7-Inch to 15-Inch FPV Drones: Matching Size to Payload
zhanghaowen
Choosing an FPV drone by propeller size alone can make it harder to compare models. A more practical starting point is the payload you need to carry and whether that load falls within a model’s published range.
QINKO FPV currently lists four platforms with different payload classes:
| Model | Listed payload range |
|---|---|
| 7-inch FPV drone | 1.5–2 kg |
| 10-inch FPV drone | 3–4 kg |
| 13-inch FPV drone | 6–8 kg |
| 15-inch FPV drone | 8–10 kg |
What the payload ranges tell you
These figures are useful for narrowing down the product range, but they do not automatically confirm that every load within a range is suitable for every configuration. The payload’s shape, size, and mounting arrangement can affect whether it fits the aircraft and how the finished setup performs.
For a task-specific or single-deployment setup, start with the item you plan to carry. Include its enclosure and any separate equipment that will fly with it. Then ask the supplier to confirm how the published payload figure is defined for the exact configuration.
Do not guess between listed ranges
The published ranges leave gaps. For example, a 2.5 kg load is not covered by the listed 7-inch or 10-inch ranges, and a 5 kg load is not covered by the listed 10-inch or 13-inch ranges. Do not assume that the nearest larger model is automatically the right fit; request confirmation for the complete load and aircraft configuration.
There is also a boundary at 8 kg: it appears at the upper end of the 13-inch range and the lower end of the 15-inch range. When a load is near a boundary, compare the full setup with the supplier instead of choosing by the number alone.
A practical way to choose
- Write down the weight and dimensions of the complete carried load.
- Compare that figure with the model’s listed payload range.
- Check that the load’s shape and mounting arrangement suit the aircraft.
- Ask the supplier to confirm the recommended model for your exact configuration, especially if the load falls between published ranges.
The payload range is a starting point for comparing the 7-, 10-, 13-, and 15-inch platforms. Matching the complete load to a confirmed configuration helps make the model choice clearer before ordering.
