The First Flights, Flying In - ROBBE Arcus II Series Instruction And User's Manual

The first flights, flying in

Always stand behind or at right angles to the model to avoid wrong control
commands.
With calm steering movements you slowly get used to the model. With changing flight
directions you can practice curves, ovals and circles.
Tip:
If the model flies towards you with its nose, the functions (except elevator and
speed control) are reversed.
Always refer to the Flight Preparation section!
Starting
Models with undercarriage can be started from the ground or, depending on the size
of the model, also from the hand.
Models without undercarriage can be started from the hand.
The correct take-off procedure must always be adapted to the model and the flight
characteristics of the airfield.
When starting models with landing gear from the ground, a few short roll tests are
carried out before the start to make sure that the model does not get stuck.
A helper should be present for the hand start, who can transport the model into the
air with not too little thrust.
Bring the engine speed to full power and start the model against the wind.
When launching models with landing gear from the ground at sufficient speed, lift the
model off the ground with a short elevator deflection.

Trimming
The model must be trimmed so that it adopts a stable flight attitude. If necessary, the trim
buttons of the remote control system can be used to slightly trim the model. The trimmings
should be carried out at a sufficient safety height.
For larger trim interventions, either the boom length or the servo centre position should be
adjusted via the transmitter after landing.
To do this, the trim adjustment must be removed using the trim buttons on the remote control
system.
After the correction has been made, check the trim with another flight.
Landing
The landing shall be initiated with sufficient speed. Care must be taken to avoid a
stall. The minimum flight speed should be flown at a sufficient safety altitude.
On models without landing gear, make sure that the propeller has come to a
standstill before landing. This avoids damage to engine and propeller.
On models with landing gear, carefully put on the model with a little drag throttle,
then reduce the engine speed to zero.
Notes on the flight battery
When the motor power decreases, land immediately and disconnect the battery
from the controller. Do not empty the battery, otherwise it will be deeply
discharged and permanently damaged. Let the battery cool down before
recharging.
Replacing the prop
A damaged prop must be replaced immediately!
Please observe the safety instructions on pages 2 and 3!
