Recommendations on propellers/controller for over 100g body. Answered

Hello everyone,

I am currently trying to build a DIY drone. I have never involved myself in any sort of creating drones.

My current project is about making a drone with a morphing body we created. Previously, we just purchased a pre-made drone and took apart all the necessary components and re-attached all onto the morphing body. But the drone we used is this model : Holy Stone HS170 Predator Mini RC Helicopter Drone 2.4Ghz 6-Axis Gyro 4 Channels Quadcopter Good Choice for Drone Training

This product can make things fly when the weight is over 30~50g.

Would you be able to recommend some products or any sources that can be useful for building a DIY drone?

Thank you!

There are a few websites that deal with open source drones as well "alternatives" like Arduino or Raspberry based types.
In many cases you don't have to re-invent the wheel, you just need to look and find the right wheel for your needs ;)
But if you start developing from a toy in the hopes to create something that otherwise costs close to $2000 then you will end up paying a lot more than what you bargained for.

It is like trying to make 50cc China dirt bike look and perform like a Harley.
Do some Google searches for DIY drones, controllers and such.
You will quickly find websites giving you good ideas.
Get a picture of what you really want from your custom drone, look how this done inother projects or commercail products.
Then stap back, reconsider and find the parts and solutions to make it work without the need to develop from scratch, apart from the body of course, being custom and such.
Consumer drones are these days capable of autonomous flight, obstactly avaoidance, self recovery, GPS guidance and heaps more.
And even if right now you might think those things are way out of your reach: You might be surprised what the drone community already accomplished.
There are ready to go, modular controllers available for example.
You can add a GPS, camera, stabilisation, even additional outputs to activate things like tilting frames or rotating rotors for a better directional control at very low speeds.
It is still a matter of price in sme cases though as you won't get quality for peanuts, especially not if requirements are far above of what a hobby pilot shooting holiday videos might need.

A really good start is always physics.
Learn about what a prop needs to produce a certain amount of lift, what requirements a suitable motor, battery and controller would have, how much weight it all has.
Same for basic aerodynamics.
For example no point building a fancy working and looking drone if the wind drag at high flying speeds makes it unstale, hard to control or even fail.
There is also the option of dedicated clubs where you can have a chat with people and can get a close encounter with high end drones.
Trust me: When it comes to starting from scratch then a few hours of personal exchange with the right people can save you endless headaches and frustrations along the track later.
