Hey Scott,
In risk of beating this poor subject to death, let me say that to remove
the pilot wing with the enlarged channel method requires only a couple
of quick steps: 1) two screws to remove stormscope probe. 2) disconnect
probe from cable with a twist of the wrist. 3) Pull the 31 inches of
cable from the wing.
Reverse the process for reinstallation. With a service loop in the cable
at the outboard strake one does not need to d/c the cable from the cabin
side processor.
Thanks for the dialog. "There is victory is a multitude of counselors."
Paul

The "full length" antenna lead option was not discussed for the same
reason that "full length" strobe light power supply wires are not
discussed. Removing the wings with full length wires means
disconnecting the wires at the cabin side source, in this case the
remote mounted WX500 receiver/processor, possibly disconnecting the
individual wires from the wiring plug if the plug can't be pulled
through the wing, and fishing the wire through the wing - then doing the
whole procedure in reverse to re-mount the wings. Depending on where
things are mounted, and how the antenna wires are secured - this can be
a royal pain in the arss - hence the suggestion for a splice (which is
how most builders normally address the VOR, and communication antennas,
and also the wing tip lights).
Best regards,
Scott B.

Thanks for the feedback, Wayne. Enlarging the chase is so easy - as you
say 15 minutes work - that I can't imagine why anyone would want to go
to the time and expense of splicing the cable and why the other option
wasn't given in the VV article. I found that sharpening the tube without
filing in teeth was sufficient for a smooth cutting operation.

Hi Paul,
Regarding the storm scope antennas, I have installed all (7) of the
WX500 systems at the factory.
The connector at the wing/strake junction is accomplished with a metal
connector (Amp) and is a
bit pricey due to the cost of the connector and the labor involved. In
addition to preparing the SS
cable, you will need to add a braided metal shield over the strobe wires
in the same wing.
After discussions with BF Goodrich and several installations here are
the proven procedures for
the WX500. First of all the thing in the wing is NOT an antenna, it is
technically a DVDT probe that
senses energy spikes. The cable is shielded but is not an RF assembly,
the wires are for a simple
data link (about 12Khz). The shielding is to protect data integrity from
outside influences like the
strobe wires... Understanding this should assure you that the connector
will have little effect. We
are convinced that the best place to mount the receiver is under the
pilot side wing about 3 feet
out from the wing/strake junction. In the belly won't work! The cable
can be in the chase along
with the wing lighting and coax wires.
There are two ways to run the cable - one is to have the connector and
the other is to bore a hole
in the wing from the root to the base plate for the receiver (sensor,
antenna...). To bore the hole is
not too bad a job, I took a long piece of 1.5" aluminum tubing and cut
teeth on the end with a saw.
Then I alternately bent the teeth to the inside and outside about 1/16"
to enlarge the cut kerf in the
foam. The builder eyeballed my aim with the tube and I started twisting
the tube. We hit the mark
dead on and it only took about 15 minutes to do.
The biggest problem as far as we're concerned is the application of the
required ground plane.
It has to be at least 10 square feet! It can be a fine mesh or thin
metal and it is not necessary that
the receiver be centered on the gnd plane. One thing that must be
observed is that the receiver's
backing plate must be in intimate contact with the gnd plane. The ground
plane must NOT be in
between the foam and wing glass - don't even consider it! Laminate the
plane to the bottom of the
wing and fine bid over it after it has been securely glued down.
As with all aircraft (from Velocities to King Air's) you will probably
see a lot of strikes off the wing tips
even in clear weather. Not to worry, it ain't judgement day, just your
strobes faking out the storm scope.
The best and only way to fix this problem is to - you guessed it - shut
off the strobes. Goodrich has been
really good to deal with, their field service guys are most helpful and
willing to work with us.
Hope this helps -

The last issue of Velocity Views had an article from Scot Baker about
Stormscope antennae installation on the underside of the pilot side
wing. It was suggested that the antennae cable would have to be cut and
spliced if one wanted removable wings. Because there is two separate
layers of shielding in the cable, only a pro can do the job. The factory
will splice it for $300 if one sends in the cut cable after going to the
trouble to disconnect it from the control unit. Will a spliced cable
ever work as well?
I wondered if there weren't a better way. Here is another option. Simply
enlarge the wire channel 31" into the wing from the inboard end of the
wing so that the cable can be passed in and out of the wing to the
antennae . After getting a blessing from the factory, I employed the
following process:
1. Open the hole for the antennae into the channel as instructed in
the Views. (I was relieved that the channel was where it was supposed to
be 31" from the inboard edge and 4" toward the TE from the center spar.
To double check this location I noted that the drill point was right on
a straight line from the entrance of the channel on the inboard side to
the outlet of the channel at the strobe light on the other end.)
2. Fish out the strobe light, nav and com wires through the newly
cut hole so they won't be in the way. the later step of trying to cut
through the foam around the wires doesn't work. Don't ask how I know.
3.Enlarge the inboard fiberglass opening of the channel to 1.75 "
4. Sharpen the end of a 1.75 OD X 40" aluminum tube and pass it up
the foam surrounding the channel. It helped to re-sharpen the tube every
10" of foam cutting since the aluminum doesn't hold an edge.
5. Pass the com/strobe wires back out the channel.
6. One could leave the tube in place for ease of passage of the
cable. I am trying it without the tube first.
