Sukhoi SU 31—2.75m/2.6m Page|3
You have acquired a kit, which can be assembled into a fully working R/C model when fitted out with suitable accesso-
ries, as described in the instruction manual with the kit. However, as manufacturers, we at Composite-ARF are not in a
position to influence the way you build and operate your model, and we have no control over the methods you use to
install, operate and maintain the radio control system components. For this reason we are obliged to deny all liability
for loss, damage or costs which are incurred due to the incompetent or incorrect application and operation of our prod-
ucts, or which are connected with such operation in any way. Unless otherwise prescribed by binding law, the obliga-
tion of the Composite-ARF company to pay compensation is excluded, regardless of the legal argument employed.
This applies to personal injury, death, damage to buildings, loss of turnover and business, interruption of business or
other direct and indirect consequent damages. In all circumstances our total liability is limited to the amount which you
actually paid for this model.
BY OPERATING THIS MODEL YOU ASSUME FULL RESPONSIBILITY FOR YOUR ACTIONS.
It is important to understand that Composite-ARF Co., Ltd, is unable to monitor whether you follow the instructions con-
tained in this instruction manual regarding the construction, operation and maintenance of the aircraft, nor whether you
install and use the radio control system correctly. For this reason we at Composite-ARF are unable to guarantee or
provide a contractual agreement with any individual or company that the model you have made will function correctly
and safely. You, as operator of the model, must rely upon your own expertise and judgement in acquiring and operat-
ing this model.
Personal safety:
There are a couple of things that are good to keep in mind when you are assembling your Sukhoi SU-31. Some of
them are common sense, but it doesn t hurt to be reminded. While you are working with tools and sharp implements,
be aware of others around you and the environment you are working in. Always wear eye protection, and when work-
ing with solvents and glues, keep your area ventilated. When cutting or sanding materials, always wear a face mask to
avoid inhaling particles. Keep your work environment clean and tidy at all times. A clean workshop will enhance the
experience. Protect all parts from scratches and dents. Use rubber matting on your bench, and be careful of compo-
nents like screws getting between the part you are working on and the bench.
Assembly process:
This assembly manual is set out in an order that simplifies the process. Each step is in an order that leads into the
next. You may wish to change and do some things in a different order, which is fine provided you keep in mind that
some things need to be done before some others. When planning out the installation of your components, always keep
the centre of gravity location in mind. If you plan ahead you can avoid having to add weight to your model. It is far eas-
ier to remedy a nose heavy model than a tail heavy model. A few grams of lead at the rear is preferable to hundreds of
grams in the nose! You will find that it is easiest to fit items that cannot be relocated, like aileron and elevator servos,
before you do a preliminary C of G check. Rudder servo(s), RX and ignition batteries etc can generally be relocated to
suit your requirements.
Most of all, enjoy the process of creating your new Composite Arf Sukhoi SU-31, a job well done is always satisfying!
