16. Information for First Take-Off
a) General Handling
A QuadroCopter is essentially equipped with the handling of a normal helicopter. The differences, however, are in the
detail. For helicopters, the torque balance is stabilised by special gyros (in the yaw function). For this, there are two
different systems: “Normal gyros” or gyros with the “heading lock” function.
Normal gyros stabilise (cushion) the tail rotor against tipping motions which are caused by the pilots (driving speed
and/or pitch changes and/or external influences (e.g. side wind). A gyro with “heading lock” function has a “holding
action” against these tipping motions. Both systems respond to a control command – e.g. “yaw to the left” and subse-
quent neutral positioning with the immediate stopping of the tipping motion.
In your QuadroCopter – unlike in standard helicopters – there are three gyros installed for the yaw, pitch and roll
functions. The installed gyros are – in comparison with standard gyros – neither to be described as “normal gyros” nor
with “heading lock” function.
The gyros in the QuadroCopter are linked together so that after the end of a control command the QuadroCopter
always attempts to reach neutral position (hovering flight). Of course, how well this works depends on the space
available, the flight speed and/or the prevailing flight condition, the trim values of the QuadroCopter and external flight
conditions e.g. wind.
The flight control "QC 09" installed in the QuadroCopter has high-quality MEMS sensors installed. This achieves
relatively easy-to-control flight characteristics similar to those of a coax helicopter. The QuadroCopter agility is limited
by these sensors, however.
Activating the "agility mode" function limits the Flight Control sensors in their functions. The QuadroCopter can be
controlled much more agile around all axes in this mode. The flight characteristics are now closer to those of a helicop-
ter. Simple freestyle flight (looping, rolls) is possible as well.
The flight characteristics with active "Agility mode" function are not suitable for beginners. If you do not
have enough experience with flying QuadroCopters and/or helicopters, we recommend that you be very
careful during your first flights with active "agility mode".
b) Starting the Motor
Important!
Before switching on the transmitter, please set the throttle stick to “motors off” and all trim levers of the pilot
stick to zero (mid trimming). Otherwise, the QuadroCopter may not recognise the transmitter after the
battery is connected.
• After the flight battery is connected, the LEDs indicate “ready to fly”.
• THROTTLE to zero, YAW to full deflection to the left, PITCH and ROLL to neutral (also see figure 10)
• Rotors start to turn and start idle speed
• Red LED lights permanently and the green LED flashes (“motors on”)
• Increase THROTTLE slowly for lift-off (hovering flight)
