Jeff,
You're on the right track. IF the plans call out for a net 1 degree
difference (my plans are packed away, so I can't confirm that figure), try
and maintain that. Set the wing first, then adjust the horizontal to net
the 1 degree difference.
I ran into a similar situation with my airplane but didn't adjust the
horizontal stab. My airplane has light engine/prop combo, so I rationalized
that I might not need the full 1 degree difference in incidence. If I
recall correctly, I've got about a quarter of a degree less than called for
in the plans. The plane flies just fine...

--> RV-List message posted by: "Darwin N. Barrie" <ktlkrn@cox.net>
Hi Everyone,
I have the following for sale. Lycoming TIO540 A2A
serial number L3848-61
310HP (with the turbo)
The engine was last used in a University wind tunnel and was set at 19" of manifold
pressure. The original log books were lost so it is strictly Experimental
at this point. The engine was used for 880 hours by the University and that was
from the last overhaul.
Several A & P's have looked at the engine and said it looks great. If I don't get
any reasonable offers here I'll put it on Ebay, but I thought I'd offer it
to the group.
I was going to put it on an Aerocomp but bought an RV7 instead. Without the turbo
charger this might be a perfect engine at a great price for an RV10.
$15,000 plus shipping. I have pictures for those who are serious.

Subject: RV-List: AoA indicator - try a different angle!!
How about getting one of those Ray Allen (MAC) position sensors ($34) hooked
to a small vane positioned in the relative airflow. Maybe in the fuselage
side, vertical stabilizer, wing-tip, or where-ever -- the hardware and
wires required are very light.
Then use one of the Ray Allen LED indicators ($70) a non-Proprietary,
Professional-looking, Bacon-saving, Lift Reserve device for just over $100
with money left in the bank!
<><>Good idea, Give it a whirl ~~ I think you will learn a lot as many of us
have that produce the AOA and AOA type systems. Remember ANY change in flaps
changes the AOA the wing stalls at! There are lots of "Gotcha Ya's" there, I
know. I started trying to get an inexpensive fully usable AOA system 37 years
ago! Please don't mount in the prop blast on fuselage or rudder, it will
kill you if you follow it, will be reading airflow influenced by prop, not what
the wing is seeing. Talk to an aerodynamicist and get a full understanding on
AOA. I'm sure that most of us that produce the systems have had several
consultants to insure we were on the right track. We just have different methods
of
doing similar things. I used the vane as I knew it would measure the
relative wind, others use electronic computations because they were EE's and so
on.
If it were that easy there would be dozens producing usable AOA systems. The
precision instrumentation sensor (dual stainless steel ball bearings, full
military spec) the vane mounts on that we use cost over $50.00! You could go
cheap, but why have unhappy customers when the sensor failed? We spent about 3
years trying to find the sensor we now use.
Competition is always welcome, We all are trying to make flying safer!
Comments off line please as I don't have time to get on web daily.

I have 2 (two) of these Garmin Rino 120 GPSs for sale. We used them last year at
Oshkosh and work great. 2 way radio and GPS combined.
When you transmit it updates your position on the other unit. Easy to find the
wife in the flea market while you're checking out the
new avionics.
Regular $250 each. Both for $450. Free shipping anywhere. Includes all manuals
and PC connection for software updates.

| Subject: | howling brake noise |
--> RV-List message posted by: "Randy Garrett" <rgarrett@objectsciences.com>
The rubber o-ring that goes around the cylinder for my brakes started
leaking a few weeks ago. After I replaced the o-rings (both were going
bad), the brakes started making a noise that sounds a lot like an air horn.
I thought it might be some brake fluid left on the pads. Since the pads
were getting rather worn, I replaced them and made sure to clean off the
disk fairly thoroughly. Still get the same noise. I did do the brake
break-in. They stop fine. They don't stick. The noise only occurs when I
lightly to moderately apply the brakes.
Suggestions?

| Subject: | leaking lycoming intake tube |
--> RV-List message posted by: "Randy Garrett" <rgarrett@objectsciences.com>
While changing the oil, I noticed blue fuel stains on the intake tube for
cylinder #4 on my O-360-A1A. Checked with my local A&P, and he said the
gasket where the tube goes into the cylinder is probably leaking. That
certainly appears to be the case.
A few questions:
Where's a good source for the gasket (an actual part number would be good
too)
Any special tricks or traps I should beware of? Looks like it should be
straightforward to unbolt the tube and unscrew the worm gear clamps holding
the rubber sleeve over the bottom of the tube.
Thanks,
Randy
