Hi dharanistark07!
Welcome to the forum!
Not to demotivate you in any way, but have you previously worked on any type of multirotor or flown one ?, The reason behind my question is that a hexcopter with a weight of 5kg is a big setup which requires alot of flight experience along with alot of experience to build it, and lets not forget the investment that can cost a lot ( above 40k).
My suggestion to you would be start small with a 450 size quad which has a maximum weight of 1.5kg ! It's easily available and a good platform to learn how to fly!
That’s good advice.
I find a lot of college projects to be over ambitious, mainly because the participants have no prior experience of flying either a multicopter or even a fixed wing RC airplane.
A look at SAE/Boeing results over the years shows that Indian teams score well on paperwork, but often ZERO on flight score. Because they can’t do a successful flight.
Please avoid this trap. Get some flying experience before you start on 5kg hexacopters!
Best wishes for your project.
