THR-HOLD
: This function holds the engine in the idling position and disengages it from the THROTTLE STICK when
SWITCH E (10CHG) or G (10CAG) is moved. It is commonly used to practice auto-rotation.
Prior to setting up THR-HOLD, hook up the throttle linkage so that the carburetor
is opened fully at high throttle, then use the digital trim to adjust the engine idle
position. To have THR- HOLD maintain idle, move the THROTTLE STICK to the
idle position, then move the hold SWITCH on and off and keep changing the
offset value until the servo does not move. To lower the engine idle speed, or if
you want to shut the engine off, input a higher negative number.

Adjustability:
• Idling position: Range of -50% to +50% centered about the throttle idle position to get the desired engine RPM.
• Switch assignment: Assigned to SWITCH G (10CAG) or E (10CHG) down.
• Idling position: Range of -50% to +50% centered about the throttle idle position to get the desired engine RPM.
• Switch assignment: Assigned to SWITCH G (10CAG) or E (10CHG) down.

• Throttle curve: Since the throttle is moved to a single preset position, no curve
is available for THR-HOLD.
• Collective pitch curve: Independent curve, typically adjusted to create a blade
pitch range of -4% to +10% to +12%, is automatically activated with THR-

• Revo. mix: Since revo. mix adjusts for torque from the engine, no revo. mix is available for THR-HOLD.

reasons.)
• Gyro: Gyro programming includes an option to have a separate gyro setting for each condition, including THR-HOLD.
This avoids the potential problem of the user being in the wrong gyro setting when going to THR-HOLD, resulting in an
improper rudder offset and the model pirouetting.
