About the Asiatam's Panzer IV hull, I must say its ok. The aluminium its very strong, the front rear sprochet and return rollers are correct, and the exhuaust may be the coolest part ever done for a RC tank.

But the no good things are that the upper and lower hull close system is bad designed and you have to do your own system or try to fix it, and the pin holes for the suspension are too small and you have to re drill them.
