Two models from Graupner on this page.
Firstly an unusual model that is boat and
plane - the HYDROPLANE 3D.
The model resembles a typical fast racing
hydroplane design, but has 2 sets of
elevons at the tail (stern?) that are
interconnected. It also features twin air
rudders. Manoeuvrability on water is
unlikely to be brilliant, but this is a very
different model..
The Hydroplane 3D is 79cm
(31”) long, 55cm (21½”) wide
and 22cm (8½”) high. The
flying weight is around 235g
(8¼ oz.) giving a wing loading
of only 11.9g/dm 2 (3.9 oz./sq.ft.)
It is quick and easy to assemble from vacuum-moulded and laser-cut Depron ®
components. The reinforcing struts are lightweight, high-strength CRP profiled
strips, ensuring a low all-up weight. To complete the model you’ll want a 280
class brushless motor, a suitable 10A controller, propeller, a 3s LiPo pack between
350mA and 650mA and 3 mini-servos.
The Hydroplane 3D should be available through your local model shop or any of
the internet model shops. The cost of the kit should be around £60.
The second model is the Graupner
SPEED CAT. The Speed Cat is a pylon
racer of all-GRP construction. All the
model´s components, i.e. fuselage, onepiece
wing, tailplane & wheel fairings,
are supplied ready-made moulded items,
high-gloss , painted in the mould.
The key features of the Speed Cat are
its beautifully, harmonious, lines and distinctive “apple cheeks”, which give the
model an interesting semi-scale appearance. The model is capable of very high
airspeeds, especially electric powered. The aerodynamic layout of the Speed Cat
gives the model pleasantly stable flying characteristics, and any RC pilot with
average flying skills will not find it difficult to control.
It features aileron, elevator and throttle control, has a span of 101cm (39¾”) and a
wing area of 18.8 dm
E.F.-U.K. 29
2 (290 sq.in.). The target flying weight is 1.2kg (2 lb. 10 oz.)
using a 500 size brushless motor and 3s LiPo with 40A ESC. Also included are the
pre-formed aluminium undercarriage, 2 foam wheels, plastic spinner, small items,
decal sheet & linkage pack. Price around £150 from local model shops/internet.
