No where on the box does it say what scale these are but looks like they are 1/48.
I am low on time rite now as I have a (Honey due list) to perform today and will add to this as time permits.
Main features of these VS Battle tanks are..
2.4 GHz
lipo powered
Battle score system
Long range for both RC and IR
1 charger does both Tanks at the same time.
Only requires 4 AA batteries for the Transmitters.
1/48 scale so they are easy to store when not fighting a war.
Simple to use. No special training required. My wife likes these and she often wins the battle!

Very durable. Sprockets have slip clutch to prevent damage to gearbox. Great feature if your battle is on carpet.
The electronics including IR Battle system are in the Turret and are very small 2.4GHz tech. The hull is empty except for the motors and wiring to the Turret.
