F.A.V. stands for Fast Attack Vehicle and is named after the first model released for sale using this chassis:
– Fast Attack Vehicle model number 58046 put on sale in 1984 and available on the market until 1986 and
– Wild One, model number 58050 put on sale in 1985 and available on the market until 1988
These two 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 is an example of an advertisement for Wild One.
The main features of this chassis are:
– front bumper in common with the ORV chassis; code number SP-5208 or 10445007 for the bumper only,
– independent spring-loaded front suspension.
– Plastic chassis shell to which the front bumper, front suspension, drive system and rear suspension are attached. The lower shell is an integral part of the bodywork. The roll bar effectively protects the car during accidents and rollovers,
– rear-wheel drive with independent rear suspension system with shock absorbers; the gears, differential and hexagonal-head rear axles are the same as on the ORV chassis. Gear and differential code number SP-5305 and rear axle code number SP-5207,
– RS540S electric motor
The main differences between the F.A.V and Wild One are:
– different front suspension tower; highlighted in brown for the F.A.V. model and in red for the Wild One model,
– The four plastic shock absorbers of the F.A.V. model are oil-free and are the same as those of the Grasshopper. The four aluminium shock absorbers of the Wild One model are equipped with oil. Left front shock absorber of the F.A.V. and right front shock absorber of the Wild One,
-the battery locking flap has evolved from the F.A.V. to the Wild one; in the picture on the left the flap for model 58046 and on the right the flap for model 58050. In normal use the version for model 58050 hardly opens, while the version for model 58046 opens accidentally during or after a jump.
-The bodywork and friver of the F.A.V. model are made of styrene and are bolted to the chassis pan. The bodywork and driver of the Wild One model are made of Lexan and are secured to the chassis with clips. The F.A.V. solution of screwing the bodywork to the tub guarantees greater rigidity than on the Wild One. Rigidity that helps in jumps and makes the model more robust.
– The chassis tub has undergone some modifications from model 58046 to model 58050. The bodywork of the Wild One is made of Lexan and requires fixing points with clips. Three towers have been created to house the screws for the body clips (highlighted in red the single front tower and in orange the two central-rear towers) and the tower to house the screws for the door clip that locks the battery in place (highlighted in green).
– rims and wheels of the Wild One are larger in diameter and are the same as Fox model number 58051, but white.
– The different shape of the rear rims changes the shape of the hub used to lock them to the axle. On the left rear axle system – rims of the F.A.V. and on the right rear axle system – rims of the Wild One,
For the Wild One model, part A7 is available to install the SP-5120, SP-5122, SP-5153, SP-5156 and SP-5183 accessory tyres,
– the F.A.V. model is equipped with side bumpers.
From 2011 to the present day (2023) there have been several re-releases of the F.A.V. model:
– model number 58496; offered for sale in 2011,
– model number 57828 ready to run factory assembled, complete with remote control, battery charger and battery; offered for sale in 2011
– model number 58539 in “Shark Mouth” version ready to run factory assembled, complete with remote control, battery charger and battery; offered for sale in 2012
– model number 57842; put on sale in 2012,
From 2012 to the present day (2023) there have been several reissues of the Wild One model:
– model number 58525; put on sale in 2012,
– model number 58695; put on sale in 2021: this model has been enriched with several metal-plated parts (parts A, E, G which are differential box, front and rear suspension arms to which the 4 rims are added) and different graphics such as the “BLOCKHEAD MOTORS” sticker designed by Jun Watanabe. This is a version that has some success as it is aesthetically pleasing,
– model number 57932; ready to run factory assembled, complete with remote control, battery charger and battery put on sale in 2022.
There are differences between the re-releases and the original models, the most obvious being:
– the re-release’s shock absorbers are different in shape from those of the original model, furthermore in the F.A.V. re-release the shock absorbers are equipped with oil,
– the speed control of the re-release is electronic, whereas the original models have mechanical speed control with resistance,
– the two rear axles of the re-releases are no longer hexagonal-headed as in the original version, in the modern version they are spherical-headed and pivoted. On the left the original model and on the right the re-release.
– there are small differences in the chassis of the two re-release compared to the original version. Some differences are limited to the colour of the parts. For the re-edition of the F.A.V., the chassis tub is printed in a colour that appears to be a dark yellow while on the original model it is brown tending towards the colour of sand. The chassis tub of the re-release and the original Wild One is printed in black. For the re-edition of the F.A.V. the D parts (side bumpers, battery door locking tab, machine gun and battery door) are printed in black while on the original model they are brown tending to the colour of sand. For the re-edition of the F.A.V. the roll cage is printed in black while on the original model it is brown tending to the colour of sand. The roll bar on the re-edition and the original Wild One is moulded in red. Other differences are in the shape of the components: the chassis tub of the re-releases for the F.A.V. and Wild One model is an evolution of the original Wild One: there are the three towers for the clips of the Lexan bodywork of the Wild One and the tower for the clip for the battery door. These towers are simply not used if the styrene bodywork of the F.A.V. is installed. In the image below the detail of part A of the original model is highlighted in red and the same detail of the re-edition in blue; in the re-edition a slot for the battery cable has been cut out of the left side bulkhead.
– the rear arm supports are reinforced on the inside and the material seems to be different: it appears more flexible
– for the F.A.V. model, the shape of the battery door has been retained; to prevent accidental opening, two clips have been added in addition to the D2 lever. The installation of the clips involved a modification to the frame
