Have a look at the two plan sheets on the [link=http://www.trentonrcflyers.com/pattern/patterna.htm]Trenton Classic Pattern Image Base.[/link] They show outlines for all ribs and formers and come with a bill of materials. The construction is fairly simple for this type of ship.

If I were you I'd order the [link=https://secure.rcstore.com/pcd/eServCart?iServ=MDY3QUo0NjYzMSZpVHlwZT1QQVRURVJO]Plans for both the Arrow and Atlas.[/link] That would show you the evolution of the 1975 World Champs winner into the 1979 World Champs winner. I'd incorporate the plug in stab from the Arrow into the Atlas using some [link=http://www.centralhobbies.com/control_linkage/adjustable_stab/stable.html]modern adjustable stab hardware.[/link]

Best regards.
