Release on 1986 this Tamiya buggy is an UFO in the range of the manufacturer. The body was design by Takuya Yura from Moon Craft Designing (Mooncraft Co. LTD) who is knowing to work on aerodynamic for real racecar.
The Bigwig commemorated the 10 years of Tamiya in RC Hobby Industry.
This buggy borrow the gearbox of a Tamiya Boomerang but the chassis is different. It can mount a 8.4v battery without modification and a 540VZ Technigold motor with 14 balls bearing are include in the kit for better performance. Mine didn’t came to me with this rare Technigold motor.
The front is equiped with a steering rack. Very innovative and close to a real 1:1 car. But for this reason, it will be not efficient in time, even if a rubber reduce the dust inside.

The front drive train with the CVA shock is specific to the Bigwig.
The rear is the same as a Boomerang but Tamiya add more realism with engine head and exhaust.
Such as this Tamiya picture extract from a Guide Book with the sparks wires and scale details.
Radio installation !
The place for a radio equipment is big enough but it was hard for me to install those electronics properly. And doing like it mentionne in manual is an aberration. The antenna receiver is attach with all the power wires (motor and resistance).
Above all, power wires produce disturbance and can affect the signal reception. In most case with 2,4ghz it is not so also necessary

For example, this is how I manage to put receiver and the Sanwa Battle Champ ESC in correct place to avoid the problem.
Also ad a repro body from Penguin’s RC. The classic box art paint scheme is still georgeous. And the one piece Moon Craft wheel have an original design.
Morover, this buggy waiting to be test on a track, so to be continued…
