Oscar,
As Steve kindly pointed out, there is an Australian Flying Corps Website with plenty of text, mindlessly boring details and profiles of aircraft.

The website has had a tonne of content contributed to it from forum members such as Andrew Smith, Gordon Branch, Killratio, Vin Ryan, Paolo Varriale and more recently Hannes Tager contributed his research on
German Aviation Reports on the non Western Fronts. So plenty of stuff there to go through.
There are also profiles of AFC aircraft, so depending on the aircraft you are modeling there are plenty of choices on the page.
