PROG MIX 1-6 – PROGRAMMABLE MIXES 1 through 6 (continued)
H-34
• Eliminate Pitch to Collective Trim Changes
(non CCPM only)
This is a condition when the Heli rolls left or right, or
pitches fore or aft when a collective input is given. This
is commonly caused by a mechanical geometry issue
in the design of the servo linkages and mechanical
mixers/levers. By using a program mix for Pitch-to-
Aileron to correct an Aileron trim change issue, the
mix will allow the Aileron servo to move slightly in the
opposite direction of the out of trim direction in order
to keep the helicopter from rolling, while Collective
pitch is added or reduced. This standard mixer would
designate the Pitch (Collective) as the Master and the
Ailerons as the Slave. For this type of Mix, you would
use Standard Program Mixes 3 through 6.
• Activating Retractable Gear via the Flight
Mode switch
This form of mix would allow you to activate your
retractable landing gear via your Flight mode switch.
It could be set so that in Normal (Hover) and Throttle
Hold (Hold) modes, the retracts would be down, and
when you move the Flight Mode switch to positions
1 or 2, the retracts would automatically go up and
stay up in these modes until you return to Normal or
Throttle Hold. This type of mix reduces the workload
on the pilot, so they can be more focused on flying
the model. This type of mix would use Multi Point
Programmable mixes 1 or 2, and would designate
FMOD (Flight Mode switch) as the Master and Gear or
another unused auxiliary channel as the slave.
The possibilities are endless and limited only by
the imagination.
