Regarding the current thread on going faster with smooth paint/ polished
aluminum;
The CAFÉ group of Northern California specifically ran tests less than 3
years ago on an extensively instrumented test bed airframe to determine
the effects of a professional wax job and resulting performance.
I have been reading back through the archives trying to get some handle on
the KR performance. I found amazing quantities of brilliant information
(and plenty of the other), but I do not see any information to substantiate
the 200 mph claim - anywhere.
The typical KR2 /2S apears tp be stretch
Ron,
Given that configuration, my guess is 135 to 145. From the information that
I have seen over the years, the 2S drops 10 to 15 mph from the 2. Decide up
front if you want speed or comfort and be happy with what you get.
That weight and width are going to cost you. Get more horses if you n

Drag reductio
Ron.
I do not know all the answers for your question, but I do think 100 hp would
be much better suited for a KR of this size.
It sounds like a very nice sized KR.

Troy's wouldn't break 200 mph with the VW engine and the old wing. The
higher speeds came about after adding the new airfoil and the 0-200.

Any rough idea of how much was contributed by each one?

Indisputable evidence exists that reducing drag has a huge impact in speed.

Larry, The glider boys have found that if you matt your wing the drag is
appreciably less, hence before a contest you see all these fellows flatting
there wings with water paper.
No one has explained this to me satisfactorily, has anyone heard a
plausible explanation
Cheers
