New to Eden Park Raceway

[freemundo]

Hi Guys,
Like most posts I am returning to 2wd RC racing after about 10 years away! OMG how much things have Lipo, brushless system 2.4mhz radio gear!
I wondering if someone could help with the following questions:
1. Are there any limits or classes for the 2wd drive class? Can you run whatever motor / lipo you want?
2. How long is the average race at EPR? 5 minutes?
3. How do I sign up for Eden Park Membership? I would like to complete some practice session before race day!
4. What turn brushless motor is being used @ EPR? 6.5? Any recommendations for a good brushless system?
