A Confession
Once in a while,
I'm standing here, doing something.
And I think,
"What in the world am I doing here?"
It's a big surprise.

Kevin......Just my opinion. I have no experience with the capacitive senders.
I like the float type Van's supplies. When I first filled my tanks before
flying, we put in 2 1/2, 5, and 10 gallons in each side. The gauges said 2/12,
5, and 10 1/2. I did not find them hard to install or adjust. They are
inexpensive and easily removed if it were ever necessary. I have never heard
of them wearing out or failing.
I don't think you can use Van's inexpensive gauges with the capacitive type,
right?
One thing to be aware of: regardless of sender type, with this tank
configuration, anytime the ball is off center, the readings are inaccurate.
You should see how one tank goes up and the other down when you taxi around a
corner!

I haven't decided whether I want individual gauges or a engine monitoring system.
I'm leaning towards a engine monitoring system because I have one in my Mooney
(EDM-800 with all the options) and I like it.
I'm like the ACS 2002 and so I called the company this morning and ask them what
they thought. This was what they said concerning their system:
1. ACS supports Van's float or capacitance senders.
2. If you choose capacitance, you must purchase a converter for each sending unit
at $115 ea. OUCH!
3. For accuracy, floats will incorrectly indicate full tanks until you burn down
to 2/3 full at which the ACS will finally recognize the change and correctly
display the quantity level. It should be fairly accurate from there. Capacitance
should be pretty accurate at all levels except if there is water present in the
fuel in which it will incorrectly read "full" tanks no mater what fuel level.
I'm just starting to investigate other engine monitoring solutions to see what
they require. I may just end up installing both capacitance and later floats if
needed.

I believe that Van's fuel level gauge uses floats, howver they do sell a
capacitance sender that can be used with EI and the ACS 2002.
I hear that the capacitance sender uses two plates located inboard and outboard
and
a comparison is made between the them. Not sure if this is the case, but what I've
heard from others.
Anybody out there using a engine monitor other than the ACS 2002 or VM1000? What
kind of fuel sender is being used?

Paul,
I've used a gray roloc Scotch Brite disc in my die grinder and it works OK.
But most of the time I use 240 grit emery cloth like Curt mentioned or I rub
a maroon Scotch Brite pad along the edge. I prefer any of these methods to
using a wheel.

I have been following this thread with interest. There seems to be 2 schools
of thought on the subject and of course they are at right angles to each
other.
Some folks look at it as no big deal, just once over lightly with any thing
to take the burr off and forget it.
The side says, it needs to be as smooth as a baby's butt and do what ever you
need to do to make it that way.
Personnaly I decided to err on the conservative side. All small parts mostly
got done a bench or die grinder with a 3M wheel. I don't like using power
tools on large pieces or on sheet stock. It is too easy for the wheel to dig in
and spoil the the nice staight edge.
I'm a first time builder and new to the proccess and on limited budget. With
all that in mind I decided I would sleep better not having to think about it.

One of the engine monitoers available from Van's will read capacative or
float type gages.

here is my 2 cents worth....ac 43.13-1a page 126 #250 b. do not
use steel wool emery cloth steel wire brushed or severe abrasive
materials because particles will become imbedded in the soft material
and cause corrosion.....

| Subject: | Over the fence at 70 ........ |
--> RV9-List message posted by: "Rob W M Shipley" <rob@robsglass.com>
I'm still building and have no opportunity to land a 9 yet but for a plane with
a stall in the mid 40s and reportedly very stable handling 70 sounds rather high.
I used 60 - 65 in the Cherokees and 152s and would not expect to use higher
speeds in a slipperier (?) plane with a similar stall speed.
Is anyone using slower speeds?
