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_ 
(http://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. 
 
Regards,
 
Jeff Edwards
Lancair IVP
