When shopping for RC boats & aircraft, the key choice is whether you need a hobby-grade motor centered on one motor configuration or a paired turbo-jet setup for building your own boat. The 3660 3680 and LK 2016 serve different project needs, so the right pick depends more on the format of your build than on a simple price comparison.
Quick verdict
Choose the 3660 3680 RC Boat Motor when the project calls for a motor-focused component with a listed hobby-grade designation and water-cooling-jacket wording. Choose the LK 2016 RC Boat Turbo JET when you want a boat part package described for making your own remote-control boat. The price spread is $21.52, but the different formats are the more useful dividing line.
At a glance
| Product | Listed price | Main format | Defining detail |
|---|---|---|---|
| 3660 3680 RC Boat Motor | USD 71.51 | Motor with water cooling jacket | Model Grade: Hobby Grade; SINGLE MOTOR |
| LK 2016 RC Boat Turbo JET | USD 49.99 | Turbo JET with motor and water cooling system X2 | RC Part; electric 4.8V-7.2V; boats under 15 inches |
Where each product wins
- 3660 3680 RC Boat Motor: The stronger match when Model Grade: Hobby Grade is the deciding attribute and the project needs a motor-centered format rather than a paired turbo-jet part.
- LK 2016 RC Boat Turbo JET: The clearer choice for a do-it-yourself remote-control boat build that specifically calls for the Turbo JET with motor format.
Product notes
3660 3680 RC Boat Motor
The 3660 3680 is a focused choice for shoppers matching a motor to an existing RC boat setup. Its description gives concrete hardware details, including a 5.00mm shaft diameter and 4mm golden banana connector, which can help narrow down whether the component suits the planned arrangement. The description also presents two motor configurations with different length, weight, voltage, and amp figures, so the exact configuration is an important limitation for anyone seeking one fixed specification. An age level of 17 Years & Up is also listed. Choose the 3660 3680 when those matching points matter more than receiving a broader boat-part package; the configuration differences deserve careful attention before selecting the component.
LK 2016 RC Boat Turbo JET
The LK 2016 is aimed at a hands-on project: its description calls it a suitable part for making your own remote-control boat and characterizes operation as light and flexible. That makes it a practical match for a builder looking for a defined boat-part format rather than a motor component alone. The listed electric range of 4.8V-7.2V is its clearest limitation because the intended setup needs to stay within that stated range. The description also identifies the part as plastic plus metal and gives a 4.5 oz weight. Choose the LK 2016 when its build-your-own-boat purpose lines up with your project and the electrical specification works for the setup.
Final choice by use case
- For matching a motor to an existing build: Choose the 3660 3680, since its 5.00mm shaft and 4mm connectors provide specific hardware points to align.
- For a do-it-yourself boat using the under-15-inch direction: Choose the LK 2016, whose description directly identifies that boat-use context.
- For the lower listed price: Choose the LK 2016 at USD 49.99; the 3660 3680 is listed at USD 71.51.
The simplest decision is therefore format-first: the 3660 3680 suits a motor-centered project, while the LK 2016 is the more direct match for the stated Turbo JET boat-part use.
