Thanks!
Its no problem to get Remote control unit here and i have charger and battery from a different project.
For the electronics i tend to the clark TK60 or maybe ElMod... have to check where i can get the most realistic abrams sound.
I asked at DKLM and they told me that they can also offer me the turret of heng long tank.
Still have to check if this would be inside my budget but it sounds good.
Lower hull alone should weigh about 6.5 Kg
