Does anyone know where I could find stats/specs for the CAC LMS? I'm curious about engines, weights, dimensions!

LMS?  I might be able to assist but need to clarify exactly wha you are referring to.

The Commonwealth Air Corporation LMS Light Military Transport:

Gentlemen, can I press upon the forum for information (or an educated guess) as to what 'year' the Commonwealth Aircraft Corporation (CAC) CA-31 might have entered production, had it been politically and militarily supported in Australia.

HSA's Hawk went from private venture studies in 1968 to an AST in early 1970, initial contract in 1971 and then March 1972. Prototype flew on  21 August 1974  and entered service in late 1976.

CAC had much less experience than Hawker Siddeley, and the CAC-31 was technically much more ambitious. Can't see it taking less time that the Hawk.

CA-31 studies were from 1965, submitted in 1966 to a requirement, but even given a contract in 1967 I'd guess first flight would probably no earlier than 1974 and service entry 1978?

I only saw one file on the CA-23 at the Melbourne office of the National Archives of Australia. Unfortunately I missed the "Appreciation of Fighter CA 23 [1952]" from the private papers of H.P. Breen. The rest are in Canberra, including the very interesting looking Cabinet paper "Production of two prototypes of a long range all weather attack fighter aircraft CA 23 : Agendum Number - 129/1953 and Attachment : Date of Meeting - 20 August 1953". Which at two folios thick could be a gold mine. Alas this means I'll have to make a visit to our nation's capital.

I've data captured the 'Low speed wind tunnel investigation on the CA-23, a twin seat all weather fighter aircraft', D A Lemaire. This report details effects of various adjustments to the wing planform, flap size, with or without tails, dive brakes, etc. Primary purpose of these tests, carried out in Feb to Aug of 1951, were to explore the low tailplane position. Original position was a high T-tail, then to a position below the fin and both were destabilising.

Looks a lot like British reports of that era, though the typo in "Resticted" is funny.
