Brushed Indoor Hovercraft

It's a hovercraft designed for very flat surfaces, such as wood and ceramic floor, does NOT work outdoors.

To complete the model, you need:
8520 motors * 2
Brushed ESCs * 2(I made one on my own using irlr3103 and attiny)
M3 screws *2
9gram servo * 1(this is designed for emax 8gram)
4 channel radio system
several 500-600mah batteries
60mm propeller and 45mm propellers
cables

These things are easy to acquire if you play brushed racing drones
It is quite tricky to control.
