Amewi RC ALLRock H8E Pick-up Crawler brushless FOC 1/8 RTR

Product detailed description

The 1:8-scale ALLRock H8E Pick-up Crawler combines high-quality technology with robust construction and precise handling for demanding crawling. The brushless FOC motor/speed controller combination, featuring intelligent torque management and a chip-controlled sensor system, enables exceptionally responsive handling and precise control of drive power. The chassis, with its low centre of gravity and large, front-mounted battery compartment, further enhances climbing performance. The H8E is supplied as an RTR (Ready-to-Run) model, including an interference-free 2.4 GHz radio control system, a 3S LiPo battery with 11.1 V and 5000 mAh, and a charger.

To ensure durable and precise power transmission, the drivetrain and gears are made from steel and robust metal alloys respectively. The fully ball-bearing-equipped suspension features portal axles at the front and rear for greater ground clearance, nylon-reinforced axle housings, stainless steel links for chassis bracing and a 5 mm aluminium frame. The crawler tyre and rim combination ensures high grip on a wide variety of surfaces. The differentials, which can be locked individually via the remote control, allow for precise adjustment of traction to suit demanding driving conditions.

The latest-generation, switchable 2-speed gearbox is made of metal and is controlled by a 17g servo. A 17g servo is also available for the differentials. A powerful 35kg steering servo with a metal gearbox, steering damper and partially metal housing ensures powerful and precise steering. The ESC’s adjustable BEC output voltage of 6V or 7.4V allows for the use of additional components such as high-voltage servos or a cable winch. The ESC can also be programmed via Bluetooth using a smartphone app for Android and iOS.

Thanks to IP67-rated water protection, the H8E is designed for off-road use and a variety of outdoor conditions. The magnetically attached body is additionally secured at the front with a locking screw, whilst also allowing easy access. The LED lighting, which can be switched on and off via the remote control, expands the range of applications in low-light conditions. The H8E thus offers a comprehensive range of features, designed for durability and demanding off-road driving, for model builders aged 14 and over who value high-quality materials and precise engineering.

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.
