d) Curve Flight
Spiralling is initiated with the aileron; the model angles to the side. If the model has reached the desired declination,
the aileron is returned back into centre position. Now, the curve can be flown at a constant altitude by gently pulling
the elevator control stick.
When the model is flying in the desired direction, a quick regulation of the aileron into the opposite direction will
bring the model back to a horizontal position and also return the elevator to the centre position. Try not to take too
narrow curves in the beginning and observe even flight height even in curves.
Important!
The rudder efficiency depends on the deflection path at the transmitter, as well as the motor performance.
The higher the motor speed, the narrower curves can be flown. If you do not take back the aileron in time
after initiating a curve, the model will roll or turn onto its back. Practice controlling a roll only for having
flown for a few hours.
Attention!
When flying, always observe sufficient minimum flight speed. With reduced motor output, pulling on the
elevator control lever too much will cause the model to slow down and top forwards over the fuselage top
or to the side over a wing.
Therefore, fly at a sufficient safety height in the beginning in order to allow yourself to get used to the
steering attitude of the model. Do not fly too far in order to be able to clearly evaluate flight attitude at all
times.
e) Trimming the Model in Flight
If your model tends to drift to one direction in straight flight, correct the neutral position of the corresponding rudder
by trimming.
• Rudder:
If the model drifts or „pushes“ towards the left, push the rubber trim lever to the right repeatedly until the model
flies straight. If the model drifts towards the right, effect a trim correction towards the left.
• Elevator:
Set the elevator trim lever so that the model rises in a flat angle at full motor speed and maintains the altitude at
reduced motor speed. If the model rises too much, push the trim forward. If the model tries to dip down with its tip
all the time, push the trim backwards.
• Aileron:
If the model turns to the left along the longitudinal axis, push the aileron trim lever to the right repeatedly until the
model flies straight. If the model turns towards the right, effect a trim correction towards the left.
