the battery is under slung from under the front
strut and on an angle, into the inside front end of the canopy.

- Before you begin, please also read the
completely. Make sure you are comfortable with
the assembly and tools required. This is not a hard assembly but
as with any hobby which requires user involvement, it requires
careful reading and patience. You do this and you too will end up
with an awesome Scale S300 for your mSR, mCX2 or Solo tiny
helicopter. If you need further assistance you can also

but you will need to use 150 mah battery with such to boost the
power requirement for scale flight. If you are in doubt of
diminished flight times with your "older" mCX helicopter please
purchase the older version kits for such, under our mCX Upgrades
page. These were designed strictly for the older mCX with smaller
diameter skids and boom. In contrast, the 2010 S300 kits have wider
diameter skids, boom and slightly different frame arrangement.

- Recommended option as this makes easier if you
have both Nine Eagles Solo and E-Flite mSR-mCX2 brand helis and you
can swap batteries back and forth, easily.
Because the Solo helicopters already have an angled boom, a la
S300 style, we
recommend the S300 alu boom and supporting fiberglass brackets not
be used, to save on weight. Use only the S300 LG assembly and
keep the tail stock.
- However, if you feel comfortable experimenting
a bit and modifying the boom support brackets slightly then,
follow same install procedure for the mSR. The mounting of the
fiberglass S300 boom support brackets to the canopy support arm
will not be the same on the solo as it is on the mSR-mCX you
can trim these upper ones and leave only the boom supporting
brackets, or leave the boom brackets out completely, since the
stock Solo angled boom will already support the S300 aluminum boom
only using the rubber boom support piece.
Reinstalling the boom assembly with the S300 aluminum boom
- Note that you will pass the entire stock carbon
boom, wires and connector as an entire assembly, beginning with
the connector, through the new
S300 aluminum boom, which has been sized accordingly to allow ease
of installation, as described. Do this carefully so not to scratch the enamel
on the wires. Once this is done the stock boom will stick out of
the aluminum boom a small distance at the front to safely keep the mSR tail rotor wires intact. Make sure you coil the connector
wires back, as in the stock setup, when you get to that point.

be snug, if the helicopter frame is fairly new and you have not
gone through several LG replacements. However if for some reason
it is not, you can tighten the fit by smearing a bit of CA glue
around the fiberglass strut support mounting pegs, to thicken
them up a bit. Do this in small and careful steps to avoid
excess CA glue build up. Test it, repeat if required.
Detailing the S300 Canopy
The canopy kit is supplied with printed vinyl
decals with color trim strips and logos. A couple tail molded
fins, same color as canopy, are also included for extra realism.
Make sure your hands are clean and dry when working with decals.
Carefully cut the trim color strips in segments.

edge of a hobby knife the backing material and peel off the
vinyl decal from it.
decals strips and logos using the photograph below as
reference. The vinyl decal material is repositionable, if you
make a mistake, you can redo it with ease. To apply trims around
curves, gently stretch the vinyl strips around the curve as you
apply to canopy with gentle finger pressure.
Installation of tail molded fins is simply
done using small pieces of Scotch clear tape to "clamp" the fins
around the boom tail end section.
optional. However, if you wish to light up your scale model, we recommend you purchase a set of lights from Tiny Brite Lights and install them according to their supplied
instructions. Use the following photo as reference for location
of lights, or install
- as you wish. A flashing white light
(not visible on this photo) is typically mounted at the boom
rear end. Red is for (Right) and Green is for (Left) with view
of helicopter coming towards you. Use only 3 lights, to
keep heli from additional weight.
