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.

CA glue 'Thin' and 'Thick' types. We recommend ZAP, as this is very high quality.

ZAP-O or Plasti-ZAP, odourless, or ZAP canopy glue 560 (for clear canopy)

30 minute epoxy (stressed joints must be glued with at least 30 min & NOT 5 min epoxy).

Loctite Hysol 9462 or equivalent (optional, but highly recommended)

Epoxy laminating resin (12 - 24 hr cure) with hardener.

Milled glass fibre, for adding to slow epoxy for stronger joints.

Micro-balloons, for adding to slow epoxy for lightweight filling.

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-Models 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.
