Building a drone from scratch. What motors do I get?

[Benjamin Thomas]

Hello! New to this site so forgive me if I've posted in the wrong forum. I'm a newbie electronics hobbyist and I'm about to start work on a project that I've had in mind for a while; building a drone from scratch using an Arduino micro controller and a gyroscope. But I'm having trouble finding the motors that I need. I don't know what I'm searching for, I need 3v motors that I can attach propellers to. All the motors I have looked at have a smooth shaft (https://www.amazon.com/Lethan-Recta...coding=UTF8&psc=1&refRID=YWJKT9Z8Q36CGZWRRA99) so how do you attach a propeller - or anything for that matter - to it?
Does anyone know a good place to buy propellers for small electric motors? And how will I know that a propeller will fit the shaft of a motor?

I'm sorry if my question is a bit vague. I'm just at a loss of what to even search google for.
Thank you!

check out the drone parts at www.banggood.com Check out 'drone motor' and 'drone propeller' selection.
I don't think you'll have much luck with 3V motors. You should consider using ESC "electronic speed controller" to control the motors.

Cheap toy drones use a 3.7V lithium battery. The motors are small and low power then the drone is also small.
If I wanted to build a drone from scratch then I would not use cheap Chinese parts with no spec's, instead I would copy a US or UK model drone and use its parts available at my local hobby store. Isn't that is where the radio control system is coming from, or from China?

No, I'm going to control the drone from a web interface that is provided by an on board raspberry pi zero

Will you use Wi-Fi or Bluetooth? Will the range be far enough? The model drones at the park have GPS and the flight plan is programmed into the model's memory. They have video transmitted back to the pilot watching through video goggles.
A few model drones flew away and the pilots do not know where or how far they went.
