In terms of scale accuracy, it's better than the Flair Puppeteer, but still sport scale (most noticeable in the typical fat BUSA airfoil). If you want a truer to scale Pup kit you should check out CDScaleDesigns 1/6 scale Pup kit or Bonnington's 1/5 scale plans, which can be ordered with parts. The main draw of BUSA kits is that they are "easy to build" so about like the Flair WWI kits.
