No.  For example, the FAI sets the 2-meter box for F3A (pattern) competition.

This corresponds to the FIA limit of 25 kg "unless otherwise specified."

Right.  Open records have one rule (wet); F3a has a different rule (dry).

55 lb. unless a special waiver is granted (with inspections) for a
heavier model.  I think the limit for the waiver is 70 lb.

It falls under the 25 kg rule.  Class F4C.

That's Section 4, Volume F3D.  Short answer:
2.2 kg to 3.0 kg (minimum to maximum).  They've
got lots of other rules to cope with, too.
