Since the questions about the correct settings in Facebookgroups and forums pile up, here is a short explanation about the programming.

Hobbywing 1080 Quicrun

Who buys the Hobbywing 1080 Quicrun gets this in a box with a programming card. If who bought the controller used and it is missing the card you have a problem if you do not already have one lying around at home.

All settings of the controller are made via this card, some of them are really important!
How the whole thing is then set is for many then but a book with seven seals and for some not meaningful enough

Set and understand HW 1080

• 1. Running mode

At this position we select the way the controller works. For selection we have:
(1) Fwd/Brk - only forward and brake
(2) Fwd/Rev/Brk - Forward / Brake / Reverse
(3) Fwd/Rev - Forward - Reverse

For us crawlers, the value 3 is the correct setting.

• 2. Battery Type

Here we choose the type of battery we want to drive.
(1) LiPo
(2) NiMH

You probably know best with which battery you are driving.

• 3. Cutoff Voltage

Here you can set the cutoff voltage for lipo batteries. This is very important because a lipo that is deeply discharged will suffer damage. The controller monitors the voltage and switches off as soon as the voltage falls below a certain level.
(1) disabled - switched off recommended for NiMH batteries
(2) Auto low - automatically low (3,0V per cell)
(3) Auto medium - automatically medium (3,2V per cell)
(4) Auto high - automatically high (3,4V per cell)

The best is here the value 4 because here you have the highest battery protection. If you don't use your crawler to full throttle all the time you can live with the value 3.

Attention who enters here value 1 should absolutely use a Lipowarner to avoid damage to his precious batteries.

• 4.Initial Start Force

Here we set the initial speed that is released when we press the throttle. A low value lets our crawler start more sensitive.
(1 - 9) 0% - 16%

Optimal value 1-3, best to test it because it also depends on the used engine and the vehicle weight.

• 5. Max. Forward Force

Here we set the maximum forward speed that can be achieved.
(1) 25%
(2) 50%
(3) 75%
(4) 100%

The value 4 really makes sense here. For the beginner or the junior, however, you can also choose a lower value if you want to familiarize yourself with the vehicle.

• 6. Max.Reverse Force

Here we set how fast the vehicle can drive backwards.
(1) 25%
(2) 50%
(3) 75%
(4) 100%

A reasonable value of 1 or 2 makes our crawler drive more realistic, because cars in reality rarely drive 100km/h in reverse. But everybody has to decide for himself.

• 7. Max. Brake Force

In driving mode 3 this function is without function. Therefore the value does not matter.

• 8. Initial Brake Force

In driving mode 3 this function is without function. Therefore the value does not matter.

• 9. Drag Brake ESC

Here you can set the maximum braking power that the ESC passes on to the motor. A high value increases the braking power.
This brake is also often called hillbrake or handbrake. On very steep terrain you will rarely succeed in nailing the car to the ground, it will mostly roll slowly downwards. If you want more here you can't avoid a sensor controlled motor/controller combo.
(1 - 9) 0% - 100%

The best value to choose is 9 because it has the highest braking effect.

• 10. Drag Brake Rate

When you move the throttle from the throttle position to neutral, this value determines how quickly the brake is applied.
This can be compared with a car if you press the brake pedal directly through the floor. A lower value lets the brake intervene more gently.
(1 - 9) Strength 1-9

There is no optimal setting here, but a value of 1-4 is useful so that the car does not roll over directly with a forward somersault when going steeply downhill.

• 11. Neutral Range

This is about the area around the throttle control and how far you have to move it for something to happen or not happen to the vehicle.
When the lever is in the neutral position, the engine should not move. The smaller this value, the faster the crawler responds.
(1 - 9) Level 1 - 9

there is no recommendation here, you have to try out the value.

• 12. Start Mode/Punch

A high value here behaves like the kickdown on the automatic, the vehicle accelerates fully and very aggressively. A lower value allows the crawler to accelerate more slowly and in a more controlled manner. However, the whole thing also depends on the selected engine. Best just test it.
(1-9) Level 1-9

A value of 1-4 is recommended, but should be adjusted individually.

• 13. PWM Frequency

An extremely important setting on the 1080 Quicrun. It stops this annoying beeping of the controller which is responsible for the "crawler tinnitus".
A higher value also allows the controller to work much more sensitively, but this is also associated with a higher operating temperature.
(1) 1Khz
(2) 2Khz
(3) 4Khz
(4) 8Khz
(5) 16 Khz

A value of 3 or higher is recommended, since the heat generation of the crawler is not particularly high. To remove the annoying beeping completely, select a value of 5.

