Hi Al,
I've got all of the Albatros's (or is that Albatros', or Albatri??)
Yes, the lower wing, especially the trailing edge, is significantly thicker on the later releases. Weight wise, the earlier planes are approx 450g, the latter approx 490g, although the fixed pilot will be part of the difference (20g ish). The John Jenkins Albatros weighs in at 390g. Its a shame the pilot in the later K&C plane isn't a removable figure. I would also have liked there to be a standing pilot to go with the aircraft. Overall though, pleased with them all.
Will we ever see a 'pusher'? I hope so!
Pete
