It went out just fine but didn't for some reason show up in my digest-mode KR newsletter today. So here it is below. I think it's important to explain why I would 43 ********************** > "Touchdown should be at about 70 mph" For a KR that's just plain ridiculous. ***************** Sorry that was rather blunt. Most KR's stall around 50 MPH or a little under. Unless countering strong crosswinds, touchdown should be as close to the stall as possible. Excessive speed at touchdown is the primary reason for bounced landings and the various accidents which follow as the pilot tries to force an airplane back onto a runway after bouncing when, due to excessive speed, it wants to keep flying. That results in bent nosegears, groundloops, stalling out of one of the bounces and all sorts of other possible bad en ndings - all of which will ruin your day and damage the airplane. This isn't true just of KR's. Excessive speed on landing when doing first flights is a perennial major problem and is almost always the reason for the landing accidents that occur. Since I've never gone into a 1200 ft. strip with a KR I'd certainly be using brakes on roll-out as well - but that would be after touching down in as close to a full stall as possible. Truly full stall landings are difficult and perhaps impossible with KR's since the tail droops way down and hits first, even with tri-cycle gear KR's. The optimum KR landing procedure is best described in Jim Faughn's article on the subject found on KRNET. If one is very familiar with their conventional gear KR, doing a wheel landing at 70 MPH and using brakes against the aerodynamic forces you are keeping balanced with the stick can be done with time and practice but is more an exercise than it is a practical procedure. There's no real-world reason other than very strong crosswinds that anyone would ever land this way. Builders are not going to be doing their first flights with strong crosswinds. Suggesting to builders that 70 MPH is an appropriate touchdown speed is really irresponsible. Sorry.
