I have a set of plans for a Boeing F4B-4 and also its predecessor the Boeing F4B-1. With the possible exception of the ailerons, are there any differences between the outlines and wingspans of the two aircraft? I have the model plans for the wings of the -4 but the Boeing F4B-1 plans for the wings are missing. Would like to model both versions. Thank you, Skye
