Take Care:
Composite sandwich parts are extremely strong, but fragile at the same time. Always keep in mind that
these contest airplanes are designed for minimum weight and maximum strength in flight. Please take care
of it, especially during transport, to make sure that none of the critical parts and linkages are damaged.
Always handle your airplane with great care, especially on the ground and during transport, so you will
have many hours of pleasure with it. To protect the finished paint on the outside of the model from
scratches and dents during building, cover your work table with a piece of soft carpet, cloth or bubble-
plastic. The best way to stop small spots of glue getting stuck to the outside painted surfaces is to give the
whole model 2 good coats of clear car wax first, but of course you must be sure to remove this 100%
properly before adding any additional paint, markings or trim.
Adhesives and Solvents
Not all types of glues are suited to working with composite parts. Here is a selection of what we normally
use, and what we can truly recommend. Please don’t use inferior quality glues - you will end up with an
inferior quality plane, that is not so strong or safe. Jet models require good gluing techniques, due to the
higher flying speeds, and hence higher loads on many of the joints. We highly recommend that you use a
slow filled thixotropic epoxy for gluing highly stressed joints (eg: Hysol 9462). The self-mixing nozzles
make it easy to apply exactly the required amount, in exactly the right place, and it will not run or flow
onto places where you don’t want it! It takes about 1 - 2 hours to start to harden so it also gives plenty of
time for accurate assembly. Finally it gives a superb bond on all fibreglass and wood surfaces. Of course
there are many similar glues available, and you can use your favourite type.
1. CA glue ‘Thin’ and ‘Thick’ types. We recommend ZAP, as this is very high quality.
2. ZAP-O or Plasti-ZAP, odourless, or ZAP canopy glue 560 (for clear canopy)
3. 30 minute epoxy (stressed joints must be glued with at least 30 min & NOT 5 min epoxy).
4. Loctite Hysol 9462 or equivalent (optional, but highly recommended)
5. Epoxy laminating resin (12 - 24 hr cure) with hardener.
6. Milled glass fibre, for adding to slow epoxy for stronger joints.
7. Micro-balloons, for adding to slow epoxy for lightweight filling.
8. Thread-locking compound (Loctite 243, ZAP Z-42, or equivalent)
We take great care during production at the factory to ensure that all joints are properly glued, but of
course it is wise to check these yourself and re-glue any that might just have been missed. When sanding
areas on the inside of the composite sandwich parts to prepare the surface for gluing something onto it,
do NOT sand through the layer of lightweight glasscloth on the inside foam sandwich. It is only necessary
to rough up the surface, with 80/120 grit, and wipe off any dust with acetone or de-natured alcohol (or
similar) before gluing to make a perfect joint. Of course, you should always prepare both parts to be
joined before gluing for the highest quality joints. Don’t use Acetone for cleaning external, painted, sur-
faces as you will damage the paint. Tip: For cleaning small (uncured) glue spots or marks off the painted
surfaces you can use old-fashioned liquid cigarette-lighter fuel, like ‘Ronsonol’ or equivalent. This does not
damage the paint, as Acetone and many other solvents will, and this is what we use at the factory. At
Composite-ARF we try our best to offer you a high quality kit, with outstanding value-for-money, and as
complete as possible. However, if you feel that some additional or different hardware should be included,
please feel free to let us know. Email us: feedback@composite-arf.com. We know that even good things
can be made better !
