Building TipsBasically
just folding plastic and a little cutting. Align pieces and glue
together with contact cement. The wooden power-cartridge and wing spar
epoxy together. The included video also helps get you started if you are
unfamiliar with working with the corrugated plastic.
Looks like you can
also build it as a tail-dragger, but I left mine with tricycle gear for
now.
The engine, fuel tank, nose gear, and radio all install into a wooden
platform called the Power Cartridge. It then slides into place and is
screwed into the fuselage rails.
I installed the receiver power switch at a 90°
angle to the side. Then a paperclip bent with a "L" on one end and a
loop/handle on the other. This switch actuator will exit the plane near
the wings, and easily slides to and from the switch's hole when the "PC"
is removed (look close at pics. to see it)
Landing Gear:
| I used nylon
bolts to hold the landing gear on instead of just using rubber
bands. One pair of bolts should be right next to
the inner landing gear wire (just behind it).

Mark and drill holes carefully, and not too close to the outsides.
On this one, hole centers were 1 1/4" apart (side-to-side), and 1
9/16" apart (front-to-back).

| The screws don't
hold well just screwed into the floor-board, so continue with
the modification. 4 holes are marked and
drilled into a small 3/16"x1 7/8"x2 1/2" plywood block that rides
inside. Epoxy 4 matching blind nuts into the holes (double check
your measurements). If all goes well, just drop it in
and use (4)
1/4-20x1" nylon bolts to mount the landing gear. This
whole procedure is only briefly mentioned in the manual.
Also notice the front landing gear "spring" is turned
so that if the front wheel gets pushed aft (back), the spring gets
tighter.
Anywhere wheel collars screw down, you should file
a tiny flat spot on the wire or axle, but especially for the upper
steering arm.

Protecting Paint: The white and grey plastic AirCore material itself is completely
fuel-proof, but the AirCore-40's paint job isn't. To preserve the finish,
use Flat Clear fuel-proof model paint (LustreKote) sprayed onto all
areas with painted-on red and blue markings.
