Avis's tiny Bristol Racer. Although it was technically advanced for it's time (retractable undercarriage, streamlining, monocoque monoplane, estimated 220mph top speed) it was ultimately unsuccesful. Designed to showcase the Bristol Jupiter engine in air-races it suffered from poor handling due to overlarge ailerons which damaged the wings in flight! Subsequent modifications helped but despite being enterred for the 1922 Coupe Deutsch de la Meurthe competition in France it wasn't ready in time. It only flew 7 times in total.
Quite a nice kit to build, added a few extra details (pitot tube, bars on undercarriage). Rigging is stretched sprue. No real issues with fit - some sanding needed on joins. the interior is quite detailed (for 1/72) and just about visible through the wheel wells (although not clear in the photos). There are a reasonable number of reference photos to help. The kut decals are excellet and they provide spares. there where two windscreens too.
Main issue that everyone mentions is the undercarriage - it isn't clear at all exactly how it fits (and the photos of the real thing are too dark to see).
