LRP ZZ.21C Ceramic Square Stroke Nitro Competition Engine

The all-new lrp ZZ.21C Ceramic Square stroke engine exclusively made by O.S. Engines is the successor of the internationally very successful ZZ.21.Ceramic Long Stroke. More precise response characteristics in the lower RPM range and less fuel consumption were the goals in the improvement of the power aggregate.

This could be successfully implemented with a square stroke design and a special, new developed crankshaft. The 14.0mm strong crankshaft has a DLC coating as well as a silicone insert. It is also precision-balanced just like its predecessor and works very smoothly in combination with the ceramic bearing.

Due to the reduced fuel consumption, a longer run time and a more controllable power delivery could be realised.
