We recommend a receiver battery of at least 3 Ah capacity, which should be properly
prepared before use and maintained during its life, i.e. the pack must be charged and
discharged (cycled) several times before it reaches its full stated capacity.
We deliberately recommend the use of rechargeable batteries for the receiver and
transmitter, as they offer the widest margin of safety in use.
Please see the main GRAUPNER FS catalogue for details of suitable chargers.
Use foam rubber to pack round the receiver.
Assembling the ASW 28
Please don’t start work on the model until you have read through the instructions and
have a clear understanding of the purpose of the various components and the in-
dividual stages of construction. If you are not satisfied with the quality of any part,
take it back to your model shop for replacement before modifying it in any way.
These instructions describe the construction of the model including the installation of
the retractable motor, Order No. 6097. If you do not intend to fit a power system, i.e.
you prefer to build the model as a pure glider, you should simply ignore these stages.
The fuselage
Thoroughly sand all the joint areas inside the fuselage until they have a matt ap-
pearance (see the note following the Adhesives table).
Before you start construction you have to decide whether to install a retractable
wheel or not. If you are fitting a retractable motor, a retractable wheel is essential.
If you intend to complete the ASW 28 as a pure glider, cut the wheel doors out of the
fuselage using a fine-blade piercing saw; the outline of the opening is marked on the
underside of the fuselage.
However, if the model is to be fitted with a retractable motor, the wheel doors need to
be moved forward by about 60 mm, and should be about 110 mm long overall.
Before cutting out the wheel doors, drill four 1 mm Ø holes on the marked transverse
lines at both ends, spaced about 22 mm from the fuselage centreline. Fit short steel
pins through these holes, projecting on the inside, and place the aluminium tubes
