Avante

Avante is named after the first model put on sale with this chassis:

– Avante, model number 58072 put on sale in 1988 and available on the market until 1991,
– Vanquish, model number 58076 put on sale in 1988 and available on the market until 1992,
– Egress, model number 58079 put up for sale in 1989 and available on the market until 1991,
– Avante 2001, model number 58085 put on sale in 1990 and available on the market until 1994.

This chassis represents Tamiya’s clear attempt to regain the top position as a buggy manufacturer not only for fun, but also for competition use. By now, the Hot Shot chassis can no longer be developed any further:
– three models of the Hot Shot chassis have been released (Hot Shot, Super Hot and Hot Shott II), which differ mainly in their suspension system,
– the Boomerang chassis (Boomerang and Super Sabre) is an evolution of the Hot Shot family with a central shell retaining the two front and rear differentials. The central shell of the Boomerang chassis is open to improve access to the electronics,
– the BigWig chassis is the latest evolution that retains the two front and rear differentials of the Hot Shot, but is equipped with a further evolution of the open central tub. This model is known for its very aerodynamic body,
– the Thundershot chassis retains the basic concept by evolving the front and rear differentials

The Hot Shot project can no longer be evolved, so Tamiya’s engineering effort in designing the Avante chassis is truly remarkable, as it is intended to be a complete departure from what has been done to date. This is the main features sheet of the Avante 58072 model:

This project is so important to Tamiya that the Avante and Egress models are used for the most important pages of the Guide Book and catalogue: cover and second-third-fourth cover

These models represent a very important novelty for Tamiya, there are several advertisements that Tamiya or the various importers around the world have published in trade magazines; in the image below are examples for Avante.

In keeping with Tamiya tradition, the Avante chassis has evolved from the first to the latest model released for sale; Tamiya has not changed the name of the chassis, so to appreciate the differences it is best to start by analysing the characteristics of the Avante model 58072 and then focus on how the following models have differed.
The differences shown below are the main ones; the chassis are so different from each other that it is difficult to find common or interchangeable parts. The main common parts are:

– Parts A code 9005271,
– Parts B code 9005272,
– Parts C code 0005338 except Avante model which has code 0005328,
– Front hub carriers part numbers 5485007 and 5485008,
– Front axle part no. 4135026 and
– Rear axle part number 4135027.

Avante model 58072

The main features are:

– 1/10 body scale,
– 4-wheel drive on all 4 wheels with central differential,
– 4-wheel independent suspension with torsion bar on both axles. The suspension is one of the most striking innovations because it allows a lot of adjustment of the tie rods and arms. This was not possible on previous models,
– 4 newly developed aluminium shock absorbers Hi-Cap series. The shock absorbers allow very precise adjustment of their action,
– 4 identical wheels with special manual system for removing the rims, no tools required. There is an absolute first for Tamiya; the internal foam reinforcement,
– chassis formed by two plates made of F.R.P. which stands for ‘Fiber Reinforced Polymers’. as on the Racing Master 5…7 family of track models,
– Technigold code 50290 RX-540VZ motor mounted centrally and parallel to the drive axle to improve weight distribution,
– new Lexan body design that includes a shell that acts as lower chassis protection. The inclination of the Lexan rear wing can be modified to suit the circuit. The body design leaves little room for electronics, and in order to be able to install the receiver and speed controller, the most frequently used solution is to remove the driver.

The model suffers from sub-optimal dynamic behaviour:

– oversteer generated by the short wheelbase and the front wheels being too wide,
– the front suspension has insufficient travel to prevent the car from touching the ground,
– the front suspension system is prone to failure

Vanquish model 58076
The Vanquish model is a simplified version of the Avante that retains the general dimensions: for example, the wheelbase is the same.
The dynamic behaviour of the two models is very similar. The use of plastic parts has made the Vanquish more robust than the Avante. The main differences with Avante model number 58072 are:
– the Vanquish’s chassis is a plastic shell (highlighted in black in the picture) with the same measurements as the Avante’s chassis, which consists of two F.R.P. plates (highlighted in blue in the picture).
It is possible to equip the Vanquish with the twin-plate carbon chassis with accessory number 53038 “Avante Carbon Graphite Chassis Set”).

– The bumper on the Vanquish (highlighted in black in the picture) offers greater protection in the event of an accident, as it is larger than that on the Avante (highlighted in blue in the picture).

– The Vanquish’s suspension is independent as on the Avante, but with plastic lower arms and not adjustable. The picture shows on the left the K part which are the rear suspension arms of the Vanquish, the J part which are the front suspension arms of the Vanquish and on the right the D part which are the front and rear suspension arms of the Avante. The upper arm is adjustable in both models.

– Shown on the left are Vanquish’s plastic C.V.A. shock absorbers in the Mini version for the front suspension and Short for the rear suspension, and shown on the right are Avante’s aluminium Hi-Cap shock absorbers in the Mini 71 mm version for the front suspension and Short 92 mm for the rear suspension.

The suspension towers are made of F.R.P for the Avante model and are plastic for the Vanquish model.
– Vanquish has a nut (left in the picture) to secure the rim to the hub and not the quick manual release system found on the Avante (right in the picture). The Avante has an internal sponge between the rim and the tyre, which is not present on the Vanquish. The Vanquish’s front wheels are narrower than the rear wheels. This solution reduces oversteer, which is a dynamic characteristic of the Avante. The Vanquish’s rims have the same design as the Egress, but those on the Vanquish are white and those on the Egress are black.

