1Hull concepton
After analyzing the DXF, here’s a breakdown of typical parts (exact shapes may vary slightly):
Part Description Base Keel Plate Long central piece forming the spine of the hull Bulkheads / Ribs Vertical cross-sections with slots, numbered front to back Side Panels (2x) Long side shapes forming the hull's sides Deck Plate Top cover plate (flat or partially open) Transom Back end plate of the hull Bow Piece Front end plate of the hull Note: Some designs combine bow & deck or use symmetry for mirrored parts.
🧩 2. Pre-Assembly Tips
-
Material: Typically 3 mm plywood or acrylic
-
Kerf Compensation: If your cutter removes ~0.15 mm per cut, your slots should be slightly narrower
-
Label Each Part: Lightly engrave or mark each part with a pencil before removing them from the board
🪚 3. Assembly Steps
🔹 Step 1: Prepare the Keel
-
Lay the base keel plate flat on your workbench.
-
Make sure all slot cuts are clean (you can sand if needed).
🔹 Step 2: Insert Bulkheads
-
Starting from the bow (front), insert each bulkhead into the matching slot on the keel.
-
The tabs should fit snugly. Use light pressure.
-
Ensure all bulkheads are perpendicular to the keel.
🔹 Step 3: Attach Side Panels
-
Slot the left and right hull side panels into the notches on each bulkhead.
-
This will shape the hull.
-
Use rubber bands or clamps to hold parts together temporarily.
🔹 Step 4: Install the Transom and Bow
-
Insert the transom (rear plate) and bow (front) between the two side panels.
-
These should lock into the side panels and bottom keel.
🔹 Step 5: Add the Deck Plate
-
Once the internal frame is solid, place the deck over the top.
-
Make sure it matches the outer edges and locks with the bulkheads.
💧 4. Waterproofing & Sealing
-
Use wood glue for assembly, followed by a marine-grade sealant or epoxy resin.
-
Sand lightly before sealing for better adhesion.
-
For electronics, consider building a removable waterproof hatch.
🛠️ 5. Finishing Touches
-
Sand sharp edges and corners.
-
Paint with waterproof or marine-safe paint.
-
Test float before installing electronics or motor.
Would you like me to:
-
Annotate or label the parts visually in the DXF?
-
Generate a 3D mockup or assembly image?

2motor assembly
✅ 1. Connect the ESC to the Brushed DC Motor
-
Red wire from ESC → Motor terminal 1
-
Black wire from ESC → Motor terminal 2
(If the motor spins in reverse, swap these later.)
✅ 2. Connect the Battery to the ESC
-
ESC's red (thick) → Battery +
-
ESC's black (thick) → Battery –
⚠️ Ensure connectors match (JST, XT60, etc.). Never reverse polarity.
✅ 3. Connect ESC to Receiver
-
Plug the ESC’s 3-pin servo-style connector into Channel 2 (for throttle) on the receiver.
-
Match wire orientation: Signal (white/yellow), Vcc (red), GND (black)
-
✅ 4. Connect the Two Servos to the Receiver
-
Servo 1 → Channel 1 (steering, or other control)
-
Servo 2 → Channel 3 or 4
-
Again, match polarity: GND (brown/black), Vcc (red), Signal (orange/yellow)
✅ 5. Powering the Receiver (ESC with BEC)
-
Your ESC most likely has a built-in BEC, which provides 5V to power the receiver through the same 3-pin cable.
-
You do not need extra wiring for receiver power.
✅ 6. Power Up and Bind Receiver
-
Turn ON your transmitter first.
-
Then connect the LiPo to the ESC.
-
The receiver should light up and bind automatically, or follow your system’s bind procedure.
✅ 7. Test
-
Use transmitter sticks to:
-
Control motor throttle (Channel 2)
-
Move servos (Channels 1, 3, or 4)
