Examine your kit carefully!
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 correct or exchange it. Just send the component to our Model
Department. Please 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. Building and
operating 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 building and flying the
model 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 are obliged to take this
opportunity to point out these hazards, and to emphasise your personal responsibility.
