This is my Air65 Hovercraft. To set it up in Betaflight you only have to set up a custom Mixer. It is great fun to drift around and a good way to reuse broken Matrix 5in1 boards. Have fun building it!

Print settings:

0.2 mm Nozzle

20% Infill

PLA or PETG with Standart Temps

2 Wall layers

Custom Mixer CLI Commands:

Copy & Paste these in the CLI shell in Betaflight 4.5 or newer.

Assembly:

All parts just need to be screwed down or press fitted in. You can glue down the cam or dont use it at all. By adjusting values in the Mixer you can change speed and responsiveness.
