DumboRC X6 with X6F Receiver Is an Affordable 6-Channel 2.4 GHz Radio with FHSS and a Range of Over 400 m Without a Gyro

DumboRC X6 with X6F receiver is a 6-channel 2.4 GHz RC transmitter intended mainly for cars, boats, and tanks. The X6 + X6F combination is a simpler version without a built-in gyro in the receiver.

Technical documentation for DUMBORC series receivers lists 6 channels, FHSS, operation in the 2.4 GHz band, and a stated range of more than 400 meters.

The balance of price and range is precisely why the X6 has become popular with budget RC cars.

Six channels offer more than a typical RTR controller

An inexpensive Ready-to-Run car often uses only:

• CH1 steering,
• CH2 throttle.

The X6 offers additional channels for:

• lights,
• a winch,
• a gearbox,
• an additional servo,
• sound,
• accessories.

Six channels are easy to make use of in a scale crawler or tank.

X6F is the version without a gyro

That is important with this offering.

X6F does not have an integrated gyro.

If the user wants electronic steering stabilization, they need one of these variants:

• X6FG,
• P6FG,
• or another gyro version compatible with the X6.

Without a gyro, the receiver is suitable where the driver wants completely manual control.

That is often desirable in a crawler.

A gyro can help in a fast on-road car.

FHSS

The documentation lists FHSS – Frequency Hopping Spread Spectrum.

The system changes the frequency it uses within the 2.4 GHz band according to its own algorithm.

This helps with resistance to interference in environments where the following operate:

• Wi-Fi,
• Bluetooth,
• other RC systems.

FHSS alone does not guarantee unlimited range, but it is a common foundation of modern RC radios.

Stated range of over 400 meters

The X6F/P6F receiver documentation lists more than 400 m.

This figure depends on ideal conditions.

Real-world range is affected by:

• antenna orientation,
• interference,
• receiver position,
• a metal or carbon frame,
• power supply.

For an RC car, 400 m is still more than most users need, because the model is already difficult to see at that distance.

The receiver operates at approximately 3.3 to 10 V, depending on the version

Documentation for newer X6F/P6F receivers lists a wide power supply range of approximately 3.3–10 V DC.

This is practical with different BEC systems.

However, the servos must also be checked.

If the receiver tolerates 8.4 V, that does not automatically mean a standard 6 V servo will survive that voltage.

Power consumption of around 30 mA

The receiver has very low power consumption of its own, approximately 30 mA.

The greatest current draw in an RC car therefore typically comes from:

• the servo,
• the ESC,
• lights,
• other accessories.

The BEC must be sized for the entire system.

The 6-channel receiver is compact

Technical materials for the series list dimensions of approximately:

• 35 × 20 × 13 mm

for some versions.

That is small enough even for a 1:18 or 1:16 model.

For a watercraft model, however, protect the receiver from moisture if that specific unit does not have clearly stated waterproofing.

The X6 is primarily a surface radio

The pistol-grip transmitter’s ergonomics are suitable for:

• cars,
• boats,
• tanks.

It is not a conventional aircraft radio with two control sticks.

Even though it has six channels, that does not mean it is practical for an aircraft.

Trim and basic channel adjustments

The X6 allows adjustment of the basic steering and throttle functions.

After the first pairing, check the following on an RC car:

• servo direction,
• neutral,
• end points,
• throttle direction,
• failsafe.

At neutral, the wheels should point straight without the servo constantly pushing against a mechanical stop.

Test the failsafe

Before driving:

1. turn on the car, 2. leave the wheels off the ground, 3. apply a little throttle, 4. turn off the transmitter.

The motor should go into a safe state.

On a model without a correctly configured failsafe, losing the signal can result in an uncontrolled run-off.

When does the version without a gyro make sense?

The X6 + X6F is a good choice for a:

• crawler,
• trail truck,
• boat,
• tank,
• slower RC car.

A gyro can even be annoying in a slow crawler, because it automatically corrects the steering where the user wants to control the wheels precisely themselves.

Main specifications of the DumboRC X6 + X6F

Who is the X6 suitable for?

It makes the most sense for someone converting or building their own RC car who wants more channels than basic RTR electronics offer.

Is the DumboRC X6 with X6F worth it?

Yes, if you do not need a gyro.

For a low price, it offers 6 channels and a very respectable stated range.

For a fast drift or on-road car, a gyro version may be more interesting. For a crawler and a universal surface model, the X6F is a simple and functional solution.
