Here's a scratch-built LED flap indicator right
out of the Panos shop. It goes to show that
you can do just about anything with a little
ingenuity. Aircraft Spruce sells a 10-LED unit
manufacturered by Ray Allen that is also
used as a trim indicator.
If you build a Tornado, you'll definitely want
one of these. Affectionately called the 'Panos
Pumper', it came right out of our shop. It is
now manufactured by Chuck Riley in Fresno,
CA. Click here to see it in action.
Spring Suspension Nose Fork

Custom LED Flap Position Indicator

Here's another innovation right out of the
Panos shop. Use of the nose wheel pant on
the front of the Tornado requires the spring
steering option to be used, which makes the
nosewheel semi-free castering (direct spring
assisted). However, the majority of aircraft
(including certified) that use a semi-free or full
castering nosewheel may have a problem with
nosewheel shimmy. Left unchecked, it can be
very damaging to the airframe. Though some
Tornado owners have weighted the front of the
pant with several pounds of lead, we designed
a true dampening solution that completely
solves the problem. If you would like to build
one yourself, you may click below for the
photos, CAD drawings and video clip.
Custom Electric Trim Motor

Custom 3-Function Reversing Relay Pack
|
We needed reversible motor control for flaps,
trim, and electric in-flight prop to function from
both the front and rear cockpit. After a little
sketching on paper to refresh my memory, it
was off to Radio Shack for a six-pack of relays.
This unit allows control of all three motors from
both cockpits without any electrical conflict
between pilots if both happen to push any
buttons simultaneously. Aircraft Spruce now
carries a comparable 3-function relay pack
P/N11-02043. They also carry a single
function pack P/N 11-05312, in which you can
use two of these if you like their package and
only need to control two functions.
Custom Landing Light Flasher
|
This landing light controller flashes the landing
lights alternately. We built it from a schematic
posted in Kitplanes by Jim Wier. We also
added an override circuit that is switchable by
the pilot to provide normal operation when
desired.
Great news! Aircraft Spruce now carries the
AVIFLASH. A rugged, solid state and compact
unit (below) that has four cockpit selectable
flash patterns, and the other good news is the
price.
Where would your airplane be without an oil
separator? -- All covered in oil. The engine
oil system isn't complete without a means to
return crankcase oil spray and vapor back to
the oil pan. We designed and built all the
parts for this in just over an hour and had
them welded together. It has worked
perfectly in the three years since we installed
it. Here are the drawings to build one for the
Jabiru 3300, and the Jabiru 2200. We then
used a reducing tee to plumb it to a JAZ Mini
Breather Tank as seen below that we
purchased from Jegs and fabricated a simple
mounting bracket out of aluminum that bolts
to existing holes in the alternator frame.
3-Function Board
3" Heat Muff for Cabin Heat
|
Here's cabin heat that we also use for carb
heat with a 'Y' and a flapper valve inside the air
filter housing. Just take a 3-inch diameter
aluminum pipe and split it. Drill and fit holes for
the two header pipes. Re connect it on bottom
side with aluminum piano-type hinge, with a few
inter-locking tongues on the top side to prevent
the two halves from overlapping when the hose
clamps go on. Use fluting pliers to bend a pair
of zig-zag stand-offs and you're ready to run!
Make sure you have a way to bypass air when
it's not in use. We also use a 3" in-line bilge
blower so we have heat on the ground. It also
defrosts the windows in a flash. On a
25-degree day, it ran our 160-degree
thermometer beyond it's limits.
