Specification
Float length:
Overall width:
The robbe floats set is designed for the Air Beaver model
aircraft, but is also suitable for converting other models
of similar size and weight for flying from water.
Once the Beaver's standard wheeled undercarriage
has been removed, the floats assembly can be atta-
ched directly to the fuselage; no other modifications
are required.
It is also possible at any time to remove the floats
assembly and convert the model back to wheels again.
Sequence of assembly
Please study the illustrations and the brief instructions to
obtain a clear understanding of the individual stages of
construction.
Preparations
Carefully undo the undercarriage fairings and remove
them.

The converted model's Centre of Gravity should be
checked before the first flight.
Check all the control surfaces and the power system,

and ensure that the water rudders work correctly.

The model should be test-lown and trimmed properly
before it is itted with loats and lown from water.
Notes on flying the model; the first take-off from water
Observe all the safety notes, but please ensure in par-
ticular that you do not endanger any other users of the
water (bathers, boat operators, etc.).
For the irst few test-lights using the loats, seek out an
area of calm water of adequate size, and wait for a day
with little or no wind. The model is easy to manoeuvre
on the water thanks to the supplementary rudders atta-
ched to the loats.
Place the model in the water and open the throttle gra-
dually to taxi away from the bank. Switch off the motor,
and the model will automatically swing into wind (wea-

thercocking effect).
Open the throttle and allow the aeroplane to accele-
rate until it rises onto the step of the loats, and starts
planing.
Leave the elevator at the "neutral" position initially. Do
not apply up-elevator until you actually wish to lift off.
The increased drag caused by the loats causes the
Beaver to respond a little more slowly in the air, and it
will require a slightly higher throttle setting. Take this into
account when lying the model, and preparing for the
landing.
Allow the model to descend steadily by keeping power
on to a higher level than normal, and allow the aero-
plane to touch down smoothly on the water.
Bring the light to a close in good time, so that you have
enough residual current to taxi back to the bank.
At the end of the water lying session open the fuselage
and check for any water inside. Allow the model to dry
out if necessary.
From time to time check that the loats and rudder sys-
tem have not been damaged by lotsam in the water.
Undo the undercarriage retaining screws, and remove
the complete undercarriage.
