- Brushless car: about 60-70 km/h.
- Brushed car: about 20-30 km/h.
- Crawlers: about 10-20 km/h.
- Nitro car: about 50-70 km/h.
A: We recommend starting with a 1/10 scale entry-level model (e.g., an electric off-road buggy). Opt for an RTR (Ready-to-Run) version with a basic transmitter and charging kit - it's affordable and beginner-friendly.
A: We offer two options:
RTR (Ready-to-Run): Fully pre-assembled, includes transmitter, battery, and charger - play right out of the box.
KIT (Rolling Chassis): For advanced users; allows custom motor, ESC, and electronics pairing.
A: Both have pros and cons:
Electric (brushless/brushed): Quiet, low-maintenance, ideal for urban/indoor use (~20min runtime).
Nitro: More powerful, longer runtime (1-2hrs), but noisy and requires regular engine maintenance.
A: Yes! We suggest 1/10 scale electric rock crawlers or brushed cars - slower speed and simplified controls.
A: Water resistance varies by model. Some are designed to withstand light moisture (e.g., damp surfaces), but most should avoid heavy rain or submersion to prevent electronics damage.
A: Our brushless models use LiPo (lithium polymer) batteries; brushed models use NiMH (nickel-metal hydride).
A: Yes! They're easy to operate, but we recommend adult supervision for children under 14.
A: Small, low-speed models work indoors, but larger/faster cars are best for outdoor spaces.
A: Always drive in open areas away from people/vehicles. For electric cars: avoid touching the motor/ESC when hot. For nitro: never touch the engine post-run to prevent burns.
A: Parts are available at specialty RC shops, online retailers, or directly from us (contact customer service for details).
A: Three effective methods:
- Upgrade to a high-KV brushless motor
- Install a larger spur gear (e.g., from 48T to 52T)
- Use higher-voltage batteries (e.g., 2S → 3S LiPo)
Note: Ensure proper heat dissipation and chassis reinforcement.
A: Troubleshoot step-by-step:
1. Check battery levels in the transmitter/receiver
2. Rebind the system (follow the manual's pairing steps)
3. Inspect motor/ESC wiring for loose connections
4. Power-cycle all electronics
5. Examine the drivetrain (pinion gear, spur gear, differential, drive cups)
6. If issues persist, contact customer support.
A:
- LiPo (3300mAh): ~10-15 mins (varies with driving intensity)
- NiMH (1800mAh): ~10-12 mins
Tips: Minimize full-throttle use; turn off lights/fans.
A: Depends on capacity:
7.2V 1800mAh NiMH: ~3-4 hours
7.4V 3300mAh LiPo: ~4 hours
A: Yes, if compatible with your model. Larger capacities extend runtime.
A: Store in a cool, dry place. Always charge in a fireproof LiPo bag.
A: Please Try:
1. Lowering shock absorber height
2. Adding weight blocks (e.g., front weights for climb stability)
3. Switching to low-CG tires (wide, soft compounds)
A: Yes! But:
- Install dust covers to protect drivetrain.
- Use low-temperature batteries (above -10°C).
- Clean and lubricate metal parts afterward to prevent rust.
A: Required items:
- Remote Control Batteries
- Receiver power source
- Nitro fuel
- Glow igniter or starter box
A: Methanol-based fuel (environmentally efficient). Recommended:
1/10 scale: 15-20% methanol
1/8 scale: 20-25% methanol
A: Typically 15-20 minutes (engine size/tuning/driving style dependent).
A:
(1) After fueling, cover the exhaust port, pull the puller a few times to get fuel into the engine.
(2) Ignition plugged into engine ignition and pull puller.
(3) Once the engine is started, remove the ignition.
Starting a nitro engine requires running several tanks of fuel at low to medium speeds to ensure proper piston and bushing position. Follow the specific engine manufacturer's instructions.
A: Tuning involves adjusting the primary, secondary and idle oil needles for optimum performance. Proper tuning ensures that the engine runs smoothly and efficiently. For more details, you can view the nitro truck tuning video or contact customer service.
A: Common causes:
Improper commissioning
Clogged air filter
Insufficient fuel or clogged fuel lines
Check these components and tune the oil needles as needed.
A: When the engine is fed with too much oil, there is an "Du Du Du" abnormal sound coming from the engine and there is oil spraying from the exhaust pipe. In this case, the engine is easy to overheat, fuel consumption. You can try to adjust the carburetor needle, adjust the engine oil intake.
A: Cover the exhaust with a cloth or heat-resistant material.
A: The method of restoring the factory commissioning settings of the engine oil needle: the general situation is to tighten the oil needle inward, and then back to adjust 2 ½ to 3 turns.
A: No. nitro engines need methanol fuel, and if you use gasoline, it will cause damage to the engine.
A: The remote control distance is about 100-150 metres (open environment), with 2.4GHz anti-interference technology, automatic frequency hopping to prevent conflicts when multiple RC cars are competing in the same arena.
