Pajero

Tamiya released only one model equipped with the PAJERO chassis and obviously kept the name: model number 58044, which went on sale in 1984 and was available on the market until 1986. For Tamiya this is the second time, after the B2B Sidecar model 58017, that it has released a chassis available on the market with only one model.
It is a model designed to perform stunts, there are two tricks devised by Tamiya’s designers: the battery is installed cantilevered over the rear axle and an arm installed on the differential case equipped with a fifth wheel to maintain balance when the car is wheelie.

Tamiya reproduces the off-road vehicle that Mitsubishi developed as a means to participate for the first time in the 11th Paris Dakar in 1983. Mitsubishi chose the category in which off-roaders are closely related to the production model in which it is not possible to modify many parts such as the transmission, which is the same as the production model. The model chosen to participate in the competition is the first 4×4 designed by Mitsubishi that is offered worldwide under the name Pajero/Montero. At the end of the competition, the Pajero took first and second place in its category, finishing eleventh overall.
Compared to the original model, Tamiya added the roll bar with the two lights and removed the additional headlights installed on the front bumper. There are several advertisements that Tamiya or the various importers around the world have published in trade magazines, in the image below is an example.

This model was a very important innovation for Tamiya and there are several pictures that Tamiya published in Guide Books from the 1980s.

Tamiya included an alternative body colour for the Pajero in the 1985 Guide Book.

These are the main features

– the central frame is a plastic material (ABS) shell to protect electronics from wheel splash,
– an oil-free spring-loaded shock absorber for each of the four wheels,
– the front suspension is independent,
– the rear axle is rigid with differential,
– a fifth cantilevered rear wheel,
– the electric motor is the RS-540S and
– the four wheels are isodiametric, reproducing the tread of a real car.

The PAJERO is an evolution of the GRASSOHOPPER chassis that is sold on The Grasshopper model 58043 and The Hornet model 58045. The Grasshopper and Pajero chassis share the front suspension system with its A-arms and the rigid axle rear suspension system on which the motor with the differential case is installed.

There are also other small parts in common, in the pictures below on the left the Grasshopper chassis and on the right the Pajero chassis:

– brackets for the steering and mechanical speed control servos,

– the U-shaped support for the mechanical speed control system,

– the two attachments to the chassis for the rear suspension system which are the same for the Pajero and The Grasshopper.

The biggest differences are in the central ABS chassis which is completely different from the Grasshopper and Pajero chassis, in the pictures below on the left the Grasshopper chassis and on the right the Pajero chassis.

The four spring dampers are different between the two models.

Evolution

The Pajero chassis has been evolved into the Lunch Box chassis that we find in only two models: Lunch Box model number 58068 and MidNight Pumpikin model number 58070.
This new Lunch Box chassis has in common with the Pajero chassis and the Grasshopper chassis:

– rigid rear axle with differential,
– independent front suspension with A-arms
– U-shaped supports for the mechanical speed control system and
– supports for the steering and mechanical speed control servos,

The central ABS shell of the Lunch Box chassis is an evolution of the Pajero chassis shell modified in some of its parts. The most obvious modifications are at the front, in the pictures below on the left the Pajero chassis and on the right the Lunch Box chassis starting from the front and moving towards the rear:

– front T-attachment to lock the body onto the chassis for the Pajero model, which is completely missing in the Lunch Box chassis; highlighted in green in the picture.
– shape of the wing that in the Lunch Box does not extend to the front as on the Pajero; the wing of the Pajero is highlighted in red in the picture
– attachment to the shock absorber frame which is recessed in the Pajero and is raised in the Lunch Box to install shock absorbers with greater travel; highlighted in blue for the Pajero and in blue for the Lunch Box,

– there are other small modifications from the Pajero chassis to the Lunch Box chassis that were necessary to install the Lunch Box and Midnight Pumpkin body. In the picture the Lunch box hooks are highlighted in yellow and the Midnight Pumpkin hooks, which are absent from the Pajero chassis, are highlighted in black.

The Lunch Box chassis is not designed to perform stunts, so the batteries have been moved from the rear overhang to the lower central part. This modification results in a different battery carrier system. In the pictures below on the left the Pajero chassis and in the middle picture and right the Lunch Box chassis.

The modification to accommodate the battery in the lower part of the centre shell also involves a difference in the two attachments for attaching the rear axle to the chassis. The pictures below show the Pajero chassis on the left in blue and the Lunch Box chassis on the right in green.
The rear system that connects the rear axle to the chassis is different between the two models. In the Lunch Box the point at which the rear axle hinges to the chassis has been modified (highlighted in blue for the Pajero and part in red for the Lunch Box in the picture). Attaching the Lunch Box to the chassis allows a degree of freedom to be added to the movement of the motor – gearbox – rear axle system; a 95mm long 4mm diameter pin has been added (highlighted in orange in the image) that works inside the two plastic joints (highlighted in red in the image) modified to house the axle and counterbalance springs (highlighted in green in the image). In the Pajero the rear system can only rotate, in the Lunch Box it can rotate and move vertically cushioned by two metal springs. In the picture below the free movements that the rear system can make are highlighted by the dotted arrows; the rear system of the Pajero can only rotate, the rear system of the Lunch Box can rotate and move downwards and upwards, absorbing bumps better.

– Although the rear drive system and differential box is the same, the way the motor is installed changes. In the pictures below on the left the Pajero chassis and in the middle and right the Lunch Box chassis with the spacer highlighted in red.

The four spring-loaded shock absorbers and the arm installed on the differential case with the fifth wheel are different between the two chassis.

Re-release

The Pajero was re-released for sale in 2011 using the Lunch Box chassis, but with a new designation: CW-01. Aesthetically the body is identical, the modern version can be visually recognised from the original by the different wheels used, which are now larger with V-shaped treads.
