Malcolm,
The hold up is on the sellers side - he wants the deal to be smooth and preferred
a 3rd party eyeball of float condition. All has been worked out now.

Hi Deke.
Last LEAF catalog I have (I think its the newest one) has new 582 with C drive
for $5701. With E drive, it's $6157.

Yes Sir that is what I would do. I think with the SS you can go higher
but I believe the limitation will shift to the heads and seats at that
point. Plenty power available at that for cruise. I think 1500 is OK for
brief full power climb outs. Seems the turbo 81 IMHO is sensitive to
rich/lean situations at least with present intake and fuel delivery
limitations. Now John A. may be working right past that now. It does not
like rich condition in either taxi or full power settings. I taxied at
900 to 1000F. Now full power was also tricky. At very lean 1550 1600
power up the yingyang. Go beyond that either in full power or trying
lean of peak and things can get real quiet. Not good quiet either. Don't
recommend it unless it's the granite cloud your trying to clear, but on
the other hand leave her to rich in cruise and the same loading problems
as before but bigger problem. I do believe in running LOP, but I could
never get a repeatable trusted setting. For those not familiar with this
procedure do some searches and read up, its worth the time. Yes you can
run cooler at a leaner cruise setting, not for full power, for cruise.
OK got to go, dinner calls.

Hi John and Rick,
It is my understanding from the experience of others
here that you are OK up to 788 C/1450 F EGT. Rick is
one of our GURU's for SS valves and other engine
improvements that keep them running, so I follow his
advice. I still have the origional valves, but I
think it is good to stay 1450 with the SS valves too.
Is that right Rick?
Oh, we take the EGT reading about 1" or 2.5 cm on the
pipe below the heads. Different results for different locations.
I try to run 1450 F/788 C in cruise and can usually
lean a bit to get that. Today my Fuel/Air gauge was
showing on peak at a little less EGT, but full rich.
Probably a lack of use problem giving some gauge
error, but I left it run full rich just in case.
Usually my F/A gauge shows rich at 1450, so I feel
safe to lean to it.
Your 760 EGT might carbon you up a bit, if you use
that for cruise. Seems a touch rich, but you will
know from experience.
I have to lean mine for taxi and runup or it shudders.
That is because I have a rich idle port setting,
since there is no choke for winter ops.
On my engine, I can take off at full power, full rich
and see well under 1400 F. When I reduce power the
EGT's rise as I reduce thru 4000 RPM, then falls
again. I haven't found a prop/power setting that will
keep me under 1450 in cruise in a range of 3600-4200
rpm. Maybe with more time I will. The engine isn't
broken in until 300 hrs.
I rebuilt my CAP prop and it works better than new,
but now its smoothest RPM is about 3200 instead of the
3900 I had before. Since 3200 engine rpm gives me a
good egt, I cruise there. I set 5.5 GPH on the flow
meter leaned to 1450 and use that for cruise speed.
Until I have some more anti-drag devices installed, it
feels like the plane is working too hard for little
more speed above those power settings. This is good
for 85-95 knots or 98 to 110 mph depending on
thermals. ;-)
Sounds like your water is right on, but the oil is
just a bit cool. That is the better fault to have.
:-) I think if you could keep the oil at 95, that
would be better.
Took me 6 years to build mine. Took you 10 years to
design, create and then build yours. The Wright
Brothers built theirs in less time, but I think we out
fly them by a bit.

I'm getting ready to look into sealing the gap between the
elevator and stab. on my model 7 and was wandering what affect it had on the
flying characteristics.
Does it make it more pitch sensitive or just give you more pitch authority?
I read in the archives that sealing the gap gives you more pitch authority
but does it also make it more pitch sensitive? And what about speed does it
help out any there too...Opinions and comments please.

Richer can give higher temps but not in the usual use as in full rich
for take off. Which in itself is a mis nomer. Full rich is what a
particular engine manufacturer says is and sets at full rich. Not trying
to word smith, but I doubt most carbs or TBIs for that matter are set
full rich. Full rich is the point of enrichment at a particular power
setting that results in acceptable or desirable EGTs. To answer directly
yes richer yields higher temps at the same manifold pressure because it
allows the engine to make more power. Only not true if you run rich of
peak which will in turn reduce temps, but IMHO cause undesirable effects
on the engine such as sooting, cylinder wash down, oil dilution, more
wear and such. Again full rich is a magic place for full power settings
that allows cooling while still not fouling the plugs and make optimum
power. Its kind of complicated. But I would suggest safer to run to rich
on full power than run to lean. Clear as mud.
Rick

Interfaced to the ECU I have a LED interface which gives an O2 value and the
lambda indication is spot on. All over to the little mad man in that black
box, I'll have to talk to his master....John

