description on model: it comes separated you have to put the wheels the tank turret and tank gun on it is not put together like shown in pictures or else it wouldn't move like a tank. description on tank: It's a ww2 Russian tank that is one of the fastest and can run without tracks so I made it without track like a real bt-7. what you can customise with this: you can put your own tracks on but it doesn't have moving front and back wheels the only moving ones are the road wheels so you may have to put some tape on the front and back wheels so the tracks can just slide away from those none moving wheels you can also but a different head for the bt-7 if it is the same size as the bt-7 circle that fits to turn the tank head.
