Thruststand for Brushless drone and other motors

While the most on the market are expensive and mostly oversized for my needs, I decided to make my own thruststand, to measure some motors / props combinations. 

This way I can see how much lift a prop makes at for example 5A or at a specific Throttle %. + of course, at full power.

I added a Protection while some of the “toroidal” props exploded and that is no fun! Safety first. I printed mine in CarbonX, but you can print it also on other filaments.

What you need:

1x HX711 24BIT-ADC-Modul ( https://amzn.to/3nFlUx8 ) - I use a 1kg! Choose yours
1x HX711 amplifier ( the one from the link above has one already included!)
1x Arduino - Nano / Uno ( https://amzn.to/40B709L ) - Nano
1x Display ( https://amzn.to/42YJIMx )
1x some wires ( https://amzn.to/40EBIic )
1x push button ( https://amzn.to/3m9FYHn )
1x On/Off switch ( https://amzn.to/40TomhR )
1x 5V Power Supply ( https://amzn.to/3GbZc6i )
1x Barrel plug ( https://amzn.to/3m0rPwa )

1x ESC ( https://amzn.to/3m3LWts ) - 30A is overkill but it is cheap
1x Motor ( https://amzn.to/3U3YoWy ) - 2205 - 2300kV as example
4x Motor screws, if your motor comes without screws!
1x some props ( https://amzn.to/3K4QS9p - https://amzn.to/3m2krk2 - etc )
1x servo tester ( https://amzn.to/3m08xXJ )

The Display is screwed in place with M3x10mm and a nut inside the box.
My HX711 has M4 and M5 threads, so I needed M4x16mm and M5x16mm to mount it.
 

You have to print at least the box, but I recomment also to print the protector. If you wanna test bigger Propeller, let me know and I can design you a bigger one.

If you are not familiar with writing your own code, you can use this one:
