I started flying this year and assembled my Twist ARF by myself with no prior knowledge of airplanes other than what I read on a few RC websites.
Read the instructions a few times before you begin and if you get stuck (as I did a few times) ASK, ASK ASK !!!!!!
There are plenty of folks on here willing to help and also at your local flying field !!!
Take your time too. There is no need to rush.
