or installations with a high tank position. Not needed for fuel injection engines, which do this automatically.
Adjustability:
• Five-point curve allows adjustment of engine mixture at varied throttle settings.

• The CH8 knob adjusts the high throttle mixture (may be deactivated. see
AUX-CH
).
• Because both use CH8, this function cannot be used simultaneously with
AILEVATOR
.
• An acceleration (
ACCE
) function (
ACRO
only) helps the engine compensate for sudden, large amounts of throttle input by
making the mixture suddenly richer, then easing it back to the proper adjustment for that throttle setting. This function

on rapid throttle input.
• Separate curves are available (
HELI
only) for normal, idle-ups 1 and 2 combined, and idle-up 3. Immediately below
MIX
the radio displays the curve you are editing; ex:
>NORML
; and then which condition is currently active by your switches
ex: (
ID1/2
). Note that you can edit the mix for a different condition without being in that condition, to allow editing
without having to shut off the helicopter’s engine every time. Be sure you are editing the proper curve by checking the
name after the > and not the one in parentheses.
