Frequently Asked Questions:

Q1. What is the main advantage of ExpressLRS (ELRS) over other radio systems?

Ans. The main advantages of ELRS are its exceptional long-range capability combined with very low latency. This allows for a more responsive and reliable control link, which is crucial for precision flying, FPV racing, and long-distance flights where signal integrity is paramount.

Q2. Is this TX module compatible with my existing radio transmitter?

Ans. This module is designed to be compatible with any radio transmitter that has a standard JR module bay. Most popular radios from brands like FrSky, Jumper, RadioMaster, and others are compatible. It's recommended to check your radio's manual to confirm it has a JR bay.

Q3. What is the purpose of the adjustable power output?

Ans. Adjustable power output allows you to optimize performance for different flight scenarios. Lower power (e.g., 100mW) is sufficient for close-range flying and conserves battery. Higher power (e.g., 500mW+) is used for long-range flights or flying in environments with signal interference to maintain a strong, reliable link.
