PRODUCT INTRODUCTION

The history of common folk owning cars is not very long. This 'weird' but efficient vehicle was a luxury

only for the very rich, until the advent of mass-produced cars. These days, countries all over the world

have popular affordable cars for the people. Although the original intentions of research and

development vary, their common concepts are compactness, convenience and multi-functionality.

Dr. Ferdinand Porsche, the founder of the Porsche Car company, was a genius designer whose design

ideas have influenced many today. He has designed the Beetle, the Elephant heavy tank destroyer, the

Type82 Kübelwagen, the Type166 Schwimmwagen and Lohner-Porsche Mixed Hybrid, the world's first

car powered by hub-mounted motors in the wheel. While Ferdinand Porsche was designing , Adolf Hitler

was waging war across Europe and plunging the World into chaos. The fates of these two Austrians were

intertwined in the 1930s, when Hitler made two promises to the German people after his election as head

of the Third Reich: one was to have steak on dinner; the other was to have a car for every German family.

The car had a very specific requirement, being able to carry 2 adults and 3 children at the same time, i.e.

a standard German family, and travel at a speed of up to 100km/h, while selling for no more than 1000

Reichsmark.

In fact, during the whole war, none of this people's cars was sold to the people, they were all being

requisitioned by the army and converted into military vehicles, the most famous of which is the

Kübelwagen (Released in Nov, 2021, Product No. 11241) . We feel honored if you already own it in your

RC collection. If not, this car could be a great start to realistic scale RC models. The post-war civilian

version was the Beetle, which later became world-famous.

We start with engine. The Boxer air-cooled engine serves as the core of the car, an engine used in

several later generations of classic cars and lasted 65 years in the Beetle, a saga that came to an end

when the last Beetle, number 21,529,464, rolled off the production line in Puebla, Mexico, on July 30,

2003. Initially the Type82 used a 985cc engine, later upgraded to 1131cc, then gradually increased

displacement, and in the Porsche 356 used a 1488cc engine, doubling the horsepower from the very

beginning. The cylinders of the horizontally opposed engine are distributed on both sides, a 130 motor in

the right cylinder position, and another 130 motor reserved for the left side, which can output twice as

much power when applied to the VW T1 or Porsche356 platform. The engine crankshaft flywheel is

connected by a belt to drive the generator and the cooling fan as well. The semi-circular fan fairing is a

major feature, in which the airflow is distributed to the cylinders on both sides. All is faithfully restored on

the model, meaning you can observe the blades rotating through the fan intake when the motor is

running. The Kübelwagen has 4 forward gears and the maximum speed of each gear respectively goes

as 1st gear 18.4km/h; 2nd gear 32.4km/h; 3rd gear 54.2km/h; 4th gear 83.6km/h. The corresponding red

line of gearshift tips is available on the dashboard. On the model, we designed a 2-speed shift to simulate

the speed of the 1st and 3rd gears of the real car. The power crosses over from the top of the rear axle

differential and then returns to the rear axle. The model shares the same structure as the real engine,

with the benefit of compactness, making it easy to switch between 4WD and RWD modes. This shift

function is perfectly reproduced on the model to provide more driving pleasure when driving off-road.

Background

About Model

Now let’s move to chassis. The popular portal axle in today's climbing car market has been in

mass production for barrel cars as much as 82 years ago, from which wheelside reducer reduction

ratio of 15:21 has learned a lot, making the barrel car chassis minimum ground clearance of

310mm, dwarfing all modern off-road cars on the market today. On the real car, the front and rear

wheel speeds are balanced by increasing the front axle differential gear ratio while on the model

we set the door axle reduction ratio to 1:1 for common front and rear axle differentials.

Solid load-bearing chassis with stamped central ridge tube chassis and body bears high torsional

resistance. The central drive shaft and electrical wiring are hidden in the ridge tube. The one piece

injection model features the texture of metal stamping with plastic as location and size of each

reinforcement are restored according to the actual car. The front and rear wheels adopt

torsion-bar-sprung independent suspension, allowing long travel capability with little space

occupation. We use torsion springs instead of torsion bar springs to present the front and rear

suspension, easy to disassemble and change tuning.

