Over the past few years, quite a few local contests in both the USA and Canada used F4B rules for Sport Scale in lieu of the AMA or MAAC Rules Books.  The idea was to give the flyers interested in the national teams a chance to practice and prepare for the Team Trials and World Championships. 

While I had no intention of entering a TT, I was willing to put with the more complex rules if that was what the organizers wanted.  But now, the FAI has dropped the event due to lack of attendance at the WC, so there's no TT, no WC, and no need to practice.

So I suggest that local organizers take the FAI's lead and declare the horse dead, and go back to using the national rule books. 

While F4B rules are not exactly "unliveable", they are are outside the reach of our Contest Board system, and will effectively be abandoned by an international committee whose only surviving event is RC.  The F4B Rules are several times as long as the AMA Rules. 

This planet (Earth), could not come up with five flyers from five different nations who wanted to fly the event.   That says it all.  So let's not try to restart it by pushing it uphill.  Better to use AMA Rules or develope a new local event with more participation.

I guess, in theory, whoever hosts the 2012 WC could put F4B on the schedule, and it five nations sign up, it would be resurrected.  But considering the lack of participation when it was a "solid" event, it seems like the odds of that are slim.  Then again, maybe the 2012 WC will be at a venue where five nations are in easy range of surface travel and lightning will strike.

In the interium:

FAI scale rules are 82 pages long, of which 42 pages relate to CL.
AMA scale rules are 29 pages long, of which 14 pages relate to CL.
Furthermore, AMA rules are written in Yankee English by a committee of our peers. 
FAI rules were assembled by a multinational committee and translated into a convoluted version of The King's English that's not so easy to comprehend.

So I suggest that, at least until F4B gets back on the menu, we make life easy and use our own rules.
