I've got all 3 tanks from firebox.
The "problem" (i find it more real) with those tanks is that in order to have them turn. It will first move the turret to the right for them to turn right. When you want to go strait the turret must center first. The same goes for left turns. First the turret must point left for it to move left It's because they only have 2 motors. One for the turret and one for the drive train. So you can't run strait and take a left turn without stopping first and let the tank rotate the turret to the left or right first. They are not proportional. One speed only. They are a tiny little bigger than the Digi ones. They aren't cartoonish like digi but more real proportioned. Not as detailed like the digis but the wheels pivot like the real ones, simulating suspension. The submachine gun (which i will mod) is a red led which flashes and gives a ra-ta-ta sound while pushing a button on the controller.
Same goes with the main gun. The tank will recoil in a much more real fashion than Digi. A very short recoil and back with a gun sound. The nice thing is the games you can play. One game will let the tanks fight each-other automatically. They seek each-other out by infrared signal. One major disappointment was that they aren't compatible with the digi signals or visa versa. I tried. I think they are very nice tanks. Very different than the digis which have more steering control but i find the firebox tanks more real, more authentic. The funny thing is that they sound exactly the same as my gun sound mod i did on the Digis. The components are also the same! Had the right idea i guess
