Preguntas Frecuentes (FAQ)

Q: What is the main advantage of the JHE42B/JHE42B-s Finder over a traditional FPV buzzer and how does the search function work in case of signal loss?
A: The main advantage is its ability to emit a 110dB sound and white LED light even after the drone's main battery is depleted. After 30 seconds without power from the main battery, the buzzer activates automatically, making it easier to locate the drone even if the connection with the flight controller is lost. This is especially useful in areas with dense vegetation or in low-visibility conditions.

Q: How is the JHE42B/JHE42B-s Finder connected to my flight controller and which flight controllers are compatible? Do I need to do any additional setup in Betaflight or Cleanflight?
A: The Finder connects directly to the flight controller's buzzer interface using the included 3P*1.0MM cable. It is compatible with all Betaflight (BF) and Cleanflight (CF) flight controllers. It generally requires no additional setup; once connected and with the drone powered on, the flight controller will power it (indicated by the red charging LED). However, you may need to check the buzzer setting in your firmware to make sure it is enabled.

Q: What is the difference between the JHE42B and the JHE42B-s Finder in terms of size, weight and potentially performance? Which would you recommend for a 5-inch racing drone?
A: The JHE42B Finder measures 23x17x17mm and weighs 7.4g, while the JHE42B-s Finder is more compact, at 18x17x15mm and 4.3g. Both models offer the same 110dB sound function and automatic activation in case of battery failure. For a 5-inch racing drone, the JHE42B-s Finder is generally preferable because of its lower weight, which can contribute to better performance and flight time. However, if space is not a constraint, the JHE42B will also work properly.
