Though I have flown an L4 and Columbia with the idea of buying one at
  different times, I do not have even an hour in each type, so I have no way
  to judge or compare the different models, let alone discern the stability
  and control nuances - I just knew they were too twitchy for me. Only a
  qualified engineer could legitimately compare the numbers (derivatives) or
  an unbiased test pilot be able to discern the differences. My opinions are
  based upon feedback from qualified people, including professional engineers
  and test pilots who have flown the Lancairs - and that is as much as I'm
  going to say about that.

Rienk,

 

Thank you for your reply. Everyone has opinions on this forum about everything under the sun. Some are qualified by training and experience to offer their analysis of the facts-- many are not.

 

You have made some rather serious allegations about the Lancair IVP's safety record and its aerdynamic characteristics and flying qualities,  but at the end of the day you offer no factual evidence to support these opinions nor any personal qualifications to support your opinons other than to say "you have talked  to a few people."  I hope when you get the Envoy flying, you and your product do not get flamed based on unsupported claims such as these. As George Braly and company would say, "show me the data." You have not and cannot because there is no data to support your claims. If you are interested in the Lancair accident record, I suggest you visit www.ntsb.gov or attend the annual Lancair forum at Oshkosh where the past year's accident and lessons learned are reviewed.

 

After building and flying a Lancair IVP for over 3 years and 700 hours, I can say with some authority that there are no stability/ controllability issues that I am aware of. As a qualified Lancair instructor pilot and FAA designated pilot examiner I can say that the aircraft is safe in the hands of a competent pilot who makes good decisions.
