Pre-fitting the battery and servos.
The battery is about as far forward
as it can go without intererring with
the nose weights. Used a bigger
battery which alleviates the need
for as much nose weight later. |
Had some coroplast scraps around,
that I put over the batteries. Had to
be careful when routing at the
battery holes not to go all the way through. |
FMA Extreme 5 receiver test fit.
It looks snug, but the antenna is mashed
in there too for the moment. I installed a
remote switch off to the right. |
The battery, receiver, switch
and servos are all in place and
the antenna wire is disappearing
off to the left, goes through a hole
under the balsa filler and makes a
turn around the back of the wing.
Masked so I can spray with 3M F77.
This is the time to center and install
servo arms after spraying and
then lay them down flat and install
servos. |
Covered the center section with full
runs of double direction fiber tape from back
to front over LE and diagonally across the
bottom. Some overlap with outer wing
sections. Work outside in, and overlap a
fair bit. When done, remark the rectangle
around the ballast cover so you can see it
through the covering.. |
The tape coming over the LE
turned about 45 degrees so I
carried it all the way to the
back with overlap. The bottom of this
sucker is strong. The overlap
from the top is important because
as you move toward the center it'll
end up with less overlap on the
bottom because the angle changes
as the LE gets thicker.. |
Top covered with strapping tape. Also
used 0.66" wide strips to cross brace
the outter wing panels for
added strength and reduced twist.
(2" tape split into 3 is 0.66). |
Bottom side with X bracing.
Resprayed outter panels with
3M F77 and a light coating over
the center section as well.
Covered with covering tape
and Ultracote. |
The tail boom installed with
wires in place. |
Upper tail mounted on the wires.
It just sits there and is taped in place. |
Showing how it pulls out.
It was so tight I actually put a dab
of lithium grease on the rod and now
it's still tight, but goes in and out smoothly. |
The switch installed a little way from
the receiver. This would be a good
application for Hollyday charging plug switch.
My charging cable is buried in front of
the receiver and I just sort of pluck it out
of a small slit (hinged covering in front). |
