FMS Fox - Curve Flight Maneuvers; In-Flight Trimming Adjustments

c) 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 own at a constant altitude by gently pulling
the elevator control stick.
When the model is ying 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 ight height even in curves.
Important!
The rudder efciency depends on the deection path at the transmitter, as well as the ight speed. 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 own for a few hours.
Attention!
When ying, always observe sufcient minimum ight speed. With the motor off, 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, y at a sufcient safety height in the beginning in order to allow yourself to get used to the
steering attitude of the model. Do not y too far in order to be able to clearly evaluate ight attitude at all
times.
d) Trimming the Model in Flight
If your model tends to drift to one direction in straight ight, correct the neutral position of the corresponding rudder
by trimming at the transmitter.
• Rudder:
If the model drifts or „pushes“ towards the left, push the rubber trim lever to the right repeatedly until the model
ies 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 at angle at full motor speed and maintains the altitude with
the motor off. 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 ies straight. If the model turns towards the right, effect a trim correction towards the left.
• Wing aps:
The wing aps can be used to increase the sailing performance, as support of the ailerons or as a landing aid in
connection with the ailerons. With the wing aps set neutrally, there is no change to the ight properties.
