Recommend materials?

[coolguyrc]

I’m designing this medium sized airplane to carry small amounts of cargo. nothing weighing more than 2-3 lbs though. Anyone have any recommendations for materials to build it. So i can plan out the weight of the plane for the electronics. Need something lightweight and rather durable. also not very expensive pls. (i’ve attached some early designs too

BTW to carry 2-3 pounds you will need a pretty strong setup. In this video I was carrying 4.5 lbs and I have a very powerfully motor and I had to have a wide open to stay in the air...I would recommend something of similar size for your project.
