I've been designing, testing, engineering, integrating, and operating multirotor and fixed wing UAVs (drones) for over 10 years. If you want it done right, let me know. Bid price is negotiable after I understand your requirements.
Design process will include:
1. Operating specification determination and agreement
2. Project plan and scope of work definition with fixed pricing
3. Rough design review
4. Virtualized flight test (x-plane) of rough design
5. Finalized design
6. Structure engineering, Bill of Materials, Manufacture and build process definition.
Optional:
7. Prototype built and flight tested
8. Design refined after testing
9. Final production model designed, built, and tested.
10. Mold creation for composite structures (if required)
11. 3d printed meltable models for mold creation.
12. CNC maps for cut parts, etc.
To continue please define your requirements in as much detail as possible. I will then provide a rough proposal for your review.