• 14. BEC Voltage

The controller also supplies power to the receiver which then powers the servos. Not all receivers and even less the original switch servos from the TRX are designed for more than 6 volts. Therefore, only change the value here to 7.4 volts if another receiver and also switch servos are installed.
(1) 6 Volt
(2) 7,4 Volt

The safe way would be value 1.

• 15. Freewheeling

It is best to activate the crawler because it keeps the speed more constant, which is desirable when driving slowly.
(1) enabled (2) disabled

The value here is 1.

Hobbywing Xerun Axe Combo

The HW Xerun Axe combo also needs to be programmed so that it knows how to react. With the Axe combo, however, there are two different versions.
The difference is in the programming, in addition, the new controller has the possibility to put on a fan that is also included with the combo.
In the new version with new firmware has come in the menu an item (RPM/Throttle Matching).

Setting and understanding Xerun Axe

• 1. Cutoff Voltage

Here you can set the cutoff voltage for lipo batteries. This is very important because a lipo that is deeply discharged will suffer damage. The controller monitors the voltage and switches off as soon as the voltage falls below a certain level.
(1) disabled - switched off for NiMH batteriess
(2) Low (3,0V per Cell)
(3) Medium (3,2V per Cell)
(4) High (3,4V per Cell)

The best value here is 3 because you have a high battery protection. However, those who constantly drive their crawler at full throttle (crawler bashing) should rather take the value 4.

• 2. RPM/Throttle Matching

This is about the automatic readjustment of the speed when the vehicle is driven to an obstacle, for example. The sensor control adjusts the motor here, so that a constant speed is always maintained. The same applies when driving downhill, the speed controller automatically adjusts the motor to the situation and the crawler does not accelerate suddenly.
(1) Low
(2) Medium
(3) High

The best value here is 3, since you have absolute control over the sensor control and the speed is always precisely adjusted via the controller. Otherwise, just try out how your crawler behaves with the other values.
This position is not available with the old firmware.

• 3. Max. Forward Force

Here we set the maximum forward speed that can be achieved.
(1) 25%
(2) 37,5%
(3) 50%
(4) 62,5%
(5) 75%
(6) 87,5%
(7) 100%

The value 7 100% probably makes sense here. For the beginner or the junior, however, you can also choose a smaller value if you want to familiarize yourself with the vehicle.

• 4. Max.Reverse Force

Here we set how fast the vehicle can reverse.
(1) 25%
(2) 37,5%
(3) 50%
(4) 62,5%
(5) 75%
(6) 87,5%
(7) 100%

A reasonable value of 1 - 3 lets our crawler drive more realistically, since cars in reality are rarely 100km/h in reverse. But everyone must decide for themselves.

• 5. Turbo Timing - Turbo Timing

The turbo timing is triggered in the full throttle position. It is basically the same thing that is achieved by twisting the brush motor, but here on the electronic side. Who does not know what he is doing, just leave it as it is.
In the crawler range not really so important because the full throttle range does not play a real role. Certainly interesting for people who use the crawler as a lightbasher.

0° - 10° adjustable in 1 degree steps - factory setting is 0°.

It is best to test the whole thing, if desired, otherwise leave the value 0 (1°) at the factory setting.

• 6. Turbo Delay - Turbo Verzögerung

The turbo delay is the time that passes when the turbo is triggered when pulling the throttle and can be delayed up to 0.5 seconds. This is also not really important in the crawler range.
(1) Instant
(2) 0,1s
(3) 0,2s
(4) 0,3s
(5) 0,4
(6) 0,5s

The safe way here would be value 1 (immediately).

• 7. Max. Brake Force

This is about the braking force of the brake. This is especially important on slopes because the sensor-controlled engine system the crawler really rolls absolutely zero.
Actually, 100% is sufficient here, but if the car is heavier it can make sense to increase the value, just test it..

50-200% adjustable (default: 80%).

I recommend here something value from 100% because it is just to nail the crawler in the slope so that he no longer rolls a millimeter.

• 8. Drag Brake Rate

When you move the throttle from the throttle position to neutral, this value determines how quickly the brake is applied. This can be compared with a car if you press the brake pedal directly through the floor. A lower value lets the brake intervene more gently. In the automatic mode the brake curve is adapted to the driven speed.

Level 1-9 and Automatic

I recommend value 1-4 so that the braking process remains realistic and the rear wheels do not lift off the ground during full braking. I personally did not like the automatic mode for crawling.

• 9. Neutral Range

This is about the area around the throttle control and how far you have to move it for something to happen or not happen to the vehicle.
When the lever is in the neutral position, the engine should not move. The smaller this value, the faster the crawler responds.

6% - 17% adjustable (default: 10%)

There is no recommendation here, try the value.

• 10. Start Mode/Punch

A high value here behaves like the kickdown on the automatic, the vehicle accelerates fully and very aggressively.
A lower value lets the crawler accelerate slower and more controlled. But it also depends on the selected engine. Just test it.

