GRAUPNER mx-20 Hott, Programming Manual

268 Detail program description - Control adjust
Eight-fl ap wing
By standard the
mx-20
HoTT supports the
comfortable control of up to eight servos for the aileron/
camber changing fl ap functions.
In the following we will consider a model without motor
drive and without spoilers in the wings. The example
is also based on the assumption that you have already
mechanically preadjusted the model and you have
already ensured the correct defl ection of all rudders or
checked this again in the scope of this programming
and made adjustments, if applicable, through servo
switching at the receiver and/or through the "Servo
adjustment" menu.
The servos should be connected to a suitable receiver
as follows:

6 12 11

For the control of all fl aps, up to two additional
proportional rotary controls are required in addition to
the two joysticks or, alternatively up to two two-stage
switches (SW).
In order to be able to control all servos, fi rst switch to the
menu …
