Aftermarket reed petals, IJSBA
Petals and cages are governed separately, and the difference decides whether a kit is legal.
Where it stands, class by class
12 classes, grouped where the same rule gives the same answer rather than listed one by one, because an answer that holds for a class usually holds for every class that borrows its rules.
What each answer below means
- Not permitted, not listed in the rules
- Treat it as coming off. The class requires the craft to stay stock except where the rules allow otherwise, and this part is not on the list, so this is our reading rather than a rule we can quote at you.
- Legal
- Keep it. The rules permit this part in this class.
