Larry, where is your baggage compartment, behind the seat or in the front
deck area? It would be better if the cg was a little forward but you have 2
things going for you in the configuration you have now. 1) you have that extra
24" of strech which should help in the pitch area. 2) in the landing phase you
will proberly have the belly board down which will tend to pitch the nose down.
Have you done any high speed taxi test with the board down? It would be
interesting to see if the tail wants to come up.

First the good news. I found out today that I will become
GRANDPA for the first time next May! Awsome!
Progress report:
I weighed the KR today. It is a 24 inch stretch with an
0-200, 600X6 main gear, 6 inch tailwheel, wing tanks
only, Cessna flap motor on the speed brake and basiclly
just a HEAVY bird. We used some very accurate electronic
scales. I'm using the same C.G. range as the standard KR
and will approach the rear C.G. with caution during testing.
Here is the long and short of it:
My C.G. range is __________________53.5 to 61.5 inches
Total empty weight including oil,
intercom and headset________ ____764 [email protected] inches
Pilot (me) at 204 lbs._____________968 [email protected] inches
Fuel (25 [email protected] p/g=155lbs._____ 1123 [email protected] inches
Pass @200 lbs._________________1323 [email protected] inches
I'll have to keep an eye on my baggage/passanger weight.
My C.G. will move forward 1 inch from full fuel to empty fuel.
As a frame of reference, Marty Robert's KR has an empty
weight of 780 pounds as of the last Gathering.
Jeff Scott has a KR basiclly identical to mine but he used
the Continental mount from RR ( I think) and his C.G. came
out an inch or two better than mine. I'm using a Hapi VW
mount with a 1 inch spacer. I believe the 2s moves the wing
back 2 inches or stated another way, moved the firewall
forward 2 inches. If my fuselage were built to 2s dimensions
I'd be right on the money.
I need to get my "N" number applied and get it inspected.
I've had it on the runway for some taxi test. I've had the
speed up to maybe 35 mph but have yet to lift the tail.
I'll keep you posted.
