From Tamiya's website:
"The British Chieftain tank first went into production in 1963 and had an intimidating 55 caliber 120mm rifled tank gun which was built for the purpose of knocking out Soviet tanks from a range of 4000m. The Chieftain's defensive abilities were also impressive with 150mm thick front armor plating. It was powered by a Leyland 19,000cc engine which pumped out 750hp for an on-road top speed of 48km/h. From the first Chieftain Mk.1 to the last Mk.12, approximately 900 units were manufactured."
Tamiya's original 1/25-scale kit of the British Chieftain was released in 1967, and now it's back as a fully operational radio-controlled model kit! A personal favorite of Tamiya chairman Shunsaku Tamiya, this classic kit has been resurrected with the the latest in miniaturized RC technology, with the drive gearbox and all-in-one turret traverse/gun elevation components pre-assembled and ready to install. Using the supplied 4-channel control unit, you can drive forward and backward, turn left and right, or pivot on the spot. The turret rotates and the main gun elevates and depresses. The suspension is fully operational and the individual link tracks with rubber road-use pads come completely assembled. Will require four AA batteries and one 9-volt battery for operation (batteries not included). Measures 42.4cm (16.7 inches) long when assembled. Considering the collector's prices the original Chieftain kits command these days, this new RC release is indeed quite the bargain. Nice to see an old friend like the Chieftain back again, more spritely than ever!
