Practical advice:
Beginners in particular are urgently advised to reduce the directness of the control command with which the Quadro-
Copter performs the commands from the remote control around the centre detent (negative exponential or „expo“).
To illustrate:
Normally, the QuadroCopter responds linearly. This means that the pilot stick deflection and the reaction are synchronous.
With negative expo, the QuadroCopter will respond relatively sluggishly at the start of the controlling motion. In the
case of stronger control deflections, however, it responds much more strongly to the control command. This is particularly
beneficial for beginners who initially tend to oversteer, i.e. move the control stick of the remote control more intensely
than necessary. This effect is, of course, only desired for the three control axes (roll, pitch and yaw) and not, however,
for throttle. Observe: Do not configure expo on throttle.
In other words: With negative expo, slow behaviour of the flying device is achieved on the controlling motions in the
area of the centre detent of the pilot stick. This takes place either via the optionally available software, via the
QuadroCopter’s switches (see „beginner mode“) or via the existing „expo function“ of the remote control. Only
computerised remote controls can set „expo“. However, care must be taken, since the higher the negative expo
selected, the more aggressively the QuadroCopter reacts when the control stick is moved in the area of full deflection.
For the „user“ flight mode, you must configure your own setting with the optionally available configuration
software. For this, you can use either the beginner or sport modes as a basis and customise your own
personal requirements. Please observe the operating instructions for the configuration sets.
i) Configuration with PC Software
To fly the QuadroCopter with your own settings, you may connect the electronics system of the QuadroCopter to a PC
via an interface cable (serial TTL on USB).
An optional PC configuration set is available for this. This contains a connection cable, a detailed description and the
software on CD. This kit may be used with Microsoft® Windows XP®*, Windows Vista®* and Windows 7®* (* Micro-
soft, Windows XP, Windows Vista and Windows 7 are registered trademarks of the Microsoft Cooperation in the U.S.
and other countries).
As it is not necessary to carry out configuration with a PC for normal flight operation, this is only mentioned here as a
side note.
When the DIP switch 3 is set to „ON“, the QuadroCopter is in PC configuration mode (PC mode) and cannot be flown.
For more information on the configuration of the connection to the Flight Control „QC 09“ and the programming, see
the software’s operating instructions.
In PC mode (also called „Bootloader operation“), the green „LED1“ must flash continually at approx. 1 Hz. The red
„LED2“ flashes at a quick, irregular rhythm during communication with the computer.
