Model Features:
1. Compact size and simple assembly. With a length of no more than 30 cm, it can be easily held in one hand. The model consists of only two parts, all components are pre‑mounted on a single build plate, allowing for direct printing from the plate. Printing takes less than 9 hours and requires approximately 230 g of PLA wood filament.
2. Optimized center of gravity for smooth sailing. By carefully controlling material density at different heights within the hull, buoyancy is maintained, the center of gravity is optimized, and structural strength is enhanced, effectively lowering the vessel’s overall center of gravity.
3. Ingenious design with triple waterproofing. The engine compartment features a modular layout, divided into separate drive‑shaft and battery sections. Even if a small amount of water enters the drive‑shaft compartment, it will not leak into the main cabin or the battery compartment. The external hatch is styled to resemble a traditional Chinese painted boat, seamlessly concealing all electronic components while protecting them from splashing water.
 

Assembly Instructions:
1. First, attach the two motors to the silicone tubes and drive shafts (no metal sleeves are required for the drive shafts). Place the motors into their motor mounts, then insert the drive shafts through the hull and secure them at the rear.
2. Install the two propellers, ensuring correct left/right orientation, and adjust the lengths of the silicone tubes and drive shafts to guarantee smooth operation of all mechanical components.
3. Secure both motors to the base using double‑sided tape, connect the control panel and battery, and place these components in the front battery compartment. Route and neatly organize the wiring, then close the hatch. (Although many RC components are available on the market, this model essentially comprises just these few parts, making assembly relatively straightforward.)

Special Note: This dragon boat is not an RC speedboat; its center of gravity is higher. When operating remotely, avoid full throttle, abrupt acceleration, and sharp turns to prevent capsizing.
