How to switch to REP Beta version?

To enable the beta channel, you must have downloaded your favorite REP’s package from the store after the update to v4.0.3.
Inside the new zip, you’ll find a set of skunkcrafts_updater.cfg files. Put them in the aircraft’s main folder and you’re good to go. Just select the “Beta” channel in the SkunkCrafts Updater’s settings.