A:
- Lithium batteries: Avoid overcharging/overdischarging (single cell voltage should not be lower than 3.2V), and charge them to 3.8V/cell when storing for a long time.
- Nickel Hydride Battery: Fully discharged before charging to avoid the "memory effect".
Avoid storing the battery for a long time, check the battery and charge it regularly to avoid over-discharge.
A: Immediately disconnect the power and follow the steps to deal with it:
1. Remove the shell of the vehicle, use a dry cloth to absorb the water;
2. Wipe the electronic equipment (ESC, receiver) with anhydrous alcohol;
3. Let it dry for 24 hours and then test it under power.
A:
- Remove the battery and store it separately.
- Apply antirust oil to metal parts.
- Shock absorbers are relieved of pressure to avoid long-term spring compression.
A: Clean your RC nitro car after each run to remove dirt, debris and excess oil and check for loose chassis screws. Regular inspection and cleaning will help maintain the performance of your car and extend its life.
A: Yes, you can upgrade components such as the motor, ESC, battery, tires, frame metal parts and bodywork to improve performance and durability.
Popular upgrades include switching to a brushless motor, upgrading to a higher capacity lithium battery, installing better tires, and adding aluminum or carbon fiber parts.
A: Metal parts (e.g. aluminium swingarm, steel drive shaft) are strong and suitable for racing or violent driving, and it is recommended to upgrade according to the needs.
A: Choose according to the terrain:
- Road: bald tyre (high grip)
- Gravel/Mud: studded tyres (deep grain drainage)
- Climbing: soft sponge tyre (enhanced traction)
A: Some models can be retrofitted with LED light clusters (please consult customer service first if required).
A: Two ways:
- Replace the low-viscosity shock oil;
- Adjust the shock spring preload (tighten clockwise to increase the stiffness).
A:
- Spot order: Shipped within 72 hours (3-7 days to arrive within China).
- Customised models: 20-30 working days (according to the number of orders to determine the time).

A: Step-by-step troubleshooting.
If it is a electric car check:
(1) Check if the batteries on the car and the remote control batteries are charged;
(2) Check if the throttle rudder adjustment (TH.D/R) on the remote control is set to minimum;
(3) When the ESC is switched on, whether the indicator light is normal and whether it operates normally;
(4) When the power is on, check if the motor is working properly. If the motor is normal, check if the motor teeth are locked and if the motor is idling;
(5) Check whether the motor teeth, gear reduction teeth, and gear box gears are swept teeth (whether the gears have abnormal noise);
(6) Check whether the vehicle transmission from motor pinion gear to spur gear, from slipper system to front or rear differential, then to CVDs or dogbones is locked;
(7) If the remote control and the car are powered on normally, it may be that the remote control can not be connected to the receiver, and the customer needs to operate the remote control and the receiver according to the remote control instructions for the code.
If it is a fuel car check:
(1) Check whether the batteries of the remote control and the batteries for the receiver are charged;
(2) Check whether the throttle rudder volume adjustment (TH.D/R) on the remote control is set to minimum;
(3) Check engine gears, centre differential gears, and gearbox gears for swept teeth (gears for rattling);
(4) Check if the vehicle transmission catch cup is locked;
(5) If the remote control and the car are powered on normally, it may be that the remote control can not be connected with the receiver, and the customer needs to operate the remote control and the receiver according to the remote control manual.
If you still can't get the response after the above checking, please consult the customer service.
A: Check if the throttle reverse switch (TH. REV) is set to the opposite, as well as checking if the motor wiring is reversed.
A: Check whether the direction reversal switch (ST. REV) is set to the opposite direction.
A: Check if the servo and ESC (Electronic Speed Controller) wires are plugged into the wrong channels on the receiver:
- Steering servo should connect to Channel 1 on the receiver.
- ESC must be plugged into Channel 2 on the receiver.
A:
(1) Check whether the battery is charged; whether the ESC is energised;
(2) Check whether the steering servo is working properly, whether the servo has sweeping teeth and abnormal rattling sound;
(3) Check whether the steering rudder volume adjustment (ST.D/R) on the remote control is set to the minimum, so that the adjustment of the servo becomes 0.
A:
(1) This may be due to a low battery, a worn motor or too much dirt in the drive train. Check and clean the car and charge or replace the batteries;
(2) Check the throttle rudder volume (TH.D/R) of the remote control. Adjust the throttle rudder level.
A: Common causes:
- Gears are too tight or jammed
- Using too high a voltage (e.g. 3S battery exceeds motor rating)
- Motor runs at full throttle for long periods of time
A: Common causes include remote control power, water in the engine, improper adjustment or insufficient fuel. Check these parts to make sure the spark plugs are working properly.
A: It may be caused by insufficient fuel, improper needle adjustment or insufficient cooling.
A: It is possible that the remote control and receiver power supply batteries are dead, causing the car to be out of control.
A: A bad spark plug will prevent the engine from starting. Test the spark plug with the ignition; if it fails to emit a bright light, it is bad and needs to be replaced.
