my Excalibur arrived yesterday and I can only echo what John Holiday said. Walt's kits are probably the zenith of the kit makers art .The laser cutting is absolutely perfect and you could probably shake the parts free from the sheet wood. Plans are perfect with a check of a few parts to confirm accuracy, but Walt has always been a perfectionist about plans and parts fit.
If you have never had one of Walts kits your overdue to have one that could very well change your opinion of what a kit really is, or should be.
