The Throttle Delay function is used to delay the response of the throttle servo to
simulate the slow response of a turbojet engine to throttle control. A 40% delay
setting corresponds to about a one second delay, while a 100% delay takes about eight
seconds to respond.
Setting Throttle delays
Turn the TH-DLY function ON by pressing the (+)
key ("ON"displayed ). Turn off (INH) the function
with the (-) key.

The throttle needle mixing function is used to control the motion a second servo
connected to the mixture control system of an engine (needle valve or other mixture
adjustment) relative to throttle stick movement. The throttle needle servo connects
to receiver CH8, and the CH8 control knob adjusts the high throttle mixture. An
acceleration function moves the engine mixture control when the throttle is moved.
This function cannot be used simultaneously with the Ailevator function.

1. Turn the TH-NDL function ON by pressing the (+) key
("ON" displayed). Turn off (INH) the function with the (-) key.

2. Delay rate setting
Set the amount of delay with
the (+)/(-) keys. A 40% value
delays the response by 1
second. (You may reset to
zero by pressing the (+)/(-)
keys simultaneously.)
2. Input 5-point curve values
Move the throttle stick to the
position you want to set (the
adjustment point is displayed at the
bottom left corner of the screen)
and set the rate with the (+)/(-)
keys.
• If you're unhappy with what you've
set, you may return to the default
value by pressing the (+) and (-)
keys simultaneously. Initial values:
POS1 = 0%
POS2 = 25%
POS3 = 50%
POS4 = 75%
POS5 = 100%
3) Acceleration function
setting
Input the desired acceleration
level with the (+)/(-) keys. You
can reset it to the initial value
by pressing the (+)/(-) keys
simultaneously.
