Preparations
Excenter assembly:
If not already performed, mount the excenters and pushrods. The larger pushrods are for the flaps, the
shorter ones for the ailerons. Pay attention to left and right servos. (Using two pins in the excenters is
sufficient, but to be on the safe side, also three pins can be used.)

Excenter mounting
Offsets: On the
ailerons, no mechanical offset
of the excenter and no electronic offset of the servo are
applied. Set the aileron servo position to 0 in the transmitter before mounting the excenter, such that the
pushrod pin is at 90° to the long side of the servo. You can slightly press the excenters on the drives by
hand and tighten them later.
At the
flaps an electronic offset
is needed to achieve full downward deflection. Recommended range (for
Graupner HoTT transmitter, for most other brands smaller values are sufficient):
Graupner
DS3288
65%-80%
MKS
DS6125mini 80%-85%
Futaba
S3150
Set these values in your transmitter and adjust the servos, before continuing.
