[NSRCA-discussion] Masters 2009: Two 2/2 reversed

[richard wallace]

Great catch; I didn't find the maneuver description when I looked at the
rulebook earlier. Always in the past the rule book had the maneuver
descriptions in alphabetical order by maneuver name.

Wonder if it would be possible to fix the RC Aerobatics rulebook so that the
maneuver descriptions appear  in alphabetical order as before? I'm not sure
it's reasonable to make guys (esp in the heat of a contest) read the whole
list to find stuff tacked onto the end of the descriptions in no particular
order.... esp when using  a paper copy on a flight line and not an
exectronic copy on a computer...
The thing should be a usable reference whether in paper or electronic form,
and that seems to imply find-able details...
