Problem:
The Vertical Stabilizers have too much lateral movement as seen in clip below. Having a wobbly vertical stabilizer is sub-optimal for the competition drone as it will likely negatively impact the stability and control of the drone.
Why Are The Vertical Stabilizers Wobbly?
The main reason that the vertical stabilizers are wobbly is because they are attached on top of the stabilizer, which is wobbly, (See video below).
However, it was noticed that the side with more clearance between the tail and tail-frame 3d printed piece was more wobbly as it has more space to bend.

Design Solutions:
There are three unique design solutions which can be implemented to minimize the vertical stabilizers range of motion.
Utilizing inner L-Brackets: Here, one side of the L - Bracket is adhered to the vertical stabilizer, and the other side is bolted into the tail. The force from the bolts would be distribute over a large area by the aluminum plates.
2. Utilizing outer L-Brackets: Here, large outer L - Brackets are adhered to the vertical stabilizers and bolt into the tail to hold the vertical stabilizers securely in place. The force from the bolts would be distribute over a large area by the aluminum plates.
3. Utilizing Screw and Elongated Tail-Frame Connector: Here, the sturdy 3D-printed tail-frame connector has been extended to allow the vertical stabilizers to bolt directly into them. The aluminum pegs which are adhered inside of the vertical stabilizers cut and tapped exactly at the bottom of the vertical stabilizers and a M5 bolt tightens them to the tail-frame connector.
