GRAUPNER mc-16 Programming Manual page 294

If everything is correctly set so far, only the motor
is controlled with the C1 stick in the "Normal" flight
phase, whereas this should be switched off in the flight
phase "landing" (Servo 1 in »Servo display« inde-
pendent of "Throttle min front/rear" to -100 % or ad-
equately for a servo travel setting deviating by 100 %,
if necessary). In this flight phase the C1 stick then only
controls the raising of the ailerons and, if applicable,
the lowering of the flaps with the neutral point in the C1
control position selected per offset.
