I never use the flaps at all, except for trim.

Nothing much more to say about the egt gauges except I don't know how you c
an run without them. Probe placement is important and there's been some tal
k about that on this list. My exhaust manifold came with holes already plac
ed so it was a simple matter of assembly. After installation, it's a balanc
ing act between prop pitch and carb settings to get the rpm's and egts wher
e you want them. Conventional wisdom says egt's should not go above 1050-11
50 degrees. Mid-range rpm's-were most problematic for me. After that, ins
pect your plugs to assure the burn is proper and gauges aren't lying.

Lucky for you I already have some pix I had sent to another poster off-list
'cause it's pissin it down out there at the moment ;-)

I haven't seen the one on the Euro-Fox but I do know the UK Fox has a lot o
f mods to the original kit. I seem to remember the normal (US) flaperons ar
e meant to be limited to around 23 degrees but I might be wrong.

The picture of the "console" shows the continuous horiz tab setting nearest
and the flap handle (with the release button on top) is on the far side, s
et for zero flaps in the picture. I never use full flaps until I am lined u
p on final, at that setting it is easy to run out of roll correction if a t
urn is too steep on base to final. Had it happen a few times early on!

Any comments on the EGT gauge and sensor you have talked me into?

I have no "notches" on my flapperon lever. It's a continuous range from 0 t
o a stop at about 15 degrees which, I think, is where the "flaps" begin to
interfere with operation of the ailerons.
-
I'd like to see your tab set-up. Is it like the one on the Euro-Fox?

I have dug out some build documentation - two MANDATORY modifications issue
d by the PFA. The first describes adding the horizontal trim tab for those
who have already built the stabilisers and those that hadn't, mine has-co
mpletely reworked tubing on the starboard side to allow for an inbuilt tab.

The second states: "Original equipment on Kitfox does not provide for a pos
itive location 'gate' on the flap control lever. It was original intended t
hat the plane be trimmed by use of the flaps. However flight tests indicate
a more suitable situation would be to use a trim tab (adjustable) on the e
levator and use the flaps as flaps only. This is the recommended practice.
In this situation 15 degrees of flap is the maximum required in any situati
on. Hence a suitable gate is required that can be clamped to the diagonal t
ube framing floor to seat that will restrain total flap lever travel to 0 -
15 degrees in say 5 degree steps"
-
Mine has 3 notches: 0, 15, and something between. The first "notch" adds ab
out 90% lift and 10% drag (% of the total effect), used for short take-offs
and nose-down on approach. The 2nd notch (15) adds 10% lift and 90% drag.
- I'd have to guess that your adding "10 degrees or less" is adding a *lo
t* of drag at cruise speeds. I never use flap until I am down to about 55 m
ph approach speed, or remove it until well off the ground on take off; in f
act it is placarded never to use flaps at all above maneuvering speed, 70 m
ph.

EGT gauges - I looked on AircraftSpruce.com and there is a wide range of ty
pes and prices. Can you (or anyone on the list)-give recommendations for
my gray head 582 please. Also - what sensors and where do they mount?
-
Spark plugs - I will pull them all next time I am "under the bonnet", which
should be later today, and get back to you on the condition.

I use the flapperons (about 10 degrees or less) for nose down trim at cruis
e speeds (60-70 mph). As power is reduced, flapperons return to neutral. Wi
th no flaps and cruise power, airplane will climb. My CG is dead-center of
the range.

You must get egt gauges Bob. With a 2 stroke, it is probably the most impor
tant engine instrument on your panel. It will tell you immediately if mixtu
re is too lean (High egt) and prevent melting holes in your pistons. Checki
ng the color of your plugs frequently will also tell you alot about fuel bu
rn (lean-rich). You're shooting for a light brown color. No black soot (too
rich) or gray ash (too lean). Mike Stratmann wrote a good article ("Part 9
") on reading plugs. Check it out at: -http://www.800-airwolf.com/article
