E-100 super heavy tank

Specifications:

Scale: 1/22

Drivetrain: 2 L motors

Turret traverse: M motor

Gun elevation: M Motor

Power supply: Rechargeable LiPO battery

Suspension: Torsion bars

History

Super heavy and prototype vehicles have always been interesting subjects for me, as I find they push the limitations of engineering. As usually each vehicle focuses on a large caliber armament mounted on a heavily armored hull, and to lower the ground pressure for these vehicles, a wide track is usually required as well. For the design of the E-100, a late war German prototype vehicle from the Entwicklung series

STRV.-103C

Specifications:

Scale 1/18

Drivetrain: 2 XL motors

Steering: L motor

Transmission selector: Servo motor

Suspension adjustment: XL motor

Dozer blade: M motor

Power supply: AA battery box

Suspension: Torsion bar

The Stridsvagn-103 (STRV.-103 for short) has always been a model that I have aspired to build.

IS-7 Heavy Tank

Specifications:
Scale 1/18th
Powertrain: XL motor
Steering: L motor
Transmission selector: Servo motor
Turret traverse: M motor
Gun elevation: M motor
KPVT HMG traverse: M motor
Control: 2 Sbricks
Suspension: Torsion bar

The complex curves and sharp angles of the IS-7 Soviet heavy tank proved to be one of the more challenging models to replicate in Lego form.

M4A2E8 FURY Sherman Tank

Specifications:
Powertrain: 2 XL motors
Turret traverse: M motor
Gun elevation: M motor
Engine: M motor
Control: Sbrick
Suspension: HVSS

Instructions available here

Redesigning the hull and turret of the Sherman tank proved to be a challenging task, as I wanted to include all of the basic functions of the tank, and include enough space for a detailed engine bay. The biggest challenge was incorporating all of the motors in a small space,

Churchill bridge layer

Specifications:
Powertrain: 2 XL motors
Main actuator: L motor
locking mechanism: servo motor
controlled by Sbrick

The Churchill AVLB (armored vehicle-launched bridge) is one of my most interesting and challenging models that I have recently built. The mechanism utilized to lift the bridge required a lot of development to ensure that it is structurally strong enough to lift and hold the bridge in mid air.

M18 Hellcat Tank Destroyer

Specifications:

Powertrain: 2 L motors

Turret traverse: M motor

Gun elevation: M motor

Suspension: Torsion bars

Controlled by Sbrick

This model was rather interesting to build, as I wanted to achieve the functionality of the open turret, and include the details of the turret's interior.

M8 Greyhound 6x6 Armored Car

Specifications:
Powertrain: L motor
Steering: M motor
Gun elevation: M motor
Turret traverse: M motor
Controlled by SBrick

This model is one of the more compact vehicles I have built, as the suspension utilizes a majority of the available internal space. The major difficulty when building this model was the mounting of the turret traverse and gun elevation motors. They had to be mounted between the first and second axles, as the space between there was taken up by the battery box and steering mechanism.
