When the end of the trim range has been reached, the signal sounds go out. If the trimming button is then deflected
in the opposite direction and held, the signal sounds sound again.
When the middle position of the trimming range has been reached, the remote control issues a longer signal sound.
(Symbol arrow) Now set the middle position of the trim for all four channels. The set trim value is automatically saved
in the remote control and is retained even after switching it off and on.
e) Servo-Reverse and Delta Mixer Functions
The remote control "HT-4" has a servo reverse function and a delta mixer function (MIX).
The servo reverse function can switch the running direction of the servos.
The delta mixer function is needed for flight models with delta wings.
For operation of the racecopter, all servo reverse switches (figure 2, item 8, 9, 10, 11) and the switch for the
delta mixer function (figure 2, item 12) must be at the bottom (label "NOR.").
