Piper from someone who is doing Aero Engineering and enjoying it loads. I would recomend the degree. Lots of Maths involved however
.
With regard to the UAS and doing Aero Engineering. The students who do less intense degrees have far more time to fly.
You will find that Aero is a full time table course.
I do enjoy the course and the UAS , but the UAS is a large commitment
Just a thought.
Good Luck,
Jonathan
