At first what used to amaze me were the shape and the design of
how the propellers work and how the wings are useful, I began
seeing a planeto see planes from a whollywhole different perspective
As a project at college I would like be immersed in one involving UAV.
This sentence is kind of awkward.
I have been planning a rhombus shaped design
Also kind of awkward and unnecessarily wordy.
I have been planning a rhombus shaped design, the benefit of which will be the UAV could just stop in mid air and go backwards, left or right without turning.
which would allow the UAV to just stop in mid-air
With these capabilities, a UAV will be successful
It won't have to take a long turn while it might get
shootshot down and loose important data ,or objects and most importantly the UVA will get destroyed
This sentence is also kind of awkward, especially the second half.
As far as I have searched I haven't found any design like this yet.
"As far as I have searched" and "yet" are kind of redundant - you could cut down on this sentence.
You could cut down on basically all of the sentences I found awkward. I really like the first half of your essay, but the second half doesn't flow quite as well starting from "as a project in college"
