Nic, are you able to mark off where all the spars, formers and the aluminium for the wings are supposed to go? Because I see that the plan wilmracer got have the indications for where each spars and formers are going to be. As for the aluminium spar and dihedral gauge, I'm not quite sure where is it in the plan. Still studying the plan right now... Will start building once I have a clear picture how the plans goes together.
