If anyone is interested, there are a group of guys doing air racing and they have a class freeware T-6 with liveries available: http://www.fsxairsports.com/air_racing/classes/t6/
It's not as nice as the A2A T6 but is tweaked to match the racing T6s in performance and have realistic responses to the controls.
They use the Digital Theme Park TeamSpeak server and have a channel on there if anyone wants to meet up and fly races with them.
They also have pylon slalom courses, do short field landing (STOL) competitions, and such. The videos are old but to give a taste:

As an aside, they use boxed FSX but are now using PMEM's JoinFS to allow boxed and SE to fly together.
