I keep asking for updates, but other than something from Jeff Scott after he 
tweaked his KR2S, I haven't gotten any more input for several years now, 
other than my own update of N891JF when I first bought it.  I have to admit 
that it's pretty disheartening.  Maybe some people will be stoked after 
reading the newsletters again, and submit some updates.

Having said that, the spreadsheet must be used "with a grain of salt". 
Interpretations of "cruise speed" apparently vary widely, and some of the 
stall speeds reported are clearly inaccurate indicated speeds, rather than 
GPS-verified speeds.  There are a lot of newly minted KRs out there, so 
you'd think folks would want to add them to the list, but apparently not.

KR> first sixty KR newsletters link enclosed

2014-06-23 Thread Mark Langford 
KRnetHeads,

The first 60 KR Newsletters have been scanned and posted.  I think you'll agree 
that the photos and text are far superior to what existed previously, and this 
one really is "searchable".  The newsletters are located at  
http://www.krnet.org/nl1.pdf .  I'd like to thank Wayne DeLisle for providing 
the newsletters that were scanned.  They are the cleanest genuine "original" 
newsletters I've seen and were originally published as four-sheet 11x17's.  I 
also have some later original ones provided by Jerry Price, which are in the 
works, and I have the remainder in original form.  For those who've never seen 
these newsletters, they are a wealth of useful ideas and information for 
construction of your KR, as well as a history of this homebuilt.  For those 
who've already seen them, maybe it's time to revisit them.  It's been a long 
time since I read them all, and glancing through here made me anxious to reread 
them all again.   At least you can see the pictures this time around!  This 
file is 33MB, so be patient.

More to come later...

KR> Real numbers for KR's

2014-06-23 Thread Rob Schmitt 
Tony,



Numbers are on pavement.  My landings on grass are shorter, more friction from 
the grass.  It also takes more runway to take off from the grass as well, same 
issue with friction.



Distance is from wheel touch down.   I fly out of a 4000 ft airport normally so 
I do not get challenged very often. I did go to a pancake breakfast about a 
month ago with a 2000 foot runway. Not a big deal, just needed to make sure I 
was not hot and high.



Thanks,



Rob

Rob,



Are those numbers on grass or pavement?  Is your landing distance from when the 
wheels touch the ground, from 50ft or some other height?



Cheers,



Tony

Landing is about 1500 realistically. I have landed on 2000 ft runways.  I bet 
if I had a belly board and better brakes I could get her down to 1000 ft. One 
benefit of trigear is you can land her and stand on the brakes to slow you down 
without ruining a propeller.


My stall is +-50 mph, but I certainly don't push my approach speed to less than 
70.

Yes, on a spec sheet one time.  But in fairness, we have to remember
Ken's KR only weighed 480 pounds.  Most of ours come in 50% or more
heavier than that.

I shot some awesome video yesterday in the KR.  Now if I can figure
how to get it on youtube.

KR> Real numbers for KR's

2014-06-23 Thread Rob Schmitt 
Larry,

I did not hot wire. I used a 8 ft + long sanding board.  The inner and outer 
ribs were the guide for the sanding board. The board was actually aluminum c 
channel with sand paper glued to it. I used a wood planner to get the styrofoam 
close and finished it up with the board. I do not have flaps or a belly board. 
I am having too much fun flying to go back and retrofit, but a belly board 
would be my choice if I did.

Thanks,

Rob
