Vintage Shovelnose Hydroplane RC Boat Hull Kit – 28\", 34\" & 39\" For Sale

Vintage-style shovelnose RC hydroplane hull available in 28\", 34\", and 39\" sizes.

Each hull is 3D printed in white PETG and comes as a 7-piece unassembled kit. The three sizes were laid out around the general size range of N, P, and Q fast-electric sport hydro setups.

This listing is for the unfinished printed hull only. It will need to be assembled, reinforced, finished, and rigged with your own electronics and running hardware.

• Length: 28\" / approximately 711mm

• Width: approximately 15.4\"

• 7-piece hull kit

• Smaller lightweight option

• Good starting size for an N-style fast-electric setup

• Length: 34\" / 864mm

• Width: approximately 17.4\" / 441mm

• 7-piece hull kit

• More room for batteries and electronics

• Good starting size for a P-style fast-electric setup

• Length: 39\" / 991mm

• Width: approximately 19.9\" / 506mm

• 7-piece hull kit

• Larger hull with more room for heavier-duty running hardware

• Good starting size for a Q-style fast-electric setup

Each hull is printed in white PETG.

PETG works well for these hulls because it has a little more give than PLA while still being easy to sand, epoxy, reinforce, prime, and paint.

Like any unfinished 3D printed hull, normal layer lines, section seams, and minor surface imperfections should be expected.

The hull can be left fairly simple for a basic running setup or fully sanded, filled, primed, and painted for a smoother finished appearance.

The exact setup will depend on the hull size, finished weight, battery voltage, motor KV, and the speed you are looking for.

These are good starting points.

• 36mm brushless inrunner

• 80A–100A water-cooled marine ESC

• 2S–4S LiPo depending on motor KV

• 20kg+ waterproof steering servo

• 3/16\" flex shaft

• Adjustable hydro strut

• Approximately 36–42mm propeller

• 3660 or 3674 brushless motor

• 100A–150A water-cooled marine ESC

• 3S–4S LiPo

• 20kg+ waterproof steering servo

• 3/16\" flex shaft

• Adjustable hydro strut

• Approximately 38–42mm propeller

• 4074-size brushless motor

• 150A+ water-cooled marine ESC

• 5S–6S LiPo

• High-torque waterproof steering servo

• Heavy-duty 3/16\" flex shaft

• Adjustable strut and rudder

• Propeller matched to your motor KV and battery voltage

These are starting recommendations only.

Hydroplanes can be very sensitive to prop size, strut height, CG, finished weight, and battery placement. I recommend starting with a conservative prop and checking motor, ESC, battery, wiring, and connector temperatures as you tune the boat.

The hull comes in 7 separate printed sections and requires assembly.

For assembly, I recommend lightly sanding the mating surfaces and getting all of the sections lined up before permanently bonding anything.

I’ve had good results using a few small drops of CA glue to hold the sections in position and then reinforcing the main joints with two-part epoxy.

Make sure the hull is straight and square before the adhesive fully cures.

For higher-power setups, fiberglass or carbon fiber cloth with epoxy is strongly recommended, especially on the larger 34\" and 39\" hulls.

I warranty my printed parts against manufacturing defects in the material or printing process at the time of purchase.

This does not cover damage caused by crashes, impacts, improper assembly, incorrect bonding or reinforcement, water intrusion, incorrect electronics, overheating, oversized props, excessive power, improper setup, or normal wear and tear.

Normal characteristics of 3D printing such as layer lines, section seams, and minor surface variations are not considered defects unless they affect the strength or intended use of the part.

Sanding, drilling, painting, or reinforcing the hull does not automatically void the warranty. However, damage caused by those modifications is not covered.

If there is a legitimate manufacturing defect, I’ll work with you on an appropriate solution. Depending on the issue, this may include repair, a replacement section, replacement component, store credit, or another agreed solution.

Proof of purchase is required, and I may ask for photos, video, or return of the affected part so I can determine what happened.

These hulls are sold as unfinished DIY kits unless otherwise stated.

The final strength of the boat depends heavily on how it is assembled, bonded, reinforced, and rigged.

For higher-powered builds, I strongly recommend reinforcing the hull with epoxy, fiberglass, carbon fiber, or a combination of these materials.

I cannot guarantee a specific speed, runtime, handling characteristic, or maximum safe power level because every boat is assembled and set up differently.

Any electronics or prop recommendations in my listings are starting points based on the size and intended setup of the hull.

Battery voltage, prop size and pitch, motor load, cooling, finished weight, and CG all need to work together.

When testing a new setup, start conservatively and check motor, ESC, battery, wiring, and connector temperatures.

Damage caused by an incorrectly selected or configured power system is not considered a manufacturing defect.

Things happen with RC boats.

If you damage part of the hull in a crash or another situation that isn\'t covered by warranty, replacement printed sections may be available for purchase.

Send me a few clear pictures through Messages and I can usually determine which section you need.

For warranty questions, contact me through Messages before returning anything.

Please include your order number, a description of the problem, and clear pictures or video when applicable.

Any returns will be handled based on the individual situation and applicable policies.

Always inspect the hull, rudder, strut, prop, steering linkage, fasteners, batteries, wiring, and electronics before running the boat.

Keep high-performance RC boats away from swimmers, animals, docks, shorelines, and full-size boats.

The builder/operator is responsible for proper assembly, setup, maintenance, and safe operation.

This limited warranty is governed by the laws of the State of New York, except where federal law or other applicable consumer protections apply. Nothing in this warranty is intended to limit rights that cannot legally be waived.
