Hi
I take my son down to Mansfield and will be there today, we are new also it is his 4th time but I will try to answer your questions as best I can.
1. As far as I am aware you are allowed to race 3 times without membership.
2. There are all skill levels there and quite a few newcomers.
3. They race 2 and 4wd at mansfield but not sure if you can enter both.
4. I think it finished around 6 last week with the doors opening at 2.
Hope those answers helped, I am sure one of the more senior members will give you more comprehensive answers but I thought I'd answer you in case they don't pop on
