The Sherman is the newest radio controlled tank from Heng Long. This is the highest spec version with working smoke generator, sound effects and BB firing turret. And as if that wasn\'t enough it now comes upgraded with metal gear set, metal tracks, metal sprocket wheel and metal idler wheel. This famous World War 2 Allied USA tank is a great addition to the Heng Long collection. The ultimate radio controlled tank for every \'wannabe\' tank commander This tank is feature packed and the transmitter gives you full control. One stick allows you to move the tank in all directions including rotating on its axis and pivot turning. The other stick controls the turret allowing you to take aim by rotating it in both directions and also up and down. Once you have your target lined up, hit the fire button on the transmitter and the tank will fire a small 6mm plastic BB, recoiling and making a shooting sound as it does it. The sound system has a running engine noise as well as firing cannon and machine gun sounds plus more. The cool smoke generator actually produces a small cloud of smoke from the exhaust The tracks are independently powered by twin motors allowing the tank to tackle the toughest off road terrain. Unlike some cheap toy tanks, the tracks on these are made from multiple treads linked together and feature several shock absorbers on each side to give realistic working suspension. To top it off the tank has a highly detailed shell with authentic color finish, realistic attachments and commander figure.It\'s a fully functional model with many upgrades over standard 1/16th tanks. Most noticeable are the upgraded metal tracks. This is the metal upgrade version so comes with metal tracks, metal idler and sprocket wheel and metal gearbox which not only add to the realism but also makes it more reliable.
