Thr-Delay (Acro); Throttle-Needle Mixing (Acro/ Heli) - RadioLink AT9S Pro Instruction Manual

3.1.13 THR-DELAY (ACRO)

The THR-DELAY function is used to slow the response of the throttle servo
to simulate the slow response of a turbine engine. A 40% delay setting
corresponds to about a one-second delay, while a 100% delay takes about
eight seconds to respond. This function may also be used to create a
"slowed servo" on a channel other than throttle. This is accomplished by
plugging the desired servo (Ex: gear doors) into CH3 (THR), throttle into an
auxiliary channel such as 8, and then using some creative mixes.

3.1.14 THROTTLE-NEEDLE mixing (ACRO/ HELI):

THROTTLE-NEEDLE is a pre-programmed mix that automatically moves an in-flight mixture servo (CH8) in
response to the THROTTLE STICK inputs for perfect engine turning at all throttle settings. This function is
particularly popular with contest pilots who fly in a large variety of locations, needing regular engine tuning
adjustments, and requiring perfect engine response at all times and in all maneuvers. Also popular to
minimize flooding at idle of inverted engine installations 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 in-flight mixture servo must connect to receiver CH8.
• In-flight mixture servo may also be used as a second servo for tuning a twin.
