of steps accumulated here, just adding to the fuselage build, but
nothing that deserves it's own section... First, there are a pair
of grilles below the exhaust to be mounted, and I used a laser level to
get both sides lines up and perfectly straight.
I laid down each grille,
tracing the vent openings with a mechanical pencil in order to determine
exactly the size of the opening I wanted to cut. Then I used Aeropoxy
and tiny screws to affix them to the fuselage.
The screws were really a
lifesaver, as the nose piece needed to be compressed horizontally for
proper fit. I was able to drill the holes while holding it compresses,
then apply Aeropoxy before screwing it into the holes, which gave me the
proper compression. Worked like a charm!
For my electrical testing,
I built a test module using a 5000mA 2-cell LiPo, an Align BEC to
regulate it (which has a built in switch and 5-LED battery monitor, a
servo exerciser/tester, a 6-channel receiver, and a Dimension
Engineering LED controller with auto current sensing. This lets me
test and exercise any part of the mechanics in or out of the
fuselage. Darn handy gizmo.
In preparation of the gun
pod mechanism (and the Sunburst/Chaff dispensers), I will need some
pretty precise throws on the servos. I built this test jug, and
made a LONG servo arm with a slot and a ball-link-locknut combo that
will let me determine the optimum placement of a ball link on a servo
are quickly and accurately.
The back ends (where the hinges will go)
of the Sunburst/Chaff pods was rather flimsy and had a bit of a curve to
them. I reinforced them with some very thin plywood painted with
thin 24 hour West System Epoxy. By clamping them to a marble tile,
I got a nice flat surface.
I thought about hinges for
the Sunburst/Chaff pods. Looking at the blueprints, I see they are
referred to as "Rear Defense Pods" so I guess I will be
referring to them that way from now on... Anyway, I
wanted a hinge that would NOT sag. I ended up using a brass tube /
brass rod combination that supports the pod from top to bottom:
Finally, on the
ScaleRCHelis.com forum, one member had complained that his dogbone
receptacle had melted under operation! Melted? I have been
using the metal ones from the Kyosho Inferno GT (RC Car). An
additional benefit, is that they can facilitate easy removal and
reinstallation of the mechanics in a scale RC Heli!
