Hi there Ken.... I see that Bill has answered your questions above....so no need to repeat.
The 2012 Official Basic/Sportsman/Intermediate/Advanced sequences are now up on the IMAC website on the front page. http://www.mini-iac.com
The Basic sequence takes approximately 5 minutes to complete so with a 10 minute gas supply, you will be good to go. In Basic, you will be able to fly any aircraft, so you don't need to purchase or build a different plane from what you now fly. If you take a look in the training section, at the lower part, you will see information on what the Judges will be looking for in the Basic sequence. We are presently working on the 2012 sequence Judging Presentation for both Basic & Sportsman & as soon as these are completed, they will be published on the IMAC site in the same place under Training.

Hope to see you flying on the IMAC circuit soon.
Best Regards,
Wayne (Matthews)
IMAC President