– The steering system of the two models differs in the type of linkage used even though it uses the same principle.
On the left in the picture is highlighted the system of the Vanquish and on the right in the picture is highlighted the system of the Avante.

– the motor on the Vanquish is an RS-540S while the Avante is fitted with an RX-540VZ Technigold part number 50290

Egress model 58079
The Egress model is an improved version of the Avante that has a longer wheelbase and retains the modifications made on the Vanquish.
The dynamic behaviour of the two models is completely different.

The use of plastic parts from Vanquisg made the Egress more robust than the Avante. The main differences with Avante model number 58072 are:

– the chassis of the Egress is formed of two carbon plates (highlighted in grey in the picture), which follows the same configuration as the chassis of the Avante, which is formed of two F.R.P. plates (highlighted in blue in the picture). The wheelbase is lengthened to reduce oversteer.

– front bumper of the Egress is in common with the Avante model. Part G has the same code; in the Egress the rear bumper (highlighted in grey in the picture on the left) is not used while in the Avante the rear bumper (not highlighted in grey in the picture on the right) is used.

– The Egress’s suspension is independent as on the Avante, but with plastic lower arms and not adjustable, they are the same as those introduced on the Vanquish. The picture shows on the left the K part which are the rear suspension arms of the Egress, the J part which are the front suspension arms of the Egress and on the right the D part which are the front and rear suspension arms of the Avante. The front and rear lower arms of the Egress are the same product used in the Vanquish. The upper arm is adjustable in both models. The front and rear shock absorber towers are carbon fibre in the Egress.

– Egress has a nut (left in the picture) to secure the rim to the hub and not the quick manual release system found on the Avante (right in the picture). The Avante has an internal sponge between the rim and the tyre, which is not present on the Egress. The front wheels of the Egress have a narrower width than the rear wheels. This solution reduces oversteer, which is a dynamic characteristic of the Avante. The tread of the Egress has a new design.

The rims on the Egress have the same design as the Vanquish, but those on the Egress are black and those on the Vanquish are black.
– Egress has ball differentials (left image) while Avante has differentials with satellites (right image).

– the steering system of the two models differs in the type of linkage used even though it uses the same principle
On the left in the picture is highlighted the system of the Egress and on the right in the picture is highlighted the system of the Avante.

– titanium screws (they are an accessory for all other models, Hop Up part number 53009 “Avante Titanium rod set” and part number 53010 “Avante Titanium screw set”).
– the Egress motor is an RS-540 DynaTech 01R code Hop Up 53001 while the Avante is fitted with an RX-540VZ Technigold code 50290.
– No driver is provided.

Avante 2001 model 58085

The Avante 2001 model is an improved version of the Avante that has the increased wheelbase of the Egress and retains the modifications made on the Vanquish for the plastic parts.
The dynamic behaviour of the two models is completely different. The use of plastic parts from the Vanquisg made the Avante 2001 more robust than the Avante.
– The chassis of the Avante 2001 is formed by two F.R.P plates (highlighted in light blue in the picture), which follows the same configuration as the Avante’s chassis, which is formed by two F.R.P plates (highlighted in blue in the picture). The wheelbase is lengthened to reduce oversteer, echoing the shape and dimensions of the Egress chassis, which is made of carbon.

– front bumper in common with the Vanquish model.
– The suspension of the Avante 2001 is independent as on the Avante, but with plastic lower arms and not adjustable. The picture shows on the left the K part which are the rear suspension arms of the Avante 2001, the J part which are the front suspension arms of the Avante 2001 and on the right the D part which are the front and rear suspension arms of the Avante. The front and rear lower arms of the Avante 2001 are the same product used in the Vanquish and Egress. The upper arm is adjustable in both models.
The rear tower is made of F.R.P. and takes up the size and shape of those installed on the Egress.
The front tower is made of F.R.P. and echoes the size and shape of those installed on the Vanquish.

– The picture shows on the left the plastic C.V.A. shock absorbers from Avante 2001 in the Mini version for the front suspension and Short for the rear suspension, and on the right the aluminium Hi-Cap shock absorbers from Avante in the Mini version 71 mm for the front suspension and Short 92 mm for the rear suspension

– the Avante motor 2001 is a Sport Tuned Black code Hop Up 53068 while the Avante is fitted with an RX-540VZ Technigold code 50290
– Avante 2001 (left in the photo) features the hub of the Avante with the quick manual release system found on the Avante (right in the photo). Avante has the inner sponge between rim and tyre, which is not present on the Avante 2001. The tread on the Avante 2001 has a new design.
The four wheels on the Avante 2001 are identical in size as on the Avante.
The rims on the Avante 2001 are white instead of orange as on the Avante model.

– The steering system of the Avante 2001 is different from the system used on the Avante model: the type of linkage used changes even though they use the same principle.
The system of the Avante 2001 (left in the picture) is closely related to that of the Egress (right in the picture). The two plates highlighted in red change.

Re-release

From 2011 to the present day (2024), the Avante chassis has been used in several re-releases with a complete commercial proposition. The re-release models take the original Avante chassis with minor updates: for example, the mechanical speed control is abandoned in favour of electronic control.
The plastics used in the re-releases are different from those of the original versions, even the plastic parts undergo some small changes in shape. It is normal industry practice to make changes to improve plastic injection when reusing old moulds. Parts that have proven to be fragile and prone to frequent breakage in the past have been updated or changed.
