Open Source Grasshopper5 5 inch Long Range FPV Frame Kit

1. Introduction:

The Grasshopper 5 is a 5-inch FPV frame that allows adjustable angles between the rotor plane and the body, is 3D-printing-friendly, and has excellent compatibility with mainstream FPV drone hardware. 

Not all about science, but all about fun!

2. Grasshopper 5 Design Concept:

I know that designing a drone with an angled rotor plane is not a novel idea. Many similar designs exist, with DJI FPV being one of the most well-known examples. However, none of these designs cater to DIY enthusiasts or are compatible with the current mainstream FPV hardware. Therefore, I wanted to create a frame where the rotor plane could be angled relative to the body and the angle could be flexibly adjusted using 3D-printed parts. This would make it easier for more people to try out this layout and explore its potential benefits.

The design isn't strictly science-based but still exciting to explore.

3. Features of the Grasshopper 5:

• Reduces drag generated by the body, improving flight efficiency.
• Adjustable tilt angle (by swapping out two 3D-printed parts) to suit different forward flight speeds.
• Compatible with mainstream open-source flight controllers such as Betaflight, Ardupilot, INAV, and more with simple configuration.
• Compatible with most mainstream FPV hardware and installation methods.
• Optional wings can be added to further increase flight efficiency during forward flight (coming soon).
• Integrated and well-placed sensors like the compass, GPS, TOF, and optical flow to minimize interference, achieving high precision in position control.
• Supports GPS-based hovering, waypoint flight, autonomous return-to-home, autonomous landing, and optical flow-assisted hovering and position flight.

4. Application Scenarios for the Grasshopper 5:

• Suitable for multirotor drones where forward flight is the primary operating condition.
• Requires autonomous positioning capabilities.
• Long-range flight.
• Carries light payloads that need to face the flight direction.
• FPV Freestyle.
• Other unexplored uses...
