. Reviewer Andre Cliche says about the SPAD XIII, that it "looks like a museum piece. But imagine that you can fly this museum piece and feel what the WWI pilots felt when they flew their war machines." Reviewers Roy Beisswenger and Marino Boric wrote in a 2015 review, "the kit is very complete and builder-friendly, leaving you only the fabric covering, the paintwork and the fitting of the engine and instruments before you take off for your dawn patrol."Tacke, Willi; Marino Boric; et al: ''World Directory of Light Aviation 2015-16'', page 115.
