Unleash Your RC Gear: YoungRC 20A Electronic Switch Relay Review

For RC enthusiasts looking to enhance control over their drones, cars, trucks, boats, or LED light setups, the YoungRC Remote Controlled AUX on/Off 3~30V High Current RC 20A Electronic Switch Relay offers an intriguing solution. Designed to provide remote-controlled switching capabilities via PWM signals, this compact relay aims to add ease and versatility to your RC projects. In this review, we’ll explore its features, advantages, and potential drawbacks to help you decide if it fits your needs.

Key Features

The YoungRC 20A Electronic Switch Relay stands out with several notable specifications that cater specifically to hobbyists seeking reliable power switching controlled remotely:

• Wide Operating Voltage Range: Available in versions supporting 3.0V to 5V (low voltage) and 3.0V to 30V (high voltage), this relay offers flexibility for various RC setups. The high voltage version can safely handle devices requiring up to 30V, broadening its application.
• High Output Current Capacity of 20A: This feature makes it capable of driving high-current loads such as motors, LED arrays, or other auxiliary equipment without overheating or failure, which is essential for demanding RC vehicles or boats.
• PWM Signal Control with a Two-Level Switch: The relay is controlled through a simple two-level remote switch, making it straightforward to turn devices on or off from your RC transmitter. A PWM pulse width of less than 1.5ms turns the relay off, while anything above 1.5ms turns it on, providing responsive control.
• LED Status Indicators: The relay includes working lights that help users monitor the output status easily. Slow LED flashing signals no output, while long LED flashing indicates active output, simplifying troubleshooting and operation during use.
• Lightweight and Compact: Weighing only 5g, this small-sized component won’t add significant bulk or weight to your RC models, which is crucial for maintaining performance and balance.
• Package Includes Two Units: At a price point of about $16, receiving two relays provides good value, especially for multi-device control or backup purposes.

Pros & Cons

Pros

• Reliable Switching Performance: Many users appreciate the solid power handling and consistent control response, particularly for LED lights and auxiliary devices on RC drones and cars.
• Compact Size and Ease of Integration: The small form factor and clear LED indications make installation and status checking convenient.
• Good Value for Cost: Getting two relays in one package at a moderate price makes this a budget-friendly option to experiment with or expand your RC control capabilities.

Cons

• Limited User Feedback and Variation in Experience: Some reviews point to occasional issues such as difficulty in setup due to limited instructions, or inconsistent operation if PWM signals are marginal or poorly calibrated.
• Average Build Quality: A few users have noted that while functional, the relay’s construction feels basic and might require careful handling to avoid damage.
• 3.9 out of 5 Stars Rating: Although close to a good rating, a number of critical opinions suggest it may not be ideal for all environments or users looking for high-end electronic components.

Who Is It For?

The YoungRC 20A Electronic Switch Relay is ideal for hobbyists and DIY enthusiasts who want to add remote on/off control to their RC cars, drones, boats, or any auxiliary devices like LED lights with moderate power demands. It suits those comfortable with basic electrical integration and who need a compact, cost-effective relay capable of handling currents up to 20 amps. Beginners willing to learn PWM control and who prefer affordable experimentation will also find this relay useful.
