RE: Ziroli DC-3
Not a dumb question,cause you need 2-3 degress of washout.Setup your panels on your bench so you have 0 degress at the root and 2-3 degress at the tip .Blockup the outer ribs accordingly so you have your correct washout and proceed from there.Make sure its correct before and during sheeting also because the sheeting should lock in the washout you built in to it.Hope that helps.