Level 1-9

Optimal is a value 1-3 to enable an extremely sensitive start.

• 11. BEC Voltage

The controller also supplies power to the receiver which then powers the servos. Not all receivers and even less the original switch servos from the TRX are designed for more than 6 volts. Therefore, only change the value here to 7.4 volts if another receiver and other switching servos are installed.
(1) 6 Volt
(2) 7,4 Volt

The safe way would be value 1.

• 12. Motor Rotation

Here we set the direction of rotation of the motor, counterclockwise (CCW) or clockwise (CW).
(1) CCW
(2) CW

For the TRX4 we choose here the value 2. After saving in the app please switch off the controller once and switch it on again so that this value is also taken over.

HW Xerun Axe "Pairing"

After you have installed a new firmware version on the Xerun Axe combo, you often have to reconnect the controller and motor "pairing".
If the software requires you to do this, don't panic, it's not a big deal.
The controller must be disconnected from the receiver, so open the receiver box and pull the plug in slot "2 TH - Throttle". Then loosen the motor mount and remove the motor and plate from the guide and place it on the car. This is important because the motor must be able to rotate freely when pairing.
I would not remove the gear if the engine has been in use for some time because it is difficult to find the original position (engine pinion and gear have run in on each other).

For the actual pairing process, switch on the controller with the battery connected until it flashes red, and then press the programming button (set button) for 3 seconds.
The motor will now start to rotate on its own and run through a program (first slowly, then faster).
When the pairing is finished the controller beeps and the pairing was successful. Now reassemble everything and off you go into the forest.

Hobbywing Xerun Axe R2 Combo

With the combo Xerun Axe R2, Hobbywing has once again made a big change. You need a new software to program this combo and also the optics within the programming has changed significantly. The sensor connector has become much smaller and there are other KV values. The real differences we find however in the technical data. On the ESC, we have 6 amps on the R2 combo instead of the previous 4A and the continuous power has increased from 60 amps to 80 amps. As with the Xerun Axe FOC V1.1, the motor is available in 540L ( 1400KV, 2100KV, 2800KV ) and 550 ( 3300KV ). Completely new is also the possibility to program the motor for forward / reverse with brake. Whether this is really an important function for crawling I leave to each individual.

I was asked by a friend to point out that the new Xerun Axe R2 motor has a different length, it is 540L motor with 57.8mm length and thus 9mm longer than a standard 540 motor. It will fit in a TRX4 without any problems.

Xerun Axe einstellen und verstehen

• 1. Running Mode

Here the driving mode of the motor/controller combo is set.
(1) Forward and Reverses
(2) Forward/Reverse with Brake
For crawlers only position 1 makes sense. The point 2 is rather the training mode so that inexperienced drivers do not go immediately from forward to reverse. To get into reverse gear in mode 2 the throttle has to be moved forward 2 times. The first time the engine only brakes in this setting, only the second time the throttle is moved forward the reverse gear is engaged.

The best here is the value 1 for crawler drivers.

• 2. Cutoff Voltage

The cut-off voltage for lipo batteries is set here. This is very important because especially a lipo that is deeply discharged suffers damage. The controller monitors the voltage here and switches off as soon as a certain voltage is fallen below.
(1) disabled - recommended for NiMH batteries
(2) Low (3,0V per cell)
(3) Medium (3,2V per cell)
(4) High (3,4V per cell)

The best value here is 3 because you have a high battery protection. However, if you constantly drive your crawler at full throttle (crawler bashing) you should rather use the value 4.

• 4. Max. Forward Force

Here we set the maximum forward speed that can be achieved.
(1) 25%
(2) 37,5%
(3) 50%
(4) 62,5%
(5) 75%
(6) 87,5%
(7) 100%

The value 7 100% makes sense here. For the beginner or the junior you can also choose a smaller value if you want to get familiar with the vehicle.

• 5. Max.Reverse Force

Here we set how fast the vehicle can reverse.
(1) 25%
(2) 37,5%
(3) 50%
(4) 62,5%
(5) 75%
(6) 87,5%
(7) 100%

A reasonable value of 1 - 3 lets our crawler drive more realistically, since cars in reality are rarely 100km/h in reverse. But everyone must decide for themselves.

• 6. Turbo Timing

The turbo timing is triggered in the full throttle position. It is basically the same thing that is achieved by twisting the brush motor, but here on the electronic side. Who does not know what he is doing, just leave it as it is.
In the crawler range not really so important because the full throttle range does not play a real role. Certainly interesting for people who use the crawler as a lightbasher.
Basically, if you pull the throttle completely, you have the afterburner for the final punch.

0° - 10° adjustable in 1 degree steps - factory setting is 0°.

