4-Channel 2.4GHz RC Transmitter

The DUMBORC X4 is a 4-channel 2.4 GHz radio transmitter designed for RC cars, boats and tanks. It pairs with the included X6F receiver and offers mixed-mode control on channels one and two for custom steering or throttle setups. Channels three and four can drive accessories such as lights or a winch when an extra switch board is fitted. The throttle speed limit function helps beginners and younger drivers practise at reduced speeds.

Practical limits of the 2.4GHz FHSS link

The pseudo-random FHSS algorithm provides a stated control range of 1640 feet (500 metres) with a 3 ms response time. Low-voltage alarms sound at 7.2 V and 4.1 V to warn of depleted power. Operation requires either four 1.5 V AA cells, a USB power source or a 2-3S lithium pack connected to the protected socket. A separate dongle is needed for RC simulator use and FPV display mounting is supported but not supplied.

Power flexibility decides suitability

Three charging modes — AA batteries, USB port or 2-3S lithium battery — let you choose the power source that fits your session length and field conditions. The lithium connector includes reverse-polarity protection to prevent damage from incorrect insertion. Buyers who need integrated telemetry beyond voltage alarms or a built-in simulator port without an extra dongle should look elsewhere.

Questions about this item

Should I choose the AA battery option, USB power, or the lithium socket for the transmitter?

The transmitter accepts four 1.5 V AA cells, a USB power port, or a 2–3S lithium battery socket with reverse-polarity protection; pick AA for field convenience, USB for bench charging, or lithium for longest run-time.

What does the 3 ms response time mean when I am driving the car?

A 3 ms cycle gives near-instant servo reaction so steering inputs feel direct and the vehicle tracks exactly where you point it.

How far can I actually control the model with the 2.4 GHz FHSS link?

The pseudo-random FHSS system delivers reliable control up to 1640 feet (500 metres) in open conditions.
