Drone Rack Frames and Accessories: A Guide to the Range
A drone frame connects the main parts of an aircraft, while its accessories help define the final assembly. The YJTech Drones Drone rack collection brings together eight product entries, from traversing frames and FPV frame accessories to agricultural UAV frames, structural accessories and a centrifugal nozzle. Understanding the role of each entry is a useful first step toward preparing a clear enquiry.
The agricultural models span 10L, 16L, 30L and 50L designations. They differ in their listed configuration and in the level of technical information available. The guide below explains the confirmed details of each product and the questions to resolve before ordering. Each image and product link opens the corresponding detail page, where the independent gallery and product information can be reviewed.
Traversing frame

The Traversing frame is the starting point of the FPV frame selection in this range. Its listed project name is RC-APEX-7, its model designation is Mark 4 7inch, and its place of origin is Shandong, China. These identifiers make it easier to distinguish this frame from the larger agricultural UAV structures featured later in the collection.
When planning an assembly or replacement, use the model designation together with the product photographs. A familiar frame name alone does not confirm every mounting dimension or component combination. Share the motor, propeller, flight controller and other components you intend to use so the required frame configuration can be checked before ordering.

Traversing machine frame accessories

The Traversing machine frame accessories entry covers the Mark 4 V2 designation in 8, 9 and 10 inch sizes. The product information lists Shandong, China as the place of origin and indicates that a private mold is not provided. This makes size and model identification the main starting points when comparing the available frame options.
For an existing build, first identify the size already in use and compare the required parts with the product images. For a new project, provide the planned component layout and the accessories you require. Confirming the exact configuration helps avoid treating different frame sizes as interchangeable simply because they belong to the same product range.

Four-axis 10L plant protection UAV

The four-axis 10L plant protection UAV frame is identified as the YJTech Y610. It is listed as a drone accessory for agricultural spraying and fertilizing, with an integrated body intended to provide a durable structural base. Its design separates signal and power routing to help reduce interference within the assembled system.
The surface has a UV treatment and is described as corrosion resistant and waterproof. These frame features are relevant when comparing agricultural equipment that will be used around spray liquids and outdoor conditions. The frame listing should still be checked against the complete assembly you need: confirm which propulsion components, control equipment and spraying parts are included in the quotation.

Six-axis 16L plant protection UAV

The YJTech Y616 is the six-axis 16L model in the collection. Its published dimensions provide a useful basis for assessing storage and transport: the wheelbase is 1628mm, the expanded size is 1720 × 1500 × 556mm, and the folded size is 1073 × 956 × 546mm. The listed rack weight is 7kg, excluding the sprinkler system, and the medicine tank capacity is 16L.
Its integrated waterproof body is washable. Injection-molded folding components and C-type arm clamps support stable connections, while a concealed distributor separates power and signal paths. Compare both the folded and expanded dimensions with your transport arrangements, then confirm the final assembled weight and equipment configuration separately from the bare frame figures.

Six-axis 30L plant protection UAV

The six-axis 30L plant protection UAV frame is the YJTech Y630. It combines an integrated body with a cross-level folding structure and offers AS150U or MOLEX battery interface options. Its dustproof and waterproof construction is described as washable, and the product information includes switching between spraying and spreading applications.
The shared four-axis and six-axis frame platform supports 20L to 30L configurations. This platform information does not mean that every option is supplied with every order. Specify the six-axis version, tank capacity, battery interface and intended spraying or spreading arrangement when requesting a quotation. Those details help define the actual configuration being compared.

Four-axis 50L plant protection UAV

The four-axis 50L plant protection UAV is identified as the YJTech Y650 and is listed as a drone accessory for spraying and fertilizing. It adds a 50L frame option to a range that also contains the Y610, Y616 and Y630 models. The product images provide a visual reference for its body, arms and overall configuration.
Tank capacity is only one part of choosing an agricultural UAV assembly. The available listing does not provide a complete set of dimensions, weights or flight-performance figures for this model. Ask for the current configuration details and included components before comparing it with a finished aircraft or planning your transport and assembly requirements.

Plant protection machine frame accessories

Plant protection machine frame accessories support the structural side of an agricultural UAV build. This product entry describes integrated carbon-fiber molding, a rigid structure that helps reduce vibration, and a stable connection that helps maintain the horizontal position. These characteristics distinguish it from the complete frame models and from spray-system accessories.
When replacing a structural component, identify the existing frame and provide clear photographs of the connection and mounting position. Ask for confirmation of the matching part and dimensions rather than relying only on a similar appearance. This is particularly useful where an agricultural frame has been assembled with components from different configurations or has changed during earlier maintenance.

Centrifugal nozzle

The Centrifugal nozzle is included as a separate accessory in the Drone rack collection. Its product page offers images for identification and a direct route to enquire about the configuration required for a spraying system. It should be considered separately from the frame structure and tank capacity when preparing a component list.
The available information does not establish a verified flow rate, operating pressure, spray width or droplet-size range for this item. When enquiring, provide the spraying system model, connection details and the component you need to replace or add. YJTech Drones can then be asked to confirm the appropriate specification and compatibility for the proposed assembly.

Choosing the Right Frame and Accessories
Start with the intended application and the exact model you are comparing. FPV frame sizes, agricultural tank capacities and structural accessory descriptions refer to different aspects of a build. A larger tank designation does not, by itself, establish flight time, working coverage or the payload of a completed aircraft. Those figures depend on the final system and should be confirmed for the specific configuration.
Next, separate the frame specifications from the equipment supplied with it. Check the battery connection, mounting requirements, folding dimensions where available, and the spraying or spreading components needed for the project. For replacement parts, photographs of the existing assembly and the original model number are useful references. For a new build, a component list helps make the enquiry more precise.
Discuss Your Configuration with YJTech Drones
To request a quotation, include the product name, selected size or capacity, intended application, required quantity and the parts you expect to receive. If you are replacing an existing component, add the frame model and connection details. Use the enquiry form on this page or contact YJTech Drones to confirm compatibility, current specifications, availability and the scope of supply.
