ALLRock H8 V2 Scale Crawler brushless 1/8 RTR blue/orange

Product detailed description

ALLRock H8 V2 is a top crawler that impresses with its modern equipment, sophisticated chassis layout and excellent driving characteristics.

In the V2 version, numerous technical innovations ensure higher off-road performance than its predecessor. The model is equipped with top-notch components, including a brushless ESC controller with intelligent torque control, the settings of which can be conveniently programmed using an app on a smartphone with a Bluetooth interface.

The powerful 3970 brushless motor is equipped with a chip sensor that is 60 times more accurate than Hall sensors in conventional brushless motors. Servo with metal gears and a force of 35 kg ensures precise steering. A sophisticated 2-speed metal gearbox, which, thanks to its extremely robust design, ensures optimal performance at slow (crawling) as well as fast driving. Maximum traction is ensured by new tires that offer even greater grip on a wide range of surfaces - whether rocks, gravel, sand or forest soil. Portal axles with individually lockable differentials (via remote control) increase ground clearance and, thanks to an additional gear ratio, strengthen the wheel drive. New nylon-reinforced axle covers further increase the model's stability and durability.

The new chassis layout with even lower components in combination with a large battery compartment at the front ensures a significantly lower center of gravity and better weight distribution. This keeps the crawler safe and maneuverable even on extreme inclines. Aluminum oil shock absorbers at the front and rear as well as stainless steel arms guarantee optimal maneuverability. The rear axle is suspended via an additional joint, which allows it to be even more articulated. All transmission parts and drive shafts are made of metal alloys or steel, while the frame is made of 5mm CNC milled aluminum to ensure high torsional rigidity.

The 80A brushless ESC ensures constant sufficient power without changing the speed thanks to intelligent control. The system automatically detects increased power requirements and transmits the appropriate information to the motor to achieve higher power without losing speed. The adjustable BEC output voltage (6V/7.4V) allows the use of high-voltage servos, winches, etc. In addition, it has a function that ensures consistent speed when driving downhill.

The sensitive MountainBreak reliably holds the crawler in place as soon as the driver releases the throttle. Thanks to the IP67 waterproof rating, the ALLRock H8 V2 Crawler can be used almost anywhere - from easy terrain to the most demanding passages with heavy obstacles. Under the hinged, magnetic body, there is a generously sized battery compartment in the front, which allows for quick battery replacement.

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.