With regards to tires, the car adopts newly developed road tires and can be used with wheel hub

of model Kübelwagen. The simulated wheels need to be fixed with 5 screws like the real car, and

the spare tire in the front is readily accessible after opening the hood. Here you can also charge

the battery at your convenience with battery properly stored in the actual car fuel tank.

Can the doors be opened? Let’s try the door handle. Pull outward- the door can be opened with

the built-in spring lock push, when closed you can hear the spring lock crisp "kata" sound. Door

interiors are engraved with simulated fabric texture; Soft rubber seats share the same soft texture

of the actual car cushion, perfect for 1 / 12 figures. As always does, the model features a servo

operated steering wheel and front wheels for perfect synchronized action.

Generally speaking, rear passengers do not have a separate door which reduced the likelihood of

a successful escape for rear officers in an emergency. To facilitate escape in the event of an attack

and rollover, foldable soft canopy is set in the roof window. In the model, we set up a removable

plastic roof carved with a fine weave pattern to simulate the texture of the cloth canopy. When

removed, figures can be placed in the rear if you like.

For the electronic system, a 4-channel digital proportional remote control system is applied. In

addition to 1&2 channels for steering and throttle control, the 3rd channel controls the gearshift

and the 4th channel switching between 4WD and RWD. There is also integrated light control,

which allows you to turn on the headlights during normal night driving. The taillights are

accompanied by a brake linkage effect.

More exciting product features and designs are right there. Go and discover them yourself.

ESC protection

This receiver has multiple prompt functions such as power-on self-check display, overheating alarm

prompt,and low/high voltage alarm prompt.

• Self-check display: all car lights will be on for 1S when the receiver is powered on;

• Overheating alarm: When the internal temperature of the ESC is detected to exceed 110 °C,motor

has no output, all car lights flash promptly, and the normal output will be restored when the

temperature is lower than 70°C;

• Low/high voltage alarm: When the receiver enters the low voltage protection, motor has no output,

and all the lights flash slowly; when the receiver enters the high voltage protection, all channels have

no output. All car lights flash promptly.

ESC function instructions

1.Connect related equipment:

Make sure the ESC is off before connection.Connect the motor with M+ and M- of ESC. Connect the

steering servo to the 3Pin interface marked with "ST" of ESC (- + S connected

correspondingly).Connect the battery with the positive and negative poles of ESC correspondingly.

2. Normal boot, identification throttle midpoint:

After connecting related equipment as step 1, turn on the radio first, move the throttle trigger to the

neutral position. Turn on the switch of ESC at last. The receiver will automatically recognize the

battery type when it is powered on again. Then it can run it.

Notes:

a. The ESC can be run after completing self-inspection (about 3 seconds) if power on, otherwise it

cannot be operated normally.

b. If there is no power output and the red light of ESC flashes quickly after power on, please check

whether the throttle trim of the transmitter is set to the "0" position, the receiver will automatically

recognize the midpoint of the trim throttle after restarting;

c. If the rotation direction is not correct during running, exchange the two wires connecting motor and

ESC.

d. To make sure everything is ok, please turn on the transmitter first and finally turn on the ESC, turn

off the ESC first and finally turn off the transmitter.

Notes: Please refer to the relevant sections for details about the battery type, drag brake force and

running mode of the ESC.

Binding

The receiver automatically enters the binding state once it is powered on.

Press the BIND Key to turn on the transmitter and allow it to enter its binding state. Here, G.LED

flashes quickly, and operator releases the BIND Key.

1. When the receiver is powered on and waits for 1 second, it will automatically enter the binding state

if it is not connected;

2. After the binding is successful, the LED indicator of the receiver is always on.

Notes: (1) Set the transmitter to its binding state first, and then set the receiver to its binding state. If

the binding is not completed within 10s, the indicator light of the receiver will enter its slow flashing

state. (2) If re-binding is successful, all the settings of the car lights will be restored to their default

values.

This function is used to protect the safety of the model and the operator when the receiver cannot

normally receive the signal from the transmitter and is out of control. The receiver defaults that the

throttle channel is fixed to be out of control and enters the brake state. After other channels are out

of control, the receiver has no signal output. If you set it on the transmitter, it will output according to

the set value.

