Key Applications and Projects

• Flying Wings / Delta Wings: Providing the screaming high pitch-speed required to push foam-board or EPP flying wings to their absolute structural limits.

• Park Jets (Pusher Configuration): Ideal for mounting on the rear of foam fighter jet profiles (like the F-22 or Su-27 park flyers).

• High-Speed RC Airboats: Powering DIY surface vehicles where the extreme-RPM motor acts as a massive ducted fan to push the hull at blistering speeds across smooth water.

Unlock New Capabilities (Project Evolution)

• The 100+ mph Speed Wing: Because this 2450KV motor spins so fast, it pulls a massive amount of current. Evolve your standard foamie airplane by pairing this motor with a heavy-duty 40A ESC and an aerodynamic Carbon Fiber 5x5 Propeller. By reinforcing your airplane's wings with carbon fiber spars and covering the foam in laminating film to handle the immense aerodynamic stress, this motor will easily push a lightweight airframe past 100mph!

Package Includes:

• 1 x A2212 KV2450 Brushless Motor (with pre-soldered 3.5mm banana plugs)

• 1 x Aluminum X-Mount Bracket

• 1 x Collet-Style Propeller Adapter

• 4 x Countersunk Mounting Screws

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What does "KV2450" mean? KV stands for "Velocity Constant." It means the motor is engineered to spin at an incredibly fast 2450 RPM for every 1 volt of electricity applied to it when unloaded.

2. Can I use a 10-inch propeller (like a 1045) on this motor? ABSOLUTELY NOT. Because the 2450KV motor spins so fast, attaching a large 10-inch propeller will cause it to pull massive amounts of current, instantly burning out the motor and your ESC. You must use small 5-inch or 6-inch props.

3. Is this motor brushed or brushless? This is a 3-phase brushless outrunner motor. It requires no maintenance brushes and operates with incredible efficiency.

4. What are the gold connectors attached to the wires? They are factory pre-welded 3.5mm male banana plugs (often called bullet connectors).

5. Do I need to solder anything to use this motor? No! Because the 3.5mm connectors are already installed and wrapped in heat shrink, you can plug them directly into an ESC that has matching female 3.5mm plugs.

6. What size Electronic Speed Controller (ESC) do I need? Because the 2450KV motor pulls significantly more current than lower KV versions, a robust 40A brushless ESC is highly recommended to prevent your electronics from catching fire.

7. Can I connect this motor directly to a battery? No. Brushless motors require an Electronic Speed Controller (ESC) to turn the DC battery power into 3-phase AC power. Connecting it directly to a battery will instantly fry the copper coils.

8. What is the cross-shaped metal piece used for? That is the aluminum X-mount. It provides a wider, stable 4-hole mounting footprint for bolting the motor securely to an airplane firewall.

9. What are the four small screws for? They are countersunk machine screws used to bolt the aluminum X-mount tightly to the threaded holes on the bottom of the golden motor casing.

10. What is the silver bullet-shaped part? That is a collet-style propeller adapter. It grips the bare motor shaft and provides a threaded post and washer to securely lock down your propeller.

11. What size battery should I use? This motor is optimized for 3S (11.1V) LiPo batteries. Ensure your battery has a high "C-rating" (e.g., 40C or higher) to handle the rapid current draw.

12. What size propeller is best for the 2450KV version? A 5-inch prop (like a 5030, 5x5, or 6x4E at maximum) is ideal for a 3S setup to keep the motor within safe operating temperatures.

13. How do I reverse the direction the motor spins? Simply unplug any two of the three banana plug wires connecting the motor to the ESC, and swap them. This reverses the electrical phasing and changes the rotation direction instantly.

14. Does "Four Axis" mean I have to use it on a quadcopter? "Four Axis" translates to quadcopter. While you could put these on a very small, aggressive racing drone, 2450KV motors are overwhelmingly preferred for single-motor fixed-wing RC airplanes and pusher jets.

15. What does "A2212" mean? It is an industry-standard size class, referring to the internal dimensions of the motor (22mm stator diameter, 12mm stator height).

16. Is a propeller included in this package? No, the package only includes the motor, the X-mount, the mounting screws, and the collet prop adapter.

17. Is this motor waterproof? No. The copper coils inside the housing are entirely exposed to allow for crucial air cooling. Submerging the motor while it has power will cause an immediate electrical short.

18. How does the prop adapter stay on the smooth motor shaft? It utilizes a compression collet design. The base of the adapter is slotted; as you tighten the top nut down onto your propeller, it forces the slotted base to squeeze incredibly tightly onto the smooth motor shaft.

19. Why are there three wires? Brushless motors operate using 3-phase power dynamically generated by the ESC. The three wires sequence power to the electromagnets inside the bell to create a spinning magnetic field.

20. Can I use this 2450KV motor to power an RC car? It is heavily discouraged. Outrunner motors are designed for aircraft where they receive constant, massive cooling airflow from a propeller. Using it inside an enclosed RC car chassis will quickly cause it to overheat and melt the stator windings.
