Narrative:

Flight from san to hhr when a friendly socal controller called to inform us that we were under class B airspace and speed restrs apply. Yikes! This was our first time into hhr and we had spent some time looking at various parts of the flight but not the class B airspace. Now you can say that the lax class B airspace is both large and not easily defined, however, the honest truth is that we hadn't really looked. We always fly under IFR rules and have been lured into thinking that we don't need to be concerned with class B airspace, which may be true for entering the area, not for speed underneath. In talking to the rest of our pilots, most are vague at best concerning the size and altitude restr for the various class B areas. After relating my little story this is a condition that will not exist any longer.