The whole thing is best, if desired, test otherwise value 0 (1°) on factory setting leave.

• 7. Turbo Delay

The turbo delay is the time that passes when the turbo is triggered when pulling the throttle and can be delayed up to 0.5 seconds. This is also not really important in the crawler range.
(1) Instant
(2) 0,1s

Level 1-9

Optimal is a value of 1-3 to allow an extremely sensitive start. Attention Level 7-9 have higher requirements for the discharge rate of the Lipo.

• 12. BEC Voltage - BEC Spannung

The controller also supplies power to the receiver which then powers the servos. Not all receivers and even less the original switch servos from the TRX are designed for more than 6 volts. Therefore change the value here to 7.4 volts only if another receiver as well as other switching servos are installed.
(1) 6 Volt
(2) 7,4 Volt

The safe way would be value 1.

• 13. Motor Rotation

Here we set the direction of motor rotation, counterclockwise (CCW) or clockwise (CW).
(1) CCW
(2) CW

QuicRun Fusion BL SYS

The company Hobbywing also offers a motor with flanged controller, basically the whole thing looks like a motor, but there are more cables installed in the back. The whole thing hears on the sonorous name "QuicRun Fusion BL SYS for Crawler-540 Spec" and lets recognize in the name that it is a purebred crawler system.
Besides the connection for the battery, there is a BEC output to the receiver and another cable on which the on/off switch is located.
The whole thing is sensor controlled and offers a similar range of functions as the Xerun Axe and offers like the Quicrun 1080 a programming card for the settings.
The whole thing is available as 1800 and 1200 version, a 2300 there is not because here probably the power consumption at full load would not have fit into the very compact design.
Intended primarily for pure scalers where the space is generally always very limited. The driving fun is like the Xeruns extremely high and does not differ, but the adjustment options are somewhat limited. The brake, for example, can not be set to "automatic".

QuicRun Fusion einstellen und verstehen

• 1. RPM/Throttle Matching

Setting whether the controller should adapt the motor to the preselected throttle range. Basically we switch the FOC system on or off here, in the switched on state the engine is always adapted to the throttle range selected by us via the sensor control.
(1) Enabled
(2) Disabledt

For us crawlers, the value 1 switched on here is the correct setting

• 2. LiPo/NiMH Cells

Here we can choose whether we drive with 2S or 3S Lipos or let it decide the controller itself. With NiMH batteries must be selected here automatically.
Who always drives with 2S or with 3S should preset this value to adjust the battery management better.
(1) auto
(2) 2S
(3) 3S

Who is not sure or drives different accumulators please select the value 1.

• 3. Cutoff Voltage

Here the cut-off voltage for LiPos is set which prevents a deep discharge of the battery and stops the operation early.
For NiMH, please be sure to select option 1/disabled.
(1) Disabled
(2) Low (3,0V per cell)
(3) Intermediate (3,2V per cell)
(4) High (3,4V per cell)

A value of 3 or 4 is recommended here.

• 4. ESC Thermal Protection

If the overheating protection is activated, a thermal overload of the ESC is prevented by switching off the voltage supply to the motor. When the system has cooled down again, the power supply is switched on again. When the overheating protection intervenes, the LED flashes green ☼ - ☼ - ☼-.
Please note that the motor including ESC can become very warm because it often gets little fresh air because it is built.
(1) 105°C/221°F
(2) 125°C/257°F
(3) Disabled

A value of 1 is recommended here.

• 5. Motor Rotation

Here the direction of rotation of the motor is set, counterclockwise (CCW) or clockwise (CW).
(1) CCW
(2) CW

For the TRX4 we need value 2 CW.

• 6. BEC Voltage

Here you can set the BEC output voltage for the receiver. Attention who has no data from his receiver should set here 6 volts to exclude damage to the receiver. On the TRX with all original servos are also designed only for 6 volts.
(1) 6.0 Volt
(2) 7.4 Volt

The safe way would be value 1.

• 7. Drag Brake Force

Level 1-9
I recommend here value from 5 so that the vehicle also comes to a standstill on the hill, please try the value.

• 8. Drag Brake Rate

When you move the throttle from the throttle position to neutral, this value determines how quickly the brake is applied. This can be compared with a car if you press the brake pedal directly through the floor. A lower value lets the brake intervene more gently.
Level 1-9
I recommend a value of 1 - 3 so that the braking process remains realistic and the rear wheels do not lift off the ground during emergency braking.

• 9. Max. Reverse Force

Here we set how fast the vehicle can reverse.
(1) 25 %
(2) 50 %
(3) 75 %
(4) 100%

A reasonable value of 1 or 2 lets our crawler drive more realistically, since cars in reality are rarely 100km/h in reverse. But everyone must decide for themselves.
