The stab adapter make sure that the Gong V2 fuselage stab connects to the aluminium profile. The stab adapter locks in the battery and allows to pull it out of the profile for charging

The battery has an integrated 8A BMS that allows it to be charged without accessing the balance leads

The Servo adapter is next. The version in the picture still has a lot of work to be done
