Frequently Asked Questions

Q: Is the Flysky FS-GT3B compatible with all RC cars and boats?

A: The Flysky FS-GT3B is compatible with most RC cars and boats that use standard PWM servo connections. It works in "car/boat" mode and supports any ESC or servo operating on a 4.0–6.5V DC supply. Always check your vehicle's receiver requirements before purchasing.

Q: Do I need to buy batteries separately for the FS-GT3B transmitter?

A: Yes. The FS-GT3B transmitter requires 8×AA 1.5V batteries (totaling 12V), which are NOT included in the package. The receiver is powered by your vehicle's ESC/BEC (4.0–6.5V DC) and does not need separate batteries.

Q: What does AFHDS mean and why does it matter?

A: AFHDS stands for Automatic Frequency Hopping Digital System. It automatically scans and hops across 160 frequency bands in the 2.4GHz range, which virtually eliminates radio interference from other RC controllers or wireless devices nearby — giving you a more stable and reliable control signal.

Q: Can I use the FS-GT3B with a PC flight simulator?

A: Yes! The transmitter features a 3.5mm DSC port that outputs a PPM signal, allowing you to connect it directly to a PC and use it with RC simulator software for practice — without needing a vehicle or receiver bound.
