Tim,

 

There is nothing wrong with the airfoil.  Like all airplanes they need to be balanced correctly and flown with sufficient speed.  What you are talking about is completely changing the design characteristics which would be far more dangerous than you could imagine.  Keep the RV wing on the RV and the Lancair wing on the Lancair.  Balance it correctly and keep the speed up.  For my airplane the never go below speed is 85 kts unless I am practicing stalls with sufficient altitude.  When you are ready to fly it have it checked over by an expert in LNC2’s and do not attempt the first flight on your own.  You will also need training by an experienced Lancair 320/360 pilot.  When you are ready to go post it here and I am sure there will be plenty of us that will help you in the right direction.

Hi all.

 

My LNC2 is near completion and I have started preparing all the paperwork necessary for the flight permit.

During my research I have stumbeled across the NTSB website and made a search on "Lancair 360". For those of you who have not done that (probably most!), this is HORRIFIC reading !!!

There seems to be quite a large number of stall related accidents, which leads me to believe that the airfoil is basically unsafe. Anyway, I am not going to fly this thing as is, although I have had my license for more than 20 years and have accumulated more than 200 hrs.

I have now come across a set of RV-7 wings that survived a hangar collapse last winter. This airfoil seems much more forgiving, anyway, that is what my A&P says, and I am trying to come up with a way to install them on my otherwise finished airframe. I will, of course, have to keep the stub wings and make them fit the slightly larger RV wing but, apart from that, would I be in for at lot work? Has anyone done this before? Any advice taken!

 

Regards

Tim Jorgensen

Lancair 360, was 95% done, now back to maybe 60%.....
