GRAUPNER mx-20 Hott, Programming Manual

Page: 59 / 296

59 Helicopter models
Notice for those transitioning from older Graupner
systems:
In comparison to previous receiver layouts, servo
connector 1 (pitch servo) and servo connector 6
(throttle servo) have exchanged places. Servos
must
be connected to receiver outputs as illustrated at the
right in the bottom fi gure. Outputs which are not used
are simply left empty. More details about respective
swashplate types can be found on page 86 in the
"Basic settings" menu.
Installation notices
Servos MUST be connected to the receiver in the
sequence illustrated here.
Outputs which are not used are simply left empty.
Also be sure to follow the notices on the next pages.
Notice:
A speed regulator is also to be connected to receiver
output "6" in order to take full advantage of the throttle
limiter's convenience and safety features, see text
beginning on page 104. See page 169 about this.

… so only these menus need to be dealt with to program
a helicopter model.
