As might be expected, my usual suggestion is that someone do wind tunnel models of the various Lancairs and take data on pitching moments, for stall recovery. NASA Langley might be interested,as they were with canards like Piper's, and did studies also of the Dragonfly tanden wings ... and they discovered marginal restoring pitching moments at stall AOAs. They also have a spin-tunnel. I mention these two things because they are a serious concern of the FAA in TC-ing standard category aircraft, and I have not seen any reports, data or testing information other then incipient stalls, and reluctance to evaluate recovery from developed stalls or spins, and I noted several test pilot reports that criticized the light pitlot pitching force per G. In other words, lets evaluate the designs rather than carp on more and more training .... this group is fraught with very qualified pilots, and they are having accidetns. The cause, imho, is likely elsewhere. Respectfully offered, Terrence L235/320 N211AL
