Where to get AC 3.3?

Forgive me if this seems like a simple question to answer, but I have been trying to install retractable landing gear to my quad copter and APM 3.3 is the only software version to allow for this to be functional.

After looking and looking around the web I have yet to come across a download to upgrade to. Can anyone point me in the right direction as to where I can find this?

Thanks for any help that one can give to this matter

Thanks @TCIII, I wasn’t expecting so many files lol. Any direction on which files I should start with?

Connect your pixhawk to your computer, open mission planner, go to Initial Setup, then look at the bottom of the screen for Beta firmwares. Click that and load the latest beta firmware.

You can compile directly from github, but, I don’t think you’re at that level based on your question.

The Mission Planner’s INITIAL SETUP >> Install Firmware page’s “Beta Firmwares” link can be used to get Copter-3.3.
