Hi @Zoli,
Really sorry about not seeing your response here.
Yes, QuikTune is included in 4.4. I’ve got a new version that we will probably backport to 4.4 and will certainly be included in 4.5.
… but to be clear what “integrated” means, Lua scripts are always separate from the main flight code binary so an extra step to install them on the autopilot’s SD card is always required.
