Hi,
there are two small differences between the metal wings of the singleseater and of twoseater, that are the deletion of the wing balances and relative nervure under the wings, and the installation of 2 rocket rails instead of 4 under each wing, but it won't be a problem for a modeler.

You're correct about that Massimo - Eduard are nice enough to point that out in their instructions. I'm filling in the holes for the anti-flutter balances right now. One item that they don't have is the fabric-covered ailerons for the metal wing on the straight-winged two-seater, since they used the single-seater kit's metal wing. I'm probably going to leave mine as is - I don't think it will be that noticeable. I suppose you could reproduce the fabric-covered effect by carefully taping the ailerons to protect the metal areas and sanding the areas that were fabric. I might even try that.
Regards,
Jason
