Continued work on the aft battery mounting tray. There are three attach points of the tray to the fuselage. I still have some modification to do with the attach points to beef them up more. I believe two out of the three will be using the 3/4 x 3/4 x 1/8 angle for strength. My son Sean helped out tonight and that was fun. More to do with the mounts before I'm happy with them...
The attach point in the top left will be changed out
