New PF Engine explained

Techbricks spend some time and engines on the new L and SV engines. These engines are introduced in the Lego set 9398 Crawler 4x4.

The L-engine is stronger than the M-engine but in a different smaller shape just 3x3 in stead of 5x5 for the M-engine.

The SV engine is a servo motor so will remember position and so can easily be used for steering.

However for much more details about the inner world and reductions of these engines read the blog on Techbricks.
