Mickey,
I used a Grand Rapids Technologies Part Number LPS-02 low pressure
sensor suitable for fuel and coolant pressures between 0-28 psi.
My coolant pressure is always above 5 psi so the low war ...

Bob,
I use a pressure sensor in a threaded boss in a metal hose connection.
The warning is provided by
my Grand Rapids Technologies E I S. It's alarm is set at a minimum 4
psi. You loose water ...

Roger,
The numbers you provide seem to be fairly accurate for the engine and
prop as applied to the 601.
I fly a Subaru that has a Warp Drive 70-inch ground adjustable prop.
With the prop set a ...

Dave,
Try the 2-inch aluminum square tube in the hardware section of Lowe's or
Farm and Fleet stores.
This stuff is dimensionally good and not terribly expensive.

Jennifer,
Pleased to have you among the builders here. There's lots of knowledge
within the archives and responses here are unusually civil for this medium.
I'd mention that it is also really use ...

Brandon,
I used J-nut clip on styles 1 & 2, principally the style 2, which is a
little longer on firewall and
instrument panel flange. Style 1 on the sides. Part numbers supporting
6-32 an ...

Bob,
The forward top skin can be removed with J-nuts if you configure the
sheet metal somewhat like what I've done at the front sides. These
J-nuts are for
6-32 screws and cost about $10.00 for 5 ...

Lynn,
You and Nick have a disconnect in communication somewhere. The drawings
are accompanied by a rather good construction manual, a CD and lots
of pictorial content. You should revisit what yo ...

John,
If you're speaking of the magnetic pickup at the flywheel, these can
become intermittently-functional.
On my first flight, the secondary ignition magnetic pickup quit and as I
taxied back ...

Tommy,
You're right, you need to fix it or it will "list" a bit and never look
right as well. You might even have a one-sided torque on touchdown.
It would appear that you need to saw o ...

Ralph,
There are two or more types of cowl that fit Subaru depending on the
engine supplier/redrive
etc. NSI has one as does Zenith for the Stratus, but they're a bit
different in the way they'r ...

*Scott,
I purchased my latches from Zenith, but they can be possibly purchased
from the company below.
Also, if you're going to use the same latches, welded to the frame, you
want to be cautious ...

Tim,
My Lithium battery was pre-installed in the remote panel-mount and I was
to replace it
just to be sure. The life expectancy for this cell was stated at 8
years, so I marked it 2005
and re ...

Steven,
The trim tab seems a bit much initially, but when you fly a plane that
has a shorter span
and loading becomes one sided or your trim isn't exactly where it should
be to begin with, the t ...

Jari,
If it were neccessary to cut a structural tube to obtain a bend, the
strength could only be recovered by
welding a splice, gusset, strap or sleeve section across the cut. It'd
be better t ...

Gord,
DOT 5 is what is recommended for Matco brakes. Bleeder screws are
better placed downward
to avoid putting the drained fluids on the brakes at disassembly. Also
you need to maintain the s ...

Gord,
The brakes are easiest to install in the orientation shown on this
link. Brake assembly shown inside, low and angled to the rear.
This puts your hose connection up and the bleeder down. Al ...

Thilo,
I did my safety stop/tow bar ring from an example provided by Bill
Morelli. The T-bar handle is thin 4130, 5/8-inch o.d. with an aluminum tube
riveted between it and a tube welded to a tape ...

Tim,
If you're using the 8-inch wheels the tire size is generally called an
4.00 by 8.00.
I use a Michelin 3.5 by 8.0 called the S-83 tire. It's used on motor
scooters. Excellent
tire, rounded ...

Jeff,
If you want to keep the bolt heads outside, (my preference) you might
consider making
an 3/16 inch thick bar with threaded holes and place thin radial lock
washers outside.
Fussy work to ...
