This is an injection plastic and metal radio or remote-controlled military vehicle model.
Beautiful, complete RC set, immediately playable with the installation of 16 (sixteen) AA dry-cell batteries (sold separately) and the included crystal. Some minor construction work is required for adding the accessory parts, though the model itself is beautifully-painted amd marked. Have fun playing with the many gimmicks -- namely muzzle flash, barrel recoil, sound of the main gun firing, gun elevation and limited turret traverse. No BB ball firing unit or sophisticated IR battle unit is incorporated, but this RC tank will give a chance to the RC modelers to build up the bait for -- or adversary of -- 1/16 scale RC Tigers! One 27MHz crystal is included, but if you purchase additional crystals up to 6 tanks can be run simultaneously. Maximum operation range is 30 m; runs for 20 minutes continuously on regular alkaline batteries.
