| Subject: | reinforcing door hinges |
Timely question of reinforcing the door hinges, as that is what I'm
doing right now. I feel the standard attachment method is flawed, at
least for me. The reason is, I have always taxied airplanes with the
door ajar for extra ventilation, especially here in Las Vegas. When I
tried to open the door while taxing the Vans RV10 during a demonstration
ride many years ago, I was chastised for it because the demo pilot
warned me the doors are "weak link". A forward hinged door, like on a
Cessna, will take the prop-blast in stride, and the blast will try to
move the door in the direction it wants to go. A top hinged door when
hit with a prop-blast or gust of wind, will try to open the door, as the
in-flight RV10 door failures would indicate.(none of unlatched doors
tried to slam shut, that I've heard of). I have a secure strap
attachment nutplate, reinforced with an aluminum plate, glassed inside
the door halves, to allow me a nylon strap to hang onto while the door
is partially open, during taxi.The hinges are being reinforced with an
aluminum plate on the outside of the doors, thru which the countersunk
screws will pass. The plate is approximately the same size as the
indentations (pockets) in the inside of the door, where the hinges
mounts. The inside plate, also the same size as the tapered down portion
of the pocket, has nutplates mounted for the screws. The hinge is
embedded in epoxy/cabosil, that was set with mold release, so the hinge
can slide in and out of this channel, for removal. The inside plate is
then covered with carbon fiber, up the sides of the hinge pockets,and
epoxied on. The remaining depth of the pockets are then filled with
micro, so the pockets are now flush with the doors. The result is a
significantly stronger hinge attachment, that should survive my desire
to abuse my doors while taxing. Who knows, it may be strong enough to
survive an in-flight opening?

Wondering if any builders out there around Modesto within 2 hours need help with
a build or want distractions from a fellow builder. I have a work trip flying
out to Modesto on the 13th and leaving on the 15th so I have the afternoon/evening
on the 13th and all day on the 14th. If not does anyone know a good hotel
to stay at? I may go to Yosemite. I don't want to stay in MOD if I can
help it.

I suggest Yosemite. It's probably amazing this time of year with school
back in session, much less crowded but still terrific weather. Of course
the Ahwahnee is the most notable (AKA Pricy) place to stay in Yosemite but
also the Wawona Hotel is a very nice setting.
Bring your hiking boots, backpack, water jug, camera and enjoy.

It's supposed to be really nice here on the coast for the rest of the
week. It's the opposite direction from Yosemite, though.

| Subject: | 1st answered 2nd question about rudder trim |
Linn,
I had a similar idea but never could find any 12V servos. My plan was to
use an inexpensive servo driver designed to test the servos, but again never
pinned down a good 12V system, how is your search going?

trim
My plan is to attach a hinge to the TE of the rudder and one aileron,
driven by model airplane servo's. I don't like the big wedge cutout
..... this is for trim, not flying the airplane!!!
One advantage I have is that I can program a single-chip (almost)
computer to control the servo.

The model airplane servos are PWM (pulse width modulation) and need 5V,
GND and a 5V pulse. I'm not looking for 12V servos. They're all too
big and heavy, and they don't normally go to a set position. The 'zero'
of the model servos can be set by length of the pushrod or by programming.
Plan 1 is to use a programmable processor (Stamp Computer) to create the
pulse and drive the servo. Power for the processor can be a simple 7805
or a converter that plugs into a car.
I've already written the program to drive one servo, and it's easy to
port to two servos. One neat thing the program does is center the trim
on power-up.
Plan 2 is to use my MGL panel to drive the servo. MGL has said that
using similar programming thatg the PWM autopilot does can be used for
the PWM trim, and they have put it on the list of improvements.
I like the small size of the model servo and ease of installation.
They'll mount on the bottom rib of the rudder and outboard rib of the
aileron.
