The SIYI D6 propulsion family combines a 130KV motor with an integrated FOC controller and offers documented straight and folding propeller options. This makes the propeller version an important part of the product identity. A quotation that says only D6 can hide a meaningful difference in pitch, hardware and propeller mass.
For a civilian inspection drone or a replacement purchase, identify the version already on the aircraft and ask for the offered assembly to match it. If the buyer is comparing alternatives, list the propeller and relevant mounting parts explicitly so that the two offers describe comparable equipment.

| Catalog option | Dimensions | Material | Propeller mass |
|---|---|---|---|
| Straight propeller | 22 × 7.8 inches | Carbon fiber | 35.7g |
| Folding propeller | 22 × 9 inches | Carbon fiber | 61.2g |
The complete propulsion unit is listed at 429g excluding its propeller. Keep that figure separate from the two propeller masses. An image showing both forms is a family reference; it does not state that two propulsion units or both propeller sets are included in a single order.
The folding option may be relevant when storage space matters, while the existing aircraft configuration may determine a straight-propeller replacement. The appropriate choice still depends on the complete mounting and propeller arrangement identified by the supplier.
Confirm the arm mount or adapter included with the offered D6 revision before ordering. The catalog mentions 30mm and 25mm fit information, but a replacement purchase should identify the actual mount supplied, instead of assuming that every kit contains an adapter for both sizes.
Send the actual arm dimensions and photographs of the current assembly if available. Those details allow the supplier to distinguish a complete replacement unit from a unit that would need different mounting parts.
The ESC model is described as 55A FOC; that model designation is not a separately established continuous-current limit. The catalog recommends a 12–14S LiPo platform and states 60V as maximum working voltage. Confirm the actual battery-voltage envelope and offered revision when selecting the complete unit.
The maximum-thrust figure is 6.5kg per axis, with a catalog recommended takeoff-weight band of 2–2.5kg per axis. These numbers relate to one propulsion unit. They are not independent statements of the payload or endurance of a finished UAV.

Include the motor or assembly markings, straight or folding propeller preference, arm dimensions, power supply and intended flight-controller connection. State how many complete units and spare propellers are required. Ask the offer to name the mount, propeller hardware and cables supplied with each unit so that service replacements remain straightforward.
No. The catalog distinguishes a 22 × 7.8-inch straight propeller from a 22 × 9-inch folding propeller, with different masses.
That should be confirmed for the offered revision. The supplied description and table do not establish a universal two-size package.
No. It excludes the propeller. Use the mass of the specified propeller version and any additional mounting parts when reviewing the complete installation.
