jt,you picked a great plane to start building with!!,it is very easy to build and a very strong plane the .46 will be right at home in it.
i have built about 5 of these planes for people and the only thing i do differently is to sheet the turtle deck with 1/16th balsa,this is not for strenght,it is for covering,i find the 1/4 balsa stringers tend to sag a little when covering with monocote.
