Oldm8 as far as I know, there is one Legacy close to flying in Australia with another kit on the way. The aerofoil is completely different to the Lancair IV & Lancair 200-360 series. It is a much more forgiving airframe. Having said that, I must agree with other posters in saying that you should be experienced & current before flying these high performance aircraft. I have over 300 hours in Lancair IV's including 4 first flight test programs & can assure you that it is not an abinitio training aircraft!
You can test fly a Legacy at Redmond Oregon at the Lancair Factory or at Oshkosh in July. In my opinion, the Legacy flight controls are much better balanced compared to all the other Lancair models. The IO-550 Continental powered Legacy (310 HP) should cruise at 240 knots if well constructed.
