Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer specialized in the Industrial Robotic field.
I assume you need a mechanical/engineering drawing for a new drone, that's why my bid is so high.
(btw - during the development, the price could differ, accordingly with your requirements)
While I could design the light weight skeleton I will keep the same time the functionality and structural strengths of the drone.
Upon our first discussion, where you'll give me all the dimensions and other features of the components you want to use, I'll come up with a primal model.
On this rough model, with your assistance, I'll make the modifications/adjustments/changes until the final outcome will be reached.
Once the final model approved, I'll send you all the necessary files.
