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.
Consider it a great investment, the glue is the best you will use. One cartridge is plenty to assemble your
Velox.
C. WORKING WITH PNEUMATIC SYSTEMS:
The Velox XL uses pneumatic brakes and retracts. If you follow a few tips, you should have very
reliable, leak-free operation. Neatness counts.
All airlines should be secured to the airframe to keep them from flopping around or getting kinked. Use
tie wraps for this.
The other very important thing is to cut off the end of each airline dead square before installing it on the
nipple.
This is VITAL. You can either purchase a professional tubing cutter from your dealer (they are
approximately $10), or you can make up a little jig to hold the airline and keep a sharp, new razor blade
perfectly upright as you cut.
