I present you fira: A flight controller! I have made a accurate ish render of the frame we have spent somewhat weeks its just we were trying to make sure it was affordable and have some lists for kits this could be in! It has 4 s12302 Mosfets and a esp32-s3-wroom-1 controller and

I present you fira: A flight controller! I have made a accurate ish render of the frame we have spent somewhat weeks its just we were trying to make sure it was affordable and have some lists for kits this could be in! It has 4 s12302 Mosfets and a esp32-s3-wroom-1 controller and can be controlled entirely via WIFI! I attached a render of what it can be used for :) Its meant for simple tiny drones!
