Thats incorrect, Loop scavenged is a group of porting types that include schneurle porting. Usually original schneurle, and the more modern variants. What they call loop porting in the model world is reall cross flow porting. These names are from the pattern the flow makes when looking at the engine from the top looking down.

Opps, I see Bill had a similar post! Well I gues there are at least two who police improper scavenging names.
