--> Kitfox-List message posted by: jim cantrell <jcant1@direcway.com>
Hello List
I have just attached the wings for adjusting the forward wing sweep with a one
degree sweep. Const. manual says measure outboard 120" from the front spar attach
lug's outer edge out to front spar leading edge on each wing. I am confused
as where to place the front spar on the attach lug for measuring this distance,
I have the front spar up on the attach lug as far as it will go. Do I mark
the lug's outer edge on to the spar and measure from there? Installing Rotec
radial R2800. Can someone help me out here?

Jim,
matter much where you measure from for your 120 inches. I would measure from
the attach lug on the spar carry through. IMHO

Jim,
I used the a projected reference datum of the wing spars outside radius forward,
and then added the distance needed to obtain a reference beyond that to mark
a point that, with a taught snap string taped at the 120" points on the wing would
give me a one degree forward sweep. Secure a 4" reference post sticking out
forward, onto your leading edge spar support tube.

--> Kitfox-List message posted by: "Andrew Matthaey" <spaghettiohead@hotmail.com>
I re-pitched my prop for better cruise a little while back...hadn't done
much flying until this past week at a fly-in, and now I'm a bit concerned
about temperatures...
My Coolant Temp mid-day when it was hot and humid was hovering just a hair
under 180 on climb-out and dropped to 170 in cruise. My EGT is now at about
900-925 in each cylinder at cruise...the previous owner says that these
numbers are fine. Any other opinions (or facts!)
Thanks a million!

Sounds like your coolant temps are about right (for the conditions). I get
nervous when they go above 180 and have had that problem since the beginning
on climbout (hot days). My cruise always hangs in there about 165. I think
(opinion) that 900 degrees EGT's are a bit on the cool side. Even the Rotax
manual recommends somewhere around 1100 or so.....I don't have the manual in
front of me...
You asked for facts or opinions. The book (facts) says "around" 1050 to
1100. Many like to run close to 1200 (opinion's). I split the difference
and run between 1100 and 1150. Again, I don't have the book in front of me
so an just using numbers from memory.
You have a situation that might prove interesting...If you increased the
EGT's to the book number (1100 or so), would this cause your coolant temps
to increase???? If it did, you might find yourself like many others, having
too high a coolant temp???

Sounds similar to mine Andrew! Ambient temperature of 27deg C this evening,
and water temp right up to 80deg C on climb out, but soon settle in cruise.
I would be concerned if it went higher and would consider dropping the rad
an inch or so into the airflow more.
However, we don't normally get 30deg in England ;-)

Hi Andrew,
Well, your coolant temps are in line...be glad they are not higher. We
commonly see temps in the mid to high 180's ...(sometimes hotter) on hot
days.
The reason your EGTS dropped off is you are operating at a wider throttle
setting than before. What is critical is what EGTS are you getting at wide
open throttle (WOT).... The midrange EGT ( 5200-5600 rpm) can be easily set
by adjusting the jet needle. 900 is a bit low and will result in a build up
of carbon in the piston rings. You should aim for 1050-1100 at cruise rpm
and 900-1000 at WOT.
Quite often the gauges and probes are not that accurate and should only be
used as a "relative" (i.e. relative to the last few flights and similar
conditions) reading.
You might find your coolant temps a bit higher than before (under the same
conditions) because you are working the engine just a bit harder to atain
the same rpm (coarser pitch on the prop.).
You did'nt mention what rpm's you were getting at full throttle and what rpm
you were cruising at.
Hope this helps

Well I'm glad my coolant temps are ok, but the EGT's make me nervous with
the carboning up issue! The CPS catalog says 930-1200 is normal...I guess I
could just re-jet her and lean her out (hasn't been done since last fall, I
believe). That oughta help without having to repitch my prop again...
Thanks group,
Andrew
