First I agree with jjscott above, IF you want to jump back in with a scale build go with aTop Flight Kit, that being said, also agree with Jim that they are NOT what you want to start with for getting back to flying.
May I suggest an alternative since you like WW-I aircraft? Grab a BUSA Eindecker 90 (
