I 'lent' my copy of the Skytrace vid to someone ages ago and haven't seen it for a while. I presume it's still available - I got mine from Transair, and it looks like I may have to buy another
The vid is quite excellent if you are interested in the '52. Lots of internal and external aeros views, with mini cams mounted inside and out. There's also a complete viewing of Genna flying his display at Cosford a few years back.