Attention:

• Make sure the product is installed and calibrated correctly, failure to do so may result in serious

injury.

• Please carefully check each power device and car frame instructions to ensure the power matching

is reasonable before use. Avoid damaging power system due to incorrect matching.

• Do not let the external temperature of the system exceed 90°C /194°F , because high temperature

will damage the power system.

• Make sure the receiver's battery is disconnected before turning off the transmitter, failure to do so

may lead to unintended operation or loss of control.

• After use, remember to disconnect the battery and the ESC. If the battery isn't disconnected, the

ESC will consume electric energy all the time even if it is off. It will discharge completely if connect

the battery for a long time, thus resulting in the failure of the battery or the ESC. We are not

responsible for any damage caused by this!

• Make sure the receiver is mounted away from motors or any device that emits excessive electrical

noise.

• Keep the antenna of the receiver at least 1cm away from conductive materials such as carbon or

metal.

• Do not power on the receiver during the setup process to prevent loss of control.

Battery Type Drag Brake

Setting Method:

There are three parameters can be set for the ESC, which are "Running mode", "Battery type", "Drag

brake", There are slide switches numbered 1 2 3 4 on the radio panel . The above parameters can be

set by dialing down and up.

The specific operation is as follows:

The Dial Switch on the transmitter is used to set ESC parameters, that is, the Dial Switch is located

at different positions and the corresponding parameter values are different.

When No. 1 slide switch is on the down, it indicates that the operation mode is set to

FWD / REV / BRK.

When No. 1 slide switch is on the up, it indicates that the operation mode is set to FWD/REV.

When No. 2 slide switch is on the down, it indicates that the battery type is set to Lipo.

When No. 2 slide switch is on the up, it indicates that the battery type is set to NiMH.

When No. 3 and No.4 slide switch are on the down, it indicates that the drag brake force is set to 0%.

When No. 3 slide switch is on the down and No.4 slide switch is on the up, it indicates that the drag

brake force is set to 50%.

When No. 3 slide switch is on the up and No.4 slide switch is on the down, it indicates that the drag

brake force is set to 75%.

When No. 3 and No.4 slide switch are on the up, it indicates that the drag brake force is set to 100%.

Parameter Explanation:

1. Running Mode

FWD/REV/BRK: This mode adopts "double click” reverse mode, that is, when the throttle trigger is

pushed from netural range to the reverse area for the first time, the motor is only braking and will not

reverse; when the throttle trigger is moved back to the netural range and pushed to the reverse area

for the second time, it will reverse. This mode is applicable to general models.

FWD/REV: This mode adopts "one click" reverse mode, that is, when the throttle trigger is pushed

from netural range to the reverse area, the motor immediately generates reverse action, which is

generally applied to rock crawler.

Parameter setting method:

When No. 1 slide switch is on the down, it indicates that the operation mode is set to FWD / REV /

BRK.

When No. 1 slide switch is on the up, it indicates that the operation mode is set to FWD/REV.

2. Battery Type

There are LiPo and NiMH cells. The low-pressure protection value is different under different types.

It can be set according to the actual use.

Parameter setting method:

When No. 2 slide switch is on the down, it indicates that the battery type is set to Lipo.

When No. 2 slide switch is on the up, it indicates that the battery type is set to NiMH.

3. Drag Brake Force

The drag brake means that when the throttle trigger moves from the forward or reverse area to netural

range, it will produce certain braking force to the motor, the larger the value is, the greater the drag

brake force is. Select proper braking force according to the actual situation.

Parameter setting method:

When No. 3 and No.4 slide switch are on the down, it indicates that the drag brake force is set to 0%.

When No. 3 slide switch is on the down and No.4 slide switch is on the up, it indicates that the drag

brake force is set to 50%.

When No. 3 slide switch is on the up and No.4 slide switch is on the down, it indicates that the drag

brake force is set to 75%.

When No. 3 and No.4 slide switch are on the up, it indicates that the drag brake force is set to 100%.