Richer can give higher temps but not in the usual use as in full rich
for take off. Which in itself is a mis nomer. Full rich is what a
particular engine manufacturer says is and sets at full rich. Not trying
to word smith, but I doubt most carbs or TBIs for that matter are set
full rich. Full rich is the point of enrichment at a particular power
setting that results in acceptable or desirable EGTs. To answer directly
yes richer yields higher temps at the same manifold pressure because it
allows the engine to make more power. Only not true if you run rich of
peak which will in turn reduce temps, but IMHO cause undesirable effects
on the engine such as sooting, cylinder wash down, oil dilution, more
wear and such. Again full rich is a magic place for full power settings
that allows cooling while still not fouling the plugs and make optimum
power. Its kind of complicated. But I would suggest safer to run to rich
on full power than run to lean. Clear as mud.

So Rick and Kurt, are you saying richer gives higher EGT or leaner? I
always
though being too lean gave higher temps? I recently did a linier
enrichment
on the EMC as the plugs looked a bit lean? John

Yes Sir that is what I would do. I think with the SS you can go higher
but I believe the limitation will shift to the heads and seats at that
point. Plenty power available at that for cruise. I think 1500 is OK for
brief full power climb outs. Seems the turbo 81 IMHO is sensitive to
rich/lean situations at least with present intake and fuel delivery
limitations. Now John A. may be working right past that now. It does not
like rich condition in either taxi or full power settings. I taxied at
900 to 1000F. Now full power was also tricky. At very lean 1550 1600
power up the yingyang. Go beyond that either in full power or trying
lean of peak and things can get real quiet. Not good quiet either. Don't
recommend it unless it's the granite cloud your trying to clear, but on
the other hand leave her to rich in cruise and the same loading problems
as before but bigger problem. I do believe in running LOP, but I could
never get a repeatable trusted setting. For those not familiar with this
procedure do some searches and read up, its worth the time. Yes you can
run cooler at a leaner cruise setting, not for full power, for cruise.
OK got to go, dinner calls.

Hi John and Rick,
It is my understanding from the experience of others
here that you are OK up to 788 C/1450 F EGT. Rick is
one of our GURU's for SS valves and other engine
improvements that keep them running, so I follow his
advice. I still have the origional valves, but I
think it is good to stay 1450 with the SS valves too.
Is that right Rick?
Oh, we take the EGT reading about 1" or 2.5 cm on the
pipe below the heads. Different results for different locations.
I try to run 1450 F/788 C in cruise and can usually
lean a bit to get that. Today my Fuel/Air gauge was
showing on peak at a little less EGT, but full rich.
Probably a lack of use problem giving some gauge
error, but I left it run full rich just in case.
Usually my F/A gauge shows rich at 1450, so I feel
safe to lean to it.
Your 760 EGT might carbon you up a bit, if you use
that for cruise. Seems a touch rich, but you will
know from experience.
I have to lean mine for taxi and runup or it shudders.
That is because I have a rich idle port setting,
since there is no choke for winter ops.
On my engine, I can take off at full power, full rich
and see well under 1400 F. When I reduce power the
EGT's rise as I reduce thru 4000 RPM, then falls
again. I haven't found a prop/power setting that will
keep me under 1450 in cruise in a range of 3600-4200
rpm. Maybe with more time I will. The engine isn't
broken in until 300 hrs.
I rebuilt my CAP prop and it works better than new,
but now its smoothest RPM is about 3200 instead of the
3900 I had before. Since 3200 engine rpm gives me a
good egt, I cruise there. I set 5.5 GPH on the flow
meter leaned to 1450 and use that for cruise speed.
Until I have some more anti-drag devices installed, it
feels like the plane is working too hard for little
more speed above those power settings. This is good
for 85-95 knots or 98 to 110 mph depending on
thermals. ;-)
Sounds like your water is right on, but the oil is
just a bit cool. That is the better fault to have.
:-) I think if you could keep the oil at 95, that
would be better.
Took me 6 years to build mine. Took you 10 years to
design, create and then build yours. The Wright
Brothers built theirs in less time, but I think we out
fly them by a bit.

I thought some of you might like to see a Young Eagles trip report. I had
to
get a Special VFR to take the young lad for his ride. Visit

Hello Roger,
Before I gap sealed my model 3, I couldn't do a 3-points landing, the plane would
stall and touch the ground with the main gear first, even when I was with the
stick in my stomach. Now, it's just perfect.
I don't notice any more sensibility in the pitch, only that little extra authority
when the stick is entirely pulled and the plane is near stall speed.
Cheers,
Michel
