro or Nano size quadcopters typically use brushed motors like these: http://www.hobbyking.com/hobbyking/store/__42098__0716_Replacement_Brushed_Set_HobbyKing_Pocket_Quad_V1_1_Quadcopter_4pc_.html

They weigh 15 grams each and only require a small MOSFET and resistors.

Personally and as my opinion I would suggest you this ^^ 55$ free shipping Buy an extra battery 3S LiPo 2200 mAh with 15$ Build your own frame and electronics, learns how to control ESC with Servo Lib. and use the small nRF24L01 to control wirelessly your quadcopter, ow and as well buy a MPU6050 to program your own self balancing system using PID.

Thanks, D.60

I don't think a quadcopter with 10" propellers could be called a "very small super light quadcopter"! It would have to be at least a 360-class (360mm diagonal motor-to-motor) frame to keep the props from hitting each other. For "very small and super light" I would expect something less than 1/3rd that size.

Well OP suggested this:

Which needs 9~10inch prop so I thought if he likes to use this why not what I’m gonna suggest.
In the other side why to waste money on small components when you can build a normal size one, practice
in electronics, learn new things and after a while having a normal scale quadcopter to play :smiley:

But that’s just my opinion, I don’t really know what OP really needs, you can post one thing but your
heart need something bigger :slight_smile:

But could a micro/nano type design (with motors like those) be able to carry the Arduino necessary for control and the battery necessary for power? Can they provide enough force?

If you manage to build a really lightweight frame and use a small battery (<1000mAh, 1S) it should be able to carry a Micro or Pro Mini for some minutes.

Ive never used brushless motors or an ESC before!

So for a motor like this one: http://www.hobbyking.com/hobbyking/store/__17922__AX_4005_650kv_Brushless_Quadcopter_Motor.html Do I use one ESC for all 4 motors, or do I need an ESC for each motor?!

Also, is this a compatible ESC with an Arduino? Will it work with the previously mentioned motor? http://www.hobbyking.com/hobbyking/store/__6455__HobbyKing_SS_Series_8_10A_ESC.html

And just for the sake of argument, lets talk about brushed "normal" motors. I know they arn't that great, but I saw this video (https://www.youtube.com/watch?v=qa_x93JQhNM) where they use brushed DC motors, like these: https://www.amazon.com/AC-Infinity-HS1238A-Cooling-120mm/dp/B004YTSB7C/ref=sr_1_1?ie=UTF8&qid=1465524296&sr=8-1&keywords=+axial+fans

WesleyRTech: Also, is this a compatible ESC with an Arduino? Will it work with the previously mentioned motor? http://www.hobbyking.com/hobbyking/store/__6455__HobbyKing_SS_Series_8_10A_ESC.html

Yes to the first. No to the second. The motors recommend a 20 Amp ESC so a 10 Amp ESC would likely fry. They are both compatible with a 3S LiPo battery (3 cells in Series for a nominal 11.1 Volts). The motors can work on 2S or 3S. The ESCs can work on 3S or 4S. You will need an ESC for each motor. The video from TPAI clearly states that the fans he used had BRUSHLESS DC motors.

There is nothing wrong with bumping a thread after a reasonable amount of time has passed.

WesleyRTech: Well?

Less than one day is not a reasonable amount of time. Do not do that again.

Please do not buy unnecessary stuffs :D you will spend money you will fail with your project and get angry because nothing is working as you expected.

You need 4x Brushless motor and yes you need as well (4x) ESC for each motor.

|477x500

If your motor require 20A ESC buy a 30A one, why? If your motor needs a 20A ESC and you use a 20A one and press/move to full throttle for long time the ESC will heat up and burn which can cause damage as well to your LiPo battery and get on fire.

If you use a 30A ESC on a motor that require 20A ESC the even if you full throttle the ESC will have a space of 10A the ESC will not heat up so much or burn and you will be safe using / playing circuits/ESC.

  • Also you don't need a BEC, BEC is used to power up with 5v the receiver, nowadays ESC got already implemented inside a BEC and a 5v output.

Here is an example how to connect ESC with arduino: |500x378

To control ESC you need: The ESC got 3 wires for the brushless motor 2 wires for the LiPo battery and 3 wires Ground | +5V | Signal

You need to connect the Ground to your arduino and the Signal to arduino PWM pin, you can connect the +5V ONLY and ONLY if you want to power up the arduino, if you power up the arduino from other source do not plug the +5V from the ESC and do not plug all 4x +5v from ESC to arduino but just one if you want to power up the arduino.

Let me get this straight. So to get this thing off the ground, I will need

1x Arduino 4x Brushless motor 4x ESC 1x Lipo battery (Or 4x Lipo battery?) 4x Propeller for motor
