airplane, so take the time to do things right. Or REdo
them if they are wrong. Careful work will result in a long-
lasting plane that gives you years of pleasure, one loose
component could result in the complete loss of the aircraft
and all the components inside it, and someone can even
get hurt. So pause every once in a while when building it
and double-check your workmanship.
A. Introduction:
You have chosen a model that represents the pinnacle of
ARF technology. While there is not a lot of building to do,
there is enough to keep you busy for a few evenings.
Even if you have assembled maybe other ARF jets, we
highly recommend following our assembly sequence and
procedures anyway.
Chances are it will save you a lot of time, prevent you
from running down dead ends, and perhaps remind you
of a few small things that might end up saving your
aircraft.
We have tried to arrange a construction sequence that
will allow you to keep moving forward, rather than
standing around waiting for glue to dry before you can
proceed to the next step.
Just because the model is almost completely built does
not mean you can rush through the final assembly.
You need to employ fine craftsmanship every step of the
way, turbine models are critical. Keep this in mind with
everything you do, every part you install...look at the work
you just did, evaluate it critically, and ask yourself "is this
going to potentially crash my airplane?" If there is any
doubt about the work you have done, back up, and re-do
it properly.
B. Adhesives:
The correct adhesive to use for all procedures is Loctite
Hysol 9462. This is a very strong white epoxy that is
thixotropic. "Thixotropic" means it does not run at all, but
stays only where you put it. It is infinitely superior to
regular epoxy, even slow-setting epoxy, for our purposes,
because of this characteristic.
Regular epoxy will run downhill with gravity as it dries,
taking it away from where it is supposed to be.
A good example is in the hinges...using regular epoxy, a
good portion of the glue will migrate down away from the
hinge into the inside of the wing as it dries, and you won't
even know it is happening. Hysol stays where you put it.
The downside of Hysol is it takes overnight to dry
properly, but we have tried to arrange things to keep you
busy while waiting for glue to dry.
We also highly recommend that you only use a proper
Hysol dispensing gun, and only the long-type mixing
nozzles.
The short nozzles do not mix this glue enough, and only a
thin nozzle and gun will let you fill the hinge and control
horn holes properly with glue, you can't do it mixing your
Hysol on a flat surface and trying to get the glue in the
proper place by a brush or stick.
You can buy a complete Hysol setup with a gun, nozzles,
and two cartridges of glue from your dealer for
approximately $60.
