2 - Improved Model made from Styrofoam

So Mengzhen always has a way in giving us surprises.
She made an improved model of the one we made last Friday.
The model was made to be simple which only contains the wing, the tail and the structure that joins the two. We hope to understand a little bit more of the aerodynamics of the plane in this way.


The design is very creative. Below are some of its features.
1) Functions of end plates and structure has been merged.
2) Very little friction with contact surface as the tip of the structure has been sharpened and covered with transparent tape.
3) Adjustment tail allows the height of the tail to be adjusted when necessary


But the model wasn't able to sustain it's flight, why?
A possible reason is that the main wing is too flat.
A higher angle of attack which is likely to achieve more lift would likely to yield better performance.
