Refer to the plan and parts list constantly when building the model.
Note that balsa knives, pins, the ends of thin wire etc. have sharp points and edges; always handle
them carefully to avoid injury.
Keep tools, adhesives and paints out of the reach of children.
When using solvent-based glues make sure that your building room is well ventilated.
Take left-over paint and adhesives to your local toxic waste collection centre.
A large, unobstructed working area is a great advantage for all modelling activities.
If you are not sure of any procedure in building this model, ask the advice of an experienced model
builder.
If you have to handle lead ballast be sure to wash your hands thoroughly with soap and water
afterwards.
Flying the model
Never fly your CUMULUS XXL in a nature reserve or any other protected site. Please don’t disturb the
animals and plants which live in the countryside.
Trees and bushes are the natural habitat of many birds, and also serve as nesting sites and general
protection for them.
Exhausted dry cells and rechargeable batteries must not be thrown in the household waste, as they
contain toxic materials. Take all batteries back to the model shop, or to your local toxic waste
collection centre.

Note
Areas of the fuselage which are to be glued should be rubbed down with fine-grit abrasive paper to
remove any lingering traces of mould release agent. Aim at reducing the glossy surface to a matt
finish, especially when dealing with smooth, shiny GRP parts, otherwise there is little chance of a
durable glued joint.
Important: don’t use more glue than is necessary, as excess adhesive just adds unnecessary weight.
Please read the instructions supplied by the adhesive manufacturer before using any particular glue.
For more information on adhesives see the main FS catalogue.
