| Antenna Weight | 2g | 0.5g | 2g |
| Coaxial Cable Length | 55mm (default) | 90mm (default) | 90mm |
| Wide Power Input | 3.1V-13V | 3.1V-13V | 3.1V-13V |
| Transmission Power | Max. 500mW | Max. 500mW | Max. 500mW |
| Built-in Storage | 32GB | 32GB | 32GB |
| Net Weight | 12.7g | 10.2g | 20.3g |
All three kits support 1080P/60fps resolution, 3.1-13V wide voltage input, and 500mW transmission power, delivering smooth and stunning HD footage. They are fully compatible with both Walksnail Goggles X and Goggles L. However, there are subtle but important differences between them:
Key Differences:
Mini 1S Kit comes with a Nano camera, features 14mm mounting holes for the camera and 25.5x25.5mm for the VTX.
Mini 1S Lite Kit designed as a lighter version, uses a Lite camera with no mounting holes, and shares the same 25.5x25.5mm VTX mounting as the original Mini 1S Kit. Weighing only 9.7g, it’s perfect for tinywhoops, offering an ultra-smooth flying and handling experience.
Nano Kit V3 features a native 4:3 sensor, 14mm camera mounting, and a 20mm VTX mounting pattern with M3 screws. Its metal case enhances durability, making it ideal for pilots who prefer the 4:3 aspect ratio or compete in FPV racing.
All three kits use a single-wire antenna design, ensuring minimal weight, lower cost, and broad compatibility for micro FPV drones.
| Antenna Model | 1s lite antenna | Avatar V2 antenna |
| Polarization | Linear | LHCP |
| Frequency range | 5600-5900MHz | 5600MHz-6000MHz |
| Gain | 1.6 dBi | 1.9dBi |
| VSWR | ≤1.5 | ≤1.5 |
| Size | D5mm*L70mm | D15mm*L105mm |
| Weight | 0.5g | 2g |
In Summary:
Mini 1S Lite Kit is the go-to option for ultra-light builds where every gram matters.
Nano Kit V3 and Mini 1S Kit offer better anti-interference capabilities, making them more suitable for freestyle and racing.
Choosing the right Walksnail video transmission kit depends on your specific flying needs. If you're aiming for maximum lightweight performance, the Mini 1S Lite Kit is the perfect match. For those who prioritize stronger signal performance, Nano Kit V3 and Mini 1S Kit are excellent choices. We hope this comparison helps you make the right call.
