Core Overview
The Platinum Series is committed to providing an exceptional experience for players ranging from beginners to advanced users, ensuring stable, powerful, and reliable power for your aircraft.
Core Technology Advantages
Cool Under Pressure: Patented Cooling & Flexible Fan Solutions
The V5 series (120A and above) adopts a new patented dual-sided open-heatsink structure, combined with side "window" designs to form an efficient air channel. With optional no/single/dual fan installation, you can freely balance between extreme lightweight and extreme cooling, ensuring sustained and stable power output.
Precise Man-Machine Unity: 32-bit Processor & Optimized Governor Algorithm
Equipped with a high-performance 32-bit processor and advanced algorithms, it achieves ultimate governor performance. Speed is more constant and powerful. Adjustable governor sensitivity allows control to perfectly match your personal style, offering a flight experience that matches your will.
Robust System Power: Programmable Switching BEC, Worry-Free for Complex Equipment
The entire series comes with a programmable switching BEC. For models 120A V5 and above, the BEC capability is significantly upgraded: output voltage increased to 12V (5-12V adjustable), continuous output up to 10A, with instantaneous peaks of 30A.
Intelligent Flight Manager: Full Protocol Telemetry & Easy Parameter Adjustment
The V5 series supports various telemetry protocols like Mikado VBar, Futaba S.Bus2, allowing real-time data viewing on your transmitter. Easily adjust parameters via LCD programming box or OTA wireless module, and supports firmware online updates, keeping your equipment up-to-date.
Comprehensive Safety Guardian: Anti-Spark & Multi-Protection Circuits
The V5 series has built-in anti-spark circuits, eliminating spark during power-on. The entire series features seven-fold protection: startup, over-current, over-temperature, overload, throttle signal loss, input voltage abnormal, and capacitor temperature protection, acting as a 24/7 security guard, greatly extending equipment life.
Usage Recommendations
Current Selection Core Principle: "Leave Ample Headroom" is More Important Than "Just Enough"
Common Mistake: Choosing an ESC based exactly on the motor's "maximum continuous current" rating.
Recommendation: Please reserve at least 20%-30% current headroom for the ESC. For example, if a motor has a maximum continuous current of 100A, choose a 120A or higher rated ESC.
Why? Headroom means the ESC works more easily, runs cooler, lasts longer, and has absolutely no risk of triggering over-current protection during sudden aggressive maneuvers. The ESC is the "fuse" of the power system. When it has headroom, your flight is calm and assured.
BEC Selection: Don't Just Count Servos, Consider "Simultaneous Action" Power Consumption
Common Mistake: Counting the number of servos and simply adding them up.
Recommendation: Evaluate your aircraft's "most power-hungry scenario." For example, in scale models during landing, when all control surfaces (flaps, rudder, elevator) are correcting + retracting landing gear simultaneously, that's the peak test moment for the BEC.

Frequently Asked Questions (FAQ)
Q: The 260A V5 OPTO version has no BEC. How do I power my equipment?
A: Choosing the OPTO version means you need to prepare a separate power system. Common solutions: 1) Use a high-voltage BEC module powered from the main battery; or 2) Use a dedicated 2S receiver battery directly. This version is suitable for professional scenarios that already have a mature external power supply or require extreme circuit isolation.
Q: Is the cooling fan necessary to install?
A: For models 120A V5 and above, during aggressive flying like 3D, racing, or in high ambient temperatures, it is strongly recommended to install at least a single fan. The V5 series' patented air duct design works best in conjunction with a fan to achieve optimal cooling, effectively preventing overheating protection and ensuring sustained power output. The fan is an optional accessory.
Q: There is no connector on the power wires. What should I do?
A: This is industry practice, providing maximum installation flexibility. You need to solder high-quality connectors (like XT60, XT90, EC5, AS150, etc.) of the appropriate specification according to your battery's interface. Ensure: Solder joints are solid, with no cold solder joints.
Q: Which current rating should I choose?
A: Choose based on your motor's continuous current under maximum operating conditions, and reserve at least 20%-30% current headroom for the ESC. For example, if the motor's maximum continuous current is 100A, you should choose a 120A or higher rated ESC. Sufficient headroom ensures long-term stable operation of the ESC.
