Frequently Asked Questions

• Is the Etronix Pulse FHSS Receiver compatible with other Etronix transmitters? — No, this receiver (ET1166) is specifically designed for use with the Etronix ET1109 EX4S transmitter. If you own a different Etronix transmitter model such as the ET1111, you will need a different receiver (such as the ET1165). Always verify transmitter and receiver compatibility before purchasing to ensure your radio system components work together correctly.
• What does FHSS mean and why does it matter for RC cars? — FHSS stands for Frequency-Hopping Spread Spectrum. This technology makes your RC radio system more secure and resistant to interference by constantly switching between different frequencies within the 2.4GHz band. This is particularly useful if you're racing or operating your RC car at a UK club event where multiple radio systems are in use simultaneously, as FHSS helps prevent one system from interfering with another.
• How small is this receiver and will it fit in my RC car? — The receiver measures 31mm in length, 20mm in width and 13mm in height, making it one of the more compact receiver options available. This compact size means it will fit into most RC car chassis designs without requiring major modifications, though you should still check your specific model's available space before ordering.
• Is this a suitable receiver for beginners? — Yes, the Etronix Pulse FHSS receiver is straightforward to install and use, making it suitable for hobbyists new to RC cars. If you already own an Etronix EX4S transmitter system, simply plugging in this receiver (after proper binding procedures) will get your model up and running without complicated setup requirements.
• Can I use this receiver with the EX4G transmitter? — No, this receiver is not compatible with the EX4G transmitter. If you need a receiver for an EX4G system, you will require a different model (ET1154). Always check your transmitter model before ordering a replacement or spare receiver.
• What frequency does this receiver operate on? — This receiver operates on the 2.4GHz frequency band, which is the modern standard for RC hobby use across the UK and internationally. The 2.4GHz band offers excellent range, interference resistance through FHSS technology, and is the frequency band used by the vast majority of contemporary RC radio systems.
