Open Source Grasshopper5 5 inch Long Range FPV Frame Kit
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...
