LRP ZR.21X Spec 2 buggy engine
LRP have released their ZR.21X Spec 2 buggy engine, which is a completely new nitro engine compared to the previously available version. For a significantly better heat dissipation the engine received a new cooling head with tapered fins, as well as a finned combustion chamber to keep the temperature of the glow plug in check. The new carburetor feature changeable 6.0 & 7.0mm venturi inserts and instead of the usual aluminium the carburetor is made from the more rigid Ergal alloy, the result being much smoother running.
