| Subject: | Landing gear questions |
There was a several page pamphlet that came with my nose wheel.
Unfortunately, it's at the hangar or I would give you a quick response.
I'll try to remember to look for it the next time I head to the hangar. I
would just give Matco a quick call or drop them an email if you need a quick
answer.
Here's something I found on Tim's site
(http://www.myrv10.com/N104CD/upgrades/20090120/index.html):
Some tips from Matco on installation (Thanks Phil)
Per Phil's talk with Matco:
"I just got off the phone with Matco and thought I'd pass along some
information that is not included in their documentation."
1) The wheel halves should be torqued to 99 inches. This is more than a
standard AN-4 bolt (50-70 inches).
2) Hand tight is probably too tight. You should be able to get the seals to
hold position (when rotating the wheel in the correct direction) before
reaching the maximum you can tighten by hand tight.
3) Be sure to lubricate the seals and mating surfaces with grease, this will
help them hold position.
4) Once you put weight on the nose wheel, the friction of the bearing will
help hold the seals in place too.
5) Make sure there is no grease between the seal and the nut. This friction
will help hold the seal in place.

Has anyone gone with the Cleveland recommended Mobil SHC100 Aviation grease
for their wheel bearings? Any source for less than the 4lb can SkyGeek sells
for about 45 bucks?
Wheel bolt torque for the Matco NW511.25 nose wheel. Not one scrap of paper
came with mine besides the invoice. Can't find anything on their website.
I'm guessing some where around 90-100 in/lb, but would like to get it right.

I'm not 100% sure this is the link they sent me, but I think it is. It is under
section H.

I did call them several times to confirm the 99 inches because I couldn't find
it documented anywhere.

Kelly,
You can refer to the General Wheel and Brake data in our Technical section

The AN4 bolts use 80 in-lb.
Thank you,

BTW, I double checked with Matco in that the drawing had an erroneous 50
in-lb.
They confirmed the 80-in.lbs and have revised their drawing and other
references to the correct 80 figure.

I bought the same sender from the beginning.
I would also recommend the higher end EGT probes.

Ditto...as Scott says, ask them (GRT) for the Hastelloy EGT
probes if you ever change EGT probes.

| Subject: | Trim tab controls |
Hey Guys,
I've about finished up with Linn's idea of using a micro controller and RC servos
to operate a small tab extension on the aileron and rudder.
Here's a first, somewhat crude, youtube video of my demonstrator:
http://www.youtube.com/watch?v=rPFUCQeOM4Q
The servos are digital, high torque (88.88 oz-in) that weigh 1.59 oz. They are
not like the old analog servos -- they don't "hunt". They have carbonite gear
sets and there are metal control arms available. The idea is that they are light
weight enough to mount on a small access panel inside the rudder and aileron.
The digital readout can be customized to pretty much whatever the pilot
wants -- or to a bar LED like the one supplied for the elevator trim. I like
the digital cuz it gives a much more refined position, and cuz it was more of
a challenge, but I'm aware that most pilots probably would see that as a distraction.
The switches would be incorporated into the hat switch, toggle on the stick, or
on the panel. Brightness of the digital display is controlable. I was concerned
that the signal to the pulse motor servos might be compromised by the length
of the wire, so I put 25 ft. on each -- and they work fine.
I programmed in the feature to "save" the position you want, so that you don't
have to reset the trim every time you start up the plane (i.e., the basic program
sets the servo to neutral each time it powers up).
I got most of the materials off Ebay and RadioShack for the demo. Probably around
$100.
The brain of the system is the Parallax BS2 micro controller and I've built in
the MAX7219 8-digit display driver to control the digital displays. I started
from zero and taught myself enough Pbasic to program this thing to do what I
wanted it to do -- WHAT A BLAST!!
If I can talk Wes into it, I'll probably build these into an aileron and the rudder
that I have for the next -10 I'm building, then swap them out in his plane
to see if they work. If they don't or no one likes them, it's still been an
awesome project.
Later, - Lew
