I'm working on designing and building a multirotor drone to lift a ~3kg payload with a group at my university. My role is to help design the frame, and while I have a few ideas, I need some advice on the best way to get to a finished design.
Obviously the key challenge here is to minimise the weight of the airframe without sacrificing too much in terms of strength/stability. I've played around with Fusion 360's generative design to try to come up with some 3D-printable parts, but I'm now wondering if this is overthinking the problem.
If anyone has experience building heavy-lift drones, I would greatly appreciate your advice.
Some specific questions:
- Is it feasible to 3D print part or all of the frame? If not, what is my best option?
- Would an octocopter be better/worse than a hexacopter configuration?
Thanks in advance for your help!
