AR 900 Wing backing plate

The plate that goes on the wing to connect it to the fuselage. This plate is designed to pull out the screws in the event of an impact on the wing so that the wing comes off without breaking. There are 3 holes so you can use a new hole if one gets stripped out. If all 3 holes get stripped, you'll need to replace the wood backing piece(s) that are inside the foam - inserted from the bottom of the wing.
