I'm guessing it will do wheelies on 2S. It's short and has a lot of power because it's brushless. On 3S it definitely will.
You could get a wheelie bar to protect the wing, but wheelie bars are annoying and get in the way when jumping. I wouldn't worry about scratching the wing because it will scratch when you roll too. Wings are cheap to replace anyway.
The physical dimensions are on Losi.com.
