1. Please get to know your kit before you start building!
MULTIPLEX model kits are subject to constant quality checks throughout the production process, and we sincerely
hope that you are happy with the contents of your kit. However, we would ask you to check all the parts before you start
construction, as we cannot exchange components which you have already worked on. If you find any part is not
acceptable for any reason, we will readily repair or exchange it once we have checked its condition. Just send the
component to our Model Department, and be sure to include a brief description of the fault.
We are constantly working on improving our models, and for this reason we must reserve the right to change the kit
contents in terms of shape or dimensions of parts, technology, materials and fittings, without prior notification. Please
understand that we cannot entertain claims against us if the kit contents do not agree in every respect with the instructions
and the illustrations.
Caution!
Radio-controlled models, and especially model aircraft, are by no means playthings. To build and operate
them safely requires a certain level of technical competence and manual skill, together with discipline and
a responsible attitude at the flying field. Errors and carelessness in constructing and operating models can
result in serious personal injury and damage to property. Since we, as manufacturers, have no control over
the construction, maintenance and operation of our products, we wish to take this opportunity to point out
these hazards, and to emphasise your personal responsibility.

Important
For all joints involving the styrofoam wing and tail panels it is essential that you do not use solvent-based adhesives,
and in particular avoid instant or cyano glue (cyano-acrylate). If you use such materials they melt and destroy a large
volume of foam, and the component will be completely ruined. Use solvent-free adhesives, such as 5-minute epoxy or
white glue.
Using 5-minute epoxy (e.g. MULTIPLEX Z-Poxy, Order No. 59 2500)
This adhesive should only be used at room temperature. Its maximum working time („pot life“) is about 5 minutes, so
you should only mix up the quantity you need for the job in hand. Take great care to mix equal quantities of the two
components, and mix them up quickly and thoroughly. Apply the adhesive sparingly to one side of the joint, press the
parts together immediately and secure them with tape or clamps for at least 10 minutes. Excess resin can easily be
wiped off with methylated spirit, but only while still soft. Do not use any other solvent, as these materials tend to
attack and destroy the foam and ABS components of your model. Please read the glue manufacturer’s
recommendations.
