For those that say ''FAI does it that way'', well consider that FAI weighs helicopters in F3C with fuel or batteries and they have a 6.5kg limit.
When F3C went to 6.5Kg, did the cost of participating decrease? Did the number of participants increase?
Looks like they have a total of 9 registered for the Nat's this year...RCA has 104, second to Soaring with 132
