RE: Pattern sequence designer?
Aresti 6 from Alan Cassidy is $100 US. It's designed for the IAC/IMAC types but Alan might be open to updating it for F3A. I know he did some custom work for me back when I was President of IMAC.
Interesting note Troy.. in IAC world competitions.. the countries pick select 1 maneuver to be included in the unknown maneuver list. Then the countries take all the maneuvers and submit an unknown using them, and then the international just selects the unknown to be flown from those submitted.
