Today, we conducted an outdoor test of the K2 tank. Prior to going outdoors, the upper plate of the tank was installed to minimize the flow of dust from driving into the tank.
The attached photos show temporary work before going outside.

I share a short video of a tank going up a slope of about 40 degrees with a large gear ratio.

The K2 tank is currently manufacturing the exterior shape of the body, and after completion, the warehouse for operation and storage measured the weight of the 1/6 scale chieftain tank that was made in the past to check the performance of the newly purchased scale.

In order to check the performance of the newly purchased scale, we measured the weight of the 1/6 scale chieftain tank we made in the past.



The 1/6 scale chieftain tank weighed 144.65kg.

The K2 tank is currently producing upper hull work and side skirts that make up the exterior features of the body.

The steel parts that will make up the turret of the k2 tank have been outsourced and arrived.

Default Episode 28: Top Hull Work and Side Skirt Work

As I introduced earlier, we carried out the external work of the K2 tank's body this week. A variable turret ring was installed and tested.

I'll post the pictures about episode 28 and explain it.

After the last outdoor test, we prepared the work of making the appearance of the tank.

Use 1.5mm aluminum angles and aluminum panels. Unlike the main structural materials that use steel, the materials that make up the appearance due to the limit of weight are made of aluminum

First, secure the aluminum angles to the left and right sides to match the design length.

The aluminum angle was fixed with a bolt.

Prepare the caterpillar upper plate to be connected to the angle.

The connection between the caterpillar upper plate and one angle was fixed using a rivet.

Fix the upper plate of the caterpillar to the left and right sides of the tank body.

Fix the upper plate of the caterpillar to the left and right sides of the tank body.

Add a 3D-printed structure to the caterpillar upper plate fixing. Secure the side plate here. Fix with screws.

Add a 3D-printed structure to the caterpillar upper plate fixing. Secure the side plate here. Fix with screws.

Install an engine exhaust port at the rear of the left upper plate and a plate with an inspection hole at the upper plate.

Make a temporary fix on the left side of the panel on the right caterpillar top with a vice plier and fix it with a bolt.

The left panel size of the right caterpillar top panel is different from the last version, as in the real K2, and the main power control panel will be installed at the rear right.

The size of the left panel on the right caterpillar top is different from the previous version in the left and right as in the real K2. The right side is thicker than the left back furniture.

Secure the motor to the left and right to control the turret. These are geared motors.

This version is an outer wheel turret, so I'll try to position it first.

First, fix the body and LAZY SUSAN turntable ring first.

Bolt the turret outer wheel gear to the LAZY SUSAN turntable fixed to the body.

Check the position of the motor drive gear.

Consider fixing the hub of the drive gear and the motor shaft.

Consider fixing the hub of the drive gear and the motor shaft.

Position the drive gear and the shaft hub.

Weld the drive gear to the shaft hub.

Test the turret gear. This operation uses an electric speed controller for RC cars.

First, one motor is operated to install the opposite motor gear at an appropriate position.

Secure the opposite motor gear to the motor shaft.

Position the box for rotation test (see video)

Motor performance is also checked by applying resistance to rotational motion.

Secure the turret in the neutral position. The turret does not rotate freely due to the influence of the geared motor.

After the turret test, assemble the upper hull.

Complete the upper hull assembly and inspect from all directions.

When changing the design, check the bolt hole on the body that is missing from reflecting the change. Do separate drilling work later.

It is easy to install if the upper hull of the tank body is made into a single plate, but it is divided into a number of plates to facilitate accessibility for necessary detail lines and future vehicle inspections.

Prepare the side skirt work.

Print the side skirt fixing parts to the 3D printer.

Bolt the side skirt fixing part to the side of the K2 tank body.

Install the securing hinge on the side skirt. These hinge parts are also printed out with a 3D printer and secured with bolts.

Install the securing hinge on the side skirt. If necessary, check the fixture and location.

First, install the left side skirts.

Check the position of the back mudrest to connect to the last rear side skirt.

The way the back of the mudrest is fixed and operated is similar to the real K2 unlike the previous version.

Left Side Skirt Installation Completed

If the fixing pin is removed during use......

Open in a way that unfolds.

The 2nd and 3rd tier side skirts can be raised simultaneously when all fixing pins are removed.

If the fixing pin on the last plate is removed, the last side skirt and mudrest can also be checked.

Default Production of turret frame and recoil work of main gun

The turret's frame was constructed from the prepared K2 tank's turret structural materials, and the main gun was applied with pneumatic recoil.
The work video will be edited and shared on YouTube soon.

In Korea, the traditional holiday of Chuseok begins tomorrow.
I hope you all enjoy the rich autumn.

Regards,
Young

Has anyone else had trouble viewing this thread on your phone? Lately when I come here and click on "view first unread" it locks up my phone for a good 3 or 4 minutes. I think that's because there's just so many photos to load in this thread. It might be time to end this one and start a "Part 2".

And it just did it again when I posted above. The phone won't do anything for 2 or 3 minutes and then it acts like I restarted it. And this is the only thread it does that on. I think it's just because the threat has gotten so long and there's sooo much information that has to load that my phone just kind of freaks out.

There's something wrong with this thread that we didn't even think about. I'm sorry for the unintentional inconvenience. We will complete the K2 tank soon and then close this thread.

The turret production will be completed by next week, after completing electrical wiring work for headlights, signal lights, turret power supply and generator connection, various external details will be carried out, and finish painting before shipment, and this project will be completed.
And we will continue the upgrade process in the future by using the K2 desert version 1/5 scale RC tank completed in a separate thread.

For future upgrades, see
1. Engine Output 35CC -> 80CC Change
2. Change radio control mode (2 Stick -> 1 Stick Control)
3. Add main gun and turret stabilizer
4. Steel and metallization if plastic parts are required
5. This is a modified posture stabilizer, a feature of the K2 tank.
