(You need almost all parts that you see on image. Don't buy set with only gears!)

~104mm

~110mm

53-60mm

(I bought the springs shown in the picture, but they're too stiff. I removed some of the leaves and left only the two largest ones, but the leaf springs are still quite stiff. You can follow me or try finding a set of softer leaf springs. Shock absorbers are not necessary, as the leaf springs are stiff enough to hold the model.)

12x5mm Hex coupler 12428-0044 4pcs for rear axles + 2pcs for front drive axle.

(Make sure that you buying hexagons for WlToys axles! Standard Hexagons for typical 1/10 cars is not compatible with WlToys axles, because metal pins have different diameter.)

HOBBYWING QuicRun WP-1060

(Recommended to use this speed controller, because it pretty compact and easy fit into fuel tank v1)

10A 3S Mini ESC, Two way, no brake

(I am using:�- 1pcs for Dump bed lift motor

- 1pcs for a Trailer Dump bed lift motor

- 1pcs for engine imitation fan motor)

I am using Fly Sky i6 Transmitter + iA6 Receiver

My transmitter slightly modified. I will make video about modifications later.

For this model you need 3S LiPo battery.

Battery compartment size 125.8mm x 34.7mm x 26.6mm

Usually this is enough for 3S LiPo 2200-2600mAh battery, but I am get lucky to find 3300mAh battery. Sadly that seller run out of stock, therefore I can`t give you a link.�Pay Attention! Usually sellers writing dimensions of a battery, without including a wires thickness. So, if you see in the description, that battery length is 125mm, this battery do not fit! For this model you need a battery not longer than 118mm!

For model wheels installation you will need small bit for M2 nuts like on image

For assembly of some model elements, you will need long, thin screwdriver, like on image. + type, blade thickness not more than 5mm.�

Recommended to install an exhaust pipes now, because after installation of DC Motor, installation of brown part of the exhaust pipe will be impossible.

After installing a parts, it's recommended to add a glue into seam between parts. It make whole assembly more hermetic and prevent “air leaking”. Of course it's important only if you planning to use a smoke generator.

DC Motor and reducer assembly

To combine a motor with a reducer:�1) Remove mounting plate from reducer by rotating it clockwise.�2) Attach mounting plate to a motor, using M3x8 screws. Pay attention! Mounting plate have 4 holes, when motor have only 2 holes for screws. It`s mean that this is possible to install motor in two position, but only one correct! See correct assembly on right image!�3) Attach a motor to a reducer.

Gear shifting lever should be on left side and perpendicular to a wires pins!

For screws recommended to use a thread glue!

Motor-reducer preparing

M5x25 with LEFT Thread

To make an output shaft for the motor, screw an M5x25 screw with LEFT THREAD into inner hole and then cut a screw head. Leave approx. 7-8mm of screw.

Cab parts pre-assembly

Parts was separated to optimes them for printing and also to have possibility to print them with different colors. As I saw on photos of real truck: grill usually have silver color, when outer parts can be Silver, White or same color as a Cabin.

Glue a towing yoke into a front bumper or use a soldering iron to weld it to bumper from inner side.

Cab front side assembly

In my opinion, for visible sides of the Cab, better to use socket button head screws. But any head type screws can be used.

After printing, this hole will be closed with one layer of filament. This is necessary to improve the quality of the surface that was turned towards the supports. So, just clear a hole with a knife.

I only had black screws. I think silver screws should be used on silver parts. I used a silver chrome marker to paint the screw heads before tightening them.

Glue a headlight glass into headlight body, then use a soldering iron to weld it to fender from inner side. Put a 5mm White LED into a headlight.

Glue an orange reflector to a fender.

For printing lamp glasses, you can use transparent PETG filament. You can find them in 10 or 20 meters to save money not buying whole roll.

You can install the bullbar now or at any time later. It might be best to install it at the very end to avoid accidentally breaking it.

Put 3mm Orange LED and then glue reflector and it`s guard above.

Instruction how to make diy Light module, based on Arduino Pro Micro, to control all these LEDs, will be added later.

Cab top part pre-assembly

There's not enough room here to use any fasteners, so the part must be glued or soldered. It's recommended to sand the surfaces before joining.

Lifehack! To make connecting the parts easier, I attached them to the bottom of the cabin. However, the other parts of the top of the cabin must be attached before joining the top and bottom! So, I connected these parts to the bottom of the cabin, soldered them from the inside, and then removed them.

Cab windows gluing

To easily making windows:

1) Place the window frames upside down.

2) Coat them with glue.

3) Place a 0.5mm thick transparent sheet on them.

4) Wait for the glue to dry and cut out the windows.

5) Glue the windows into the cabin.

I used cyanoacrylate glue. Any traces of it on the part can be removed with lemon juice. Lemon juice works slowly, so several cleanings may be necessary. It is also recommended to clean the part immediately after gluing. I tried cleaning the part two days after gluing the windows, but I couldn't completely remove the glue residue.

Roof assembly

Put a 3mm orange LED into running light body, then glue an orange reflector to it.

You can fix the silver parts in the roof by melting the protruding elements with a soldering iron.

For printing lamp glasses, you can use transparent PETG filament. You can find them in 10 or 20 meters to save money not buying whole roll.

These roof LEDs can be connected in parallel with the headlight LEDs. Then they will always light up when the headlights are on.

Dash panel pre-assembly

Glue all small elements to a Dash panel as shown in the image.

Colored cylindrical elements in the dash panel is a pieces of filament.

Initially, I am designed this tumblers as 3d printed elements, but they a became very small and not easy to use them. So, I just use a thick wire to make these tumblers.

If you smeared glue on the panel while gluing the parts, you can coat the entire panel with glue. The result won't be perfect, but it's better than glue stains.

Cabin interior assembly

Glue the parts together. After printing, you'll have a straight rod-shaped center section. After gluing the parts together, heat the part and bend it as shown in the image.

After assembling the gear shifter, screw it and the center console into the cabin. Use M2x6 screws from the underside.

It is recommended to use a little glue to ensure a more secure connection of the parts.

After printing, these holes will be closed. This is needed to optimize part for printing. To clear hole, you can use 4-4.5mm drill bit.
