ASSEMBLY MANUAL: Glasair SII / III
II RG! For the complete lineage of the Glasair series see their website at www.
glasairaviation.com. No matter what you call it you have your hands on a slick model
of a very impressive full size aircraft!
Please note that we use aircraft terminology in our
instructions. Specifically ‘Port’ is to Pilot’s left,
‘Starboard’ (or Strbd) is to Pilot’s right, ‘Forward’ is to
the front and “Aft” is to the rear. No matter how you may
have the model turned “Port” is always the left side of
the aircraft as the pilot sits in the cockpit facing forward.
A note about the covering -
Your Glasair is covered in ‘Oracover’ – commonly known
as ‘Ultracote’ in the U.S. This is a high quality material, but through temperature
changes during shipping, the model may show wrinkles. This is normal. This
symptom is also more visible in that the model is fully balsa sheeted. The material can
easily be tightened by the application of heat from a hair dryer/heat gun or hot iron. If
using an iron, a piece of lightweight cotton (e.g. sheeting) placed between the iron and
the covering helps to even the heating. Pressing lightly will transfer the heat to the
covering, shrinking the material. Piercing a bubble with a pin and rubbing the hot area
with a cloth further helps remove the wrinkles.
Oracover is a very slippery finish that that resists adhesive bonding. It
must
be
removed from any joint to be glued. Failure to remove the covering from glue zones
will result in failure of the affected glue joint and likely damage or destroy your model.
The recommended engines are a 1.08-1.20 two stroke or 1.20-1.40 four stroke.
Experimental Aircraft Models discourages the use engines larger than this range. The
Glasair is an aerodynamically clean design that simply does not require larger than the
recommended engines. Some other notes on engines: most of
the engines in the recommended size range weigh roughly the
same - 28-34 ounces. Using a lighter engine will likely require
making up the difference with lead weight. Using a
larger/heavier engine might mean that lead will have to go in
the tail!
For 2-stroke engines the standard muffler will be very difficult –
or impractical to use because it will project way out of the cowl
and might also require modifying the firewall for clearance. For
this reason 2-strokes should be fitted with a side mount or “Pitts Style” muffler to keep
the installation simple and preserve clean line of the cowl. The mufflers on 4-strokes
are generally easier to package.
The Glasair is supplied with an assortment of hardware, but a lot of modelers have
their own preferences. A couple thoughts to keep in mind:
Keep close track of all the little screws and hardware sets located within all the
large component bags. It can be easy to misplace these items – not that WE have
