 Product Description

Having a forerunner with this vita, it’s hard to impress: the ZR.21X was - and still is - extremely successful in racing all over the world! But also the brand new ZR.21X Spec.2 shows its colors. Many decisive features have been refined and upgraded. The new Spec.2 version is a completely new nitro engine and has the potential to be the future 1/8 Off-Road star!  
At first sight it is obvious, that not only small things have been changed. For a significantly better heat dissipation the upper, blue cooling fins are turned a little upwards. Even more decisive for the improved cooling and higher efficiency of the engine are the cooling fins directly at the burn room. A genius and revolutionary idea.  
The new XTEC thermal protected WorksTeam 14SV-2 carburettor with changeable 6.0 and 7.0mm venturi inserts provides a smoother performance of the ZR.21X Spec.2. Instead of the usual aluminum the carburettor is made from the more rigid aluminum alloy Ergal. The result is a running smoothness, that generally can only be found in much bigger engines.
