Tooth Backlash:
A correct adjusted tooth backlash between the motor pinion and the main gear is very important to have a smooth running and
efficient helicopter. The space between the motor pinion and the main gear must be between 0.05mm and 0.1mm.
Linkage Rods main rotor head:
The distance between the ball links on the linkage rods must be 63mm. If the space is not equal on both linkage rods, the
main blade tracking will be not correct.
Ball Links
If there are linkages which run hard, you can press the ball links slightly with a plier. Alternately the ball links can
also be reamed out with a special ball head reamer.
Center of gravity (CG)
The CG of an RC helicopter should be at the main shaft's position, to ensure the best flight performance. As long as the helicopter
is only used for hovering or basic flight, an slightly incorrect CG is not a big problem. If the CG is too different from the main shaft
position, the helicopter won't perform well in 3D flight. To check the CG take the helicopter with mounted battery and canopy on
the main rotor shaft and turn it 90° to the side. The helicopter should stay in a horizontally position without moving the front or
the tail more than 60° to the ground. If the helicopter turns more than 60°, adjust the position of the battery on the battery plate
until the the helicopter stays horizontally.

This part of the manual will guide you through the programming of your helicopter. Please do the whole programming step by step
according to this programminng guide, to achieve the best result.
Preparation:
WARNING: Disconnect the motor and the ESC while the whole programming!
l

Terminal
After connecting the terminal unit (Art. Nr. 08.FBL-DSP) with the running FBL-3X, the "Welcome" menu will appear. There you can
see the current software version of your FBL-3X. You can navigate and change values with the four arrow keys of the terminal.
By pressing the keys you can switch between the main menus. By pressing once you can enter the choosen menu and you will
see the values which can be changed. Most menus have more than one changeable value. You can switch between the values by
pressing repeated. By pressing the key you can exit the sub menu.
Values can be changed with the keys
Safe Settings
After changing values in the FBL-3X system, you must safe them. Press and hold in any main menu (except channel monitoring) first
and then . You will see "ALL PARAMETERS SAVED".
WARNING: If you want to cancel the changes, it is not sufficient to remove the terminal. You must disconnect the power from the
FBL-3X to cancel all unsaved settings.
WARNING: The terminal must be removed before flying the helicopter!
