I am in the process of putting together a Direct Connection 120 ultimate. The kit is an ARC and only came with a very basic direction book which has enough information to get me through the build, but it appears that there is another instruction book missing from the kit that tells what each part/number are used for.(There are a few parts which I have no clue what they would be used for). Does anyone have any information on this plane that could help me out?

Also they call the plane 120 size. The wing span is 56" which I believe is only 3" bigger than the 60 size Carl Goldberg Ultimate. I know that the Carl Goldberg ultimate flies nice with a Saito 120 or a 150. My second questiion is do you think that putting a Saito 180 in the Direct connection ultimate is Too much? After all I believe they are the same blocks on the 120, 150, and 180 with only a few ounces difference between them. Thanks.
