AMEWI RC ALLRock H8 Scale Crawler brushless yellow 1/8 ARTR

Product detailed description

ALLRock H8 is a high-class crawler that impresses with the highest quality equipment and excellent driving characteristics. It features top-of-the-line components, including an AC ESC controller with intelligent torque control that can be programmed via a Bluetooth app.

The powerful 3970 AC motor has a chip-supported encoder sensor that works 60 times more accurately than conventional Hall sensors in other AC motors. Servo steering with metal gears and a control force of 35 kg ensures precise steering. The 2-speed gearbox with metal gears enables powerful crawler mode and fast driving. The built-in lighting system with 140 LEDs offers different lighting modes. Portal axles with individually lockable differentials using a remote control increase ground clearance and increase wheel drive thanks to an additional gear ratio.

Aluminum shock absorbers filled with oil at the front and at the back with stainless steel links guarantee optimal handling in any terrain. The rear axle is sprung. All parts of the transmission and drive shafts are made of metal alloys or steel, while the frame is made of 5 mm CNC machined aluminum to ensure high torsional rigidity.

The 80A AC regulator always ensures sufficient power thanks to intelligent torque management. This system recognizes when more power is needed and relays the information to the engine, which delivers more power without changing revs. In addition, the controller has a downhill function, which ensures a constant speed when driving downhill. The sensitive "mountainbreak" brake holds the crawler in place as soon as the driver lets off the gas.

Thanks to IP67 water resistance, the ALLRock H8 RC crawler can be used almost anywhere - from easy terrain to the most demanding passages with heavy obstacles. Under the hinged, magnetically secured body are two large battery compartments. These enable optimal weight distribution depending on the driving situation. A battery compartment above the front axle provides more downforce, while a rear battery compartment adds weight to the rear. It is possible to combine two batteries to increase the total capacity.

The model comes with an 8-channel 2.4GHz remote control system already installed, with free channels for other components such as the winch. The model is delivered in a robust protective case made of EPP foam, which ensures safe transport.

Run-in of the new electric motor
New model with engine, needs to be run in first. Before starting to use the DC electric motor, it is definitely recommended to run it. Some manufacturers require it as a condition for recognizing a possible engine claim. The purpose of the run-in is to seat the rotating parts well, smooth the friction surfaces of the contacts, and grind the carbons into the correct shape. The current enters the motor on the commutator surfaces using the so-called carbons, which may not have a perfectly adapted shape from production. If the new motor is loaded to the maximum without a previous run-in, the commutator surface or the carbons may be damaged due to large "sparking". The run-in will allow the carbons to settle on the commutator as perfectly as possible. Thus, the carbons will wear out less and last longer.

Electric motor run-in procedure:
-If you have a new RC model car or boat in which the engine is already mounted, proceed as follows. Place the model on the mat so that the wheels rotate above the surface. Let the engine run at the lowest possible speed for at least 20-30 minutes. You can then drive the model for 20-30 minutes at a lower speed and gradually increase the speed. Drive the model at full power only after the run-in phase has passed.

-If you have a new engine that has not yet been installed in the model, you can do the run-in in the traditional, proven way by immersing it in water. Connect the motor to the ESC controller and lower it by the cables vertically down into a container of clean water. Start the engine at low speed and let it run for 10-15 minutes. Then you can gradually increase the speed for a few minutes up to the maximum. finally, take the motor out of the water and let it run for a while to blow the water out of the motor. You can mount a run-in engine in the model and you can immediately drive at full power. You don't have to worry about the engine submerged in water. It will work normally and the water will cool it during the run-in. In addition, it washes out carbon particles during grinding (the water visibly darkens).

Protection against overheating of the electric motor:
Since the stator is made up of permanent magnets, it is good to know that these magnets gradually lose their "power". However, temperature also has a big impact. Each electric motor heats up during operation and can reach a temperature of 60°C (therefore, the motor must never be touched with bare hands after driving!). However, if the engine is not cooled or cooled insufficiently, or if it is driven for a long time at maximum speed, it may overheat and thus weaken the magnets. Even after cooling down, the engine will no longer reach its previous performance. Of course, other parts of the engine can also be damaged by high heat. It is therefore advisable to change the load mode, or to drive with two smaller accumulators with a break for replacement and cooling, rather than with one large-capacity one for a long time at full power.

Electric motor replacement, tuning:
If you decide to replace the electric motor in this model, pay attention to the following recommendations.
The new motor should be of the same type (size), have the same number of turns and the same supply voltage value as the original one. That way, you will be sure that the model will retain its original driving characteristics.
If you are planning a tuning motor, first of all, check whether the original ESC controller in the model will be able to work with the tuning motor, in order not to burn the ESC controller, or to prevent the ESC-motor system from working. When tuning a motor, it is usually necessary to replace a pinion with a different number of teeth.

WARNING! This RC car is not a toy, but a more sophisticated, functional model that behaves very much like a real car. Due to its realistic parameters, if it is not properly assembled and operated, it can cause you injury, or injure the viewer, or damage property. The model is intended for driving in a large room or outside on a dry surface. Driving in water, in snow, in puddles, mud, sand, in tall grass without appropriate waterproof treatment can cause damage to the electronics of the model. Driving on public roads and other places (e.g. parking lots) with car traffic is prohibited. Do not drive in thick grass, you will overheat or burn the engine!
This model requires regular maintenance, by disassembling it correctly according to the service manual, you will not lose the warranty.
