Lover Jet: RC F-22 Raptor
A lover, not a fighter. :warning: Not to mock or make light of warfare
A 4-channel RC system consisting of a Arduino Nano-based transmitter and a cardboard F-22 Raptor jet powered by brushless propulsion. It uses NRF24L01+ transceivers for communication. Made this as an introduction to aerospace systems, more to come :)

Questions
How big is the Lj transmitter PCB?
It measures 130 × 62.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lj transmitter use?
15 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lj transmitter KiCad files?
From the information-fiend/lover-jet repository on GitHub, at the commit this page was made from: the board is PCB/lj-transmitter.kicad_pcb and its schematic PCB/lj-transmitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lj transmitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask information-fiend before reusing the design.
