| Subject: | Elevator Rib Tip Assembly |
I'm trying to determine whether the Rib Tip Assembly is attached over or un
der the main elevator skins. Does anyone recall which skin is supposed to
be on top? I believe the main skin is on top, but the picture in the manual
appears to show the rib tip skin on top.

Tim brought up a good point - it's a lot safer to use.

Hi Steve,
I believe Figure 4 page 9-15 shows the main skin on the outside, which
worked fine for me.

| Subject: | Problem with Fuel flow transducer in the tunnel |
Fellow builders,
Some of you may be aware that I=99ve seen some deviations in fuel
pressure and flow in cruise flight in my RV-10: I=99ve got to
root cause.
After the past 10 months of investigation and discussions and general
head scratching I finally have come to a conclusion.
Executive summary: Don=99t mount the fuel flow sender in the
tunnel per the plans! It has too much pressure drop and gets too warm
in this location, this can lead to vapor lock. The onset seen as
deviations in fuel pressure and fuel flow.
The full report can be downloaded at:

Bob,
Are you running AVGAS or MOGAS?

Thanks for sharing your experience and the data. The charts and actual data are
great to see. I don't doubt typos have fixed your problem, but I wonder if this
is coincidental to the tunnel issue. Perhaps you can help me understand the
following questions?
1) if moving the red cube out of the tunnel (amoung other things) resulted in no
more problems, is your hyphothesis that the cube is heating up and causing vapor
lock?
2) all of the other people that have posted about red cube issues in the tunnel
have said the reporting of fuel consumption is high when the pump is on, but
no one else has indicate the say pressure drop and flow increase relating to a
cube in the tunnel.
3) is it possible insulating the lines and even the cube in the tunnel would do
just as good of a job? Is any where mounted to the engine or the firewall hotsidemreally
going to be cooler than the tunnel?
4) if the red cube heating in the tunnel caused the vapor lock, wouldnt that still
occur when it was on the engine and exposed to heat there?
5) it sounds like several things wee changed at once and undoubtedly fixed your
problem. How sure of you it was the red cube and not say a bend in a line, the
routing or one of the other variables that were changed.
I've gone back and forth on moving the red cube during my build. Most of the data
and issues so far with the tunnel have been reporting issues, not performance
related. If the cube IS causing vapor lock (or almost) and LOP is affected,
then that is a great reason to move it. I just wonder if we have enough info
yet to say that.
Just my initial thoughts and perhaps you are onto something here.
