Venturi and muffler rules
A couple of weeks before the World Champs in France the Chairman of the C/L Subcommittee and the F2D Judges Group sent out a document with
Technical Rule Clarifications for F2D.
This document had a new and radical interpretation of the rules on checking the size of the venturi and mufflers.
This document resulted in some debate on the internet and at the start of the competition in France.
Some pilots even had to make drastic changes to their engines right before the competition to fullfill the rules.
I found this conflict in the interpretations of the rules very strange. None of the pilots has any interest in changing from the normal "low tech" inspection
to a more restrictive "high tech" inspection. Only the organizers insisted that all engines should comply with their new and extreme interpretations of the rules.
I think that all pilots at the World Champs in France learned that it is not enough to think you know the rules and just do as we used to.
After all the trouble in France we have learned that we must be prepared for even the most extreme interpretation of the rules.
This was a good reason for taking a closer look on the 2009 shut-off rules.
