| Subject: | Re: Magnetized Dynon D100 Display |
Today I positioned a hand-held compass near my 10 year old D-180 screen.
The compass swung 130 degrees as it neared the left side of the screen, just
like cskelt's. Luckily my plane has a remote magnetometer, no panel mounted
compass. The master switch was off during the test. My instrument panel
does not have steel parts, just aluminum.

Any concerns about vibration fatigue of a 40 A automotive relay's single mounting
tab?
For instance B&C S8009-1.
Firewall mounted Lycoming tractor aircraft. Question from an RV 14 builder.
Thanks

| Subject: | $lower$ lacing material |
I told the list I'd look into some of lower
cost options for Dacron/polyester lacing
material.
I brought this spool in off Amazon for about 10.50
postage paid.

It's indeed the same stuff as the mil-spec
flat lace. Impervious to 400F exposure. Quite
adequate in strength for bundle ties. It's
thinner so easier to put 'pressure' on the
constrained materials . . . but it works real
well with the noose-knot but you don't need
to put a strangle hold on the wrap.
It will live happily under the cowl too.
I'm keeping this spool in my bin of tying
materials. It will be handy for sewing up
rips in flat materials too.

Interesting! Thank you for that. Perhaps John T
can enlighten us as to the cause.

I have an essentially new AeroVoltz 270 battery
I purchased new a couple months ago to evaluate
for a client.
https://tinyurl.com/yz6d4jpn
Found that it does indeed do what it claims; also
determined that it was not suited to his task.
Will put it up on eBay if nobody here on the
list isn't interested in it first.
Comes with factory instructions and the 'reset'
cable. Will include the plots of laboratory
data gleaned from this sample.
Would like to get $100 for it postage paid
to US addresses.

My a&p neighbor just rewired his RV6 using rib lacing tape made for
fabric covered a/c. Doesn't seem to be any cheaper than wire lacing
tape, but what about this?

It's polyester . . . should be fine. Good find.
