My drones and their configurations

As well as a software-failsafe I added to Betaflight 3.1.7.

Drones are ordered from most-recent downwards.

Beecore custom-built Whoop

FliteTest Gremlin (TJ's frame)

105mm custom-built brushless

NERFrame/Pink Rocket

A NERF-dart based frame for the QX95 parts while my replacement QX95 frame shipped itself to my house.

Build plans are here if you want to build your own.

QX95

Betaflight 3.1.7 software failsafe implementation

My first (and only right now) drone is an Eachine QX95 with the a copy of a SP Racing F3 EVO flight controller + a Flysky receiver, all on the same board:

This board has no Flysky failsafe (PPM output freezes on TX drop-out) so I wrote a small patch against Betaflight 3.1.7 to report loss of signal after 3 seconds of no change in input.

You can apply that patch to 3.1.7 yourself manually, I've also included it here in this repository or you can just compile the branch in my fork :)
