See
http://www.wiki.luftwaffedata.co.uk/...itle=Downloads and look for The Blitz - Heinkel's Elegent Trendsetter.
This download contains an article on the He 70 and its derivatives. This article first appeared in Air International of Feb 1975. The artical contains three view diagrams (including a head-on view), a cut-away and is 9 pages long.
Hope that this helps.
