Griff, I think it might be of benefit to the entire KR community as I’ve seen very little discussion from years past about how to evaluate and improve longitudinal handling deficiencies after an airplane is built, even though it is very common in the production aircraft test and development process. Longitudinal stability and pitch sensitivity/pilot induced oscillation tendencies in the KR series have been discussed at length, but I haven’t seen any quantitative or standard task-based qualitative flight test analysis of the issue in the archives, even though many builders have taken a stab at modifications seek to improve stability. My goal is to add some additional data and results of testing to the body of knowledge and help builders and owners to have the knowledge to improve deficiences if they exist.
It would also be interesting to recruit a couple experienced pilots with different aircraft configurations, I’m thinking Mark Langford (multiple KRs), Chris Pryce (Corvair KR2S w/ mods), Zach Martine (O200 KR2S), John Shaffer (nose wheel KR2), and any other experienced pilots who wants to participate in gathering data to gain a better understanding of how well particular configurations affect the handling qualities. I think my particular aircraft might be on the more pitch sensitive end of the spectrum, but I believe it is by no means alone. My goal is to give folks some options to consider for making their airplane better behaved and more enjoyable depending on what phase of build they are in from beginning to improving an already flying airplane like mine. I’ve flown a lot of different aircraft types and my KR is the second most challenging I’ve been at the controls of to fly well, but I think it doesn’t have to be. I’m thinking I’ll either offer up a time, perhaps the evening of the 29th, to join a Zoom webinar or I can record it for upload to YouTube to share with those who are interested. I think I’d prefer to do it on Zoom so folks can ask questions, though. If anyone is interested in a Zoom presentation on Sept 29th at 8PM Eastern time I’ll gladly reserve the time, please replay to me via email or text at three-three-zero-313-9601.
