RE: wanting to start questions
I second all that others have responded with. I flew my first contest over this past weekend and had a lot of fun. I went in with no expectations and viewed it as a learning experience. I went by myself and had no problem finding experienced pilots to call for me and offer lots of pointers/tips. Met some really nice folks and learned a lot. One thing I did find though is that some members of my club compliment me on my flying and I thought I was a pretty smooth flier. I found I wasn't as smooth as I thought. I'm not saying this to discourage you, just saying that IMAC is a fantastic tool to improve on what you have. I walked away with a multitude of useful information to expand on after just one contest.
As a side note, second place went to a small electric Extra that was probably around a 60 inch wing. So to answer your question, electrics are no problem in basic. Do it...you won't regret it.
