>>This does bring me to some questions about Angle of Attacks.  I do not have one in my Lancair 320 MKII but would like to add one.   I have heard that they are MUCH easier to add while building but I am flying now and wonder what you guys think is the easiest AOA to install on a flying aircraft.  My wingtips are not removable.<<

 

 

We've installed a couple AFS AOAs after the plane was flying.  It's a bit more involved than an installation during construction, but still not that difficult.  And the benefit is definately worth the effort.  The sense tubes are small eneough, 1/8" OD, that they can be run down the back of the aft spar, in front of the flaps and ailerons.  Just be careful about control interferance.
