,I’d like your bird’s operational specs inf I could I’m setting up our my POH for my Kr2ss and would like some starting figures Vne, stall ect, lift of speeds, a approach and touch down ect. ( or a copy of your POH)
Phil ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Phil, Glad to hear you're coming down the home stretch. A great deal of fun lies ahead. As to speeds and POH: The Vne is established in the plans as 200 mph. Other speeds for your bird will be determined with testing. On the first flight, if engine and control are good, go to altitude and do a straight ahead , power off stall or at least slow till you feel airframe buffet. Note "indicated airspeed". It may or may not be accurate but it will be your reference for other speeds. Don't assume your airspeeds will match mine as different instruments, systems,aircraft weights, wings, CG location, and all that. Use 1.3 times that IAS for final approach. If you have flaps or speed brake and intend to use them on first flight, deploy them slowly, at altitude, at intended approach speeds, doing gentle turns (15 degrees, 20 max) to insure no control issues in the pattern at the determined approach speed. Determine other speeds, downwind, base, etc. with testing and what feels comfortable for you with your bird. As for lift off speed, I have no idea. It depends on my weight on each flight. When the airplane feels light I apply a touch of back stick and it flies when it's ready. I hold the nose down for a few seconds and it quickly accelerates to from 90 to 100 mph on initial climb. If I'm going cross country I quickly transition to cruise climb in the 120 mph range getting from 700 to 1000 fpm. No point in climbing any faster if I'm going somewhere. I'm often asked what my touchdown speed is. Again, I have no idea. I go into the flare at 80 mph indicated (my bird is heavy and my wing is about 8 inches shorter than stock) and at that point I never see my ASI again. I'm guessing it is somewhere close to 60 mph on wheel landings. Your only concern on first flight is control ability and engine operation. If your ASI seems off, inop, or just bad reads, fly the airplane. It will fly with no ASI at all. If it appears too inaccurate, like mine did on a flight when a bent pitot / static went unnoticed on my extremely complete pre-flight, You may have to ignore it completely. In that case use a long runway as you will probably be inclined to land a bit hot. It will work if you don't panic. I'll attach a copy of my POH (Microsoft word) you can use as a starting point if you wish and add / delete depending on the systems / speeds of your KR. Be safe..... Larry Flesner
