Headache King of Cabs

I found this truck on Ebay and got it for just 45 Euros. Included were an extra set of bumpers and a 3300mAh NiMH-Battery pack. I stripped the chassis down and rebuilt it, flipped in a 21turn Graupner Eco motor and a Tamiya TEU101 ESC. The ball diff gave me a real headache as I couldn't make it stop slipping. So I took some parts from my Vanquish/Avante spare pool and modified a Vanquish gear diff to fit into the King cab's gearbox. Now it runs like hell.
