Preface

Despite precise laser cutting technology, material-related thickness fluctuations can make it difficult to connect. Please do not try to use force, slightly grind
affected components to enable easy connection.
,
These building instructions describe the step-by-step construction of the model in key words and should also be sufficient for less experienced
model builders to be able to build the model without any problems. Therefore, read
the entire building instructions carefully before starting construction
in order to get an overview of the individual assembly steps.
Motor frames with the corresponding hole pattern are included for the drive we propose. If other drives are used, these parts must be changed at your own
discretion.
Of course, the enclosed construction plans are indispensable for construction, in which each individual part is shown, some of them on a 1:1 scale.
As usual, the drive battery is only attached with Velcro and can be moved to achieve the correct center of gravity. If the battery
weight is less than around 190g, the nose of the fuselage must be trimmed accordingly with ballast.
Gluing should be carried out with the adhesives shown in the photos, so it makes sense, for example, to “staple” with thin superglue and later “glue” it with
wood glue. The additional weight we determined for this construction method is only for the entire model after it has dried about 35 g and provides significantly
greater stability.
Which decor you would like to equip your model with is up to you. You can contact us at any time about your individual decor wishes and we can also realize
that for you.
Please be sure to follow the assembly sequence described and
have the relevant components installed.
All we can wish for you now is a lot of fun building and especially flying our Bristol Scout.
Individual plug-ins and fits also prevent incorrect assignment.
Please be sure to pay attention to the setting values for the center of gravity and the rudder deflections given at the end of the construction instructions... it is better
to set them a little more conservatively at the beginning.
You should always only remove the components from the boards that are required for the upcoming construction phase. This prevents unnecessary
sorting and helps to keep an overview.
Once you have the plane under control, you can do whatever you want in the air, the stability knows no limits even in the most extreme flight
operations... and the Scout can easily handle even a somewhat rough landing thanks to its robust construction.
Material-related dimensional fluctuations in the construction plans cannot be completely ruled out; the following applies here: the component is absolutely the
right size. During assembly, plans should be protected with transparent PE film to protect against sticking.
otherwise it is not guaranteed that the sequence will change if the order is changed
All components are listed again in the parts lists.
