19.3.1 Replacing propellers
Observe the rotating direction of the respective motor and
the choice of the corresponding propeller without fail.
If these are incorrectly chosen, the model will not be able to
fly and will act in an erratic way when started again!
Loss of guarantee/warranty! The rotating direction is
marked on the propellers (”L” or ”R”). The mark ”L” or ”R”
points up. The propellers marked ”L” must be installed on
the motors that turn LEFTWARDS (counter clockwise). The
propellers marked ”R” must be installed on the motors
that turn RIGHTWARDS (clockwise).
