Core Overview: Hobbywing X13 Power System
Engineered exclusively for extreme-payload multicopters and industrial-grade UAV platforms, the Hobbywing X13 Multi-rotor Drone Power System Kit establishes a new paradigm in heavy-lift aerial propulsion. Generating a monumental maximum thrust of 57kg per axis, this integrated motor, ESC, and propeller architecture is mathematically optimized for platforms with a takeoff weight of 25-27kg per rotor. Available in distinct 14S and 18S voltage variants, the X13 leverages a massive 138x25mm stator combined with highly rigid 56-inch carbon polymer folding blades to deliver relentless electro-mechanical efficiency. Designed for absolute structural integrity and sustained operation under punishing environmental conditions, the X13 ensures maximum up-time for heavy cargo logistics, large-scale agricultural spraying, and high-stakes enterprise drone operations.
Key Technological Advancements
- ■ Extreme Heavy-Lift Capacity: Pushing the boundaries of payload limits, the X13 generates up to 57kg of peak thrust per axis. It is the definitive heavy-lift drone power system for enterprise hexacopters and quadcopters demanding maximum cargo capabilities.
- ■ Dual Architecture Integration (14S/18S): Tailor your power grid with high-voltage 14S (54V) or ultra-high-voltage 18S (70V) configurations. Operating at 18S minimizes current draw (I²R losses) and thermal load, drastically optimizing battery endurance for specialized agricultural drone motors.
- ■ IPX6 Industrial Ingress Protection: Fully sealed waterproof bearings and encapsulated ESC boards guarantee this multirotor propulsion system can operate flawlessly in torrential rain or highly corrosive chemical spraying environments.
- ■ Modular 50mm Tube Mounting: Features a standardized, quick-detach 50mm outer diameter clamping system. Waterproof connectors enable the ESC to be removed or installed in about one minute, slashing field maintenance downtime.
Engineer's Pro Tip: High-Voltage Bus & Structural Tolerance
When implementing the 18S (70V) variant, standard anti-spark connectors (like AS150) are mandatory, as the inrush current to the massive ESC capacitors will arc heavily on standard terminals. Because a single motor can generate 57kg of thrust and massive torque from the 56-inch props, your frame's 50mm carbon tubes must feature a wall thickness of at least 2.5mm to 3.0mm; anything thinner risks catastrophic torsional failure or delamination during aggressive yaw inputs.

Engineering FAQ
Q1: How should I choose between the 14S and 18S architecture for my enterprise build?
A: The 18S variant operates at a higher voltage (70V max vs 54V max), scaling down the motor KV to 45 rpm/V from 60 rpm/V. If your drone is designed for extremely long endurance flights or operates consistently near its maximum payload, the 18S system will drastically reduce line current (Amps), minimizing heat generation across your ESCs and PDB, thereby extending overall powertrain reliability.
Q2: Does the X13 power system support CAN bus communication natively?
A: The standard control protocol for this architecture is a high-frequency PWM throttle signal (50-500Hz, 1050-1950us pulse width) which natively supports 3.3V and 5V logic levels from flight controllers like Pixhawk, Cube, or DJI A3. It relies on standard PWM rather than CAN bus for direct motor commutation.
Q3: Is active cooling required for the ESC, given the 200A peak current rating?
A: No. The ESC is structurally integrated beneath the motor mount specifically to utilize the immense downdraft generated by the 56-inch propellers. Active external cooling is unnecessary as long as the ambient temperature remains below 60℃ and the ESC housing is not obstructed by custom canopies.
Q4: What are the exact structural requirements for mounting the drone arms?
A: The X13 motor mount is precision-machined for 50mm outer diameter carbon fiber arm tubes. You must ensure your tubes have tight manufacturing tolerances so the clamp achieves full, even surface contact. A loose fit or point-loading can lead to catastrophic harmonic vibrations given the massive 57kg peak thrust potential.

11、Answer: Typically required documents:
- ID (e.g., passport) or business tax number;
- Commercial invoice (contact us after purchase);
- Tip: Contact your local customs in advance!
12、Answer: Duties are determined by your country’s customs based on product type, value, and regulations. To estimate costs:
- Check your local customs website;
- Use third-party tools (e.g., Avalara, DutyCalculator).
13、Answer:
- Delays: Contact customs directly to submit documents/payments. We can provide tracking numbers or invoices.
- Destruction: Losses due to unresponsive clearance will be borne by the customer.
- Exceptions: If caused by our documentation errors, contact us for support.
14、Answer: You will receive a commercial invoice and packing list via email. For other documents, contact sales@uavmodel.com (response within 24 hours).
15、Answer: The following products may be seized or rejected:
- Prohibited items in your country (e.g., cosmetics with banned ingredients);
- Products without required certifications (e.g., electronics lacking CE marks);
- Under-declared value (may raise tax evasion suspicions).
If you pay by credit card, your payment could be somehow denied at the checkout by our system in defense against possible credit card fraud. It's a good idea to call your credit card company or bank ahead of time to let them know about the purchase so that it doesn't get declined.
Under such circumstance, here are 3 solutions for you:
1. If you have a PayPal account, please try to pay by PayPal.
2. Please switch to your other credit/debit cards.
3. If you do not have a PayPal account, please select PayPal still at the checkout page & click the complete order button. Then you'll be directed to a page with access to both PayPal and Debit/Credit card payment (for the latter option, you don't have to register for PayPal).
As following steps:
Step 1. Select PayPal (even if you don't have a PayPal account)

Step 2. Click on "Pay with Debit or Credit Card".

Step 3. Fill in your credit card info and complete your order.
