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 (we use ZAP for many of the important joints in this aircraft).
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 surfaces 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 CARF 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.

Building Instructions

General Tips:
We recommend that you follow the order of construction shown in this manual.
The first thing to do is protect the finished paint on the outside of the model from scratches
and dents during building - so 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 of the fuselage 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% completely before adding any decals or markings. Additionally you can
cover the majority of the fuselage with the bubble-plastic used to pack your model for
shipping, fixed with paper masking tape, which also protects it very well.
When sanding any areas of the inside of the fuselage to prepare the surface for gluing
something onto it, do NOT sand right through the layer of glasscloth on the inside foam
sandwich !
It is only necessary to rough up the surface, with 60/80 grit or equivalent, and wipe off any
dust with alcohol (or similar) before gluing to make a perfect joint.
