THR-HOLD : This function holds the engine in the idling position and disengages it from the THROTTLE STICK when
SWITCH E
Adjustability:
Range of -50% to +50% centered about the throttle idle position to get the desired engine RPM.
Assigned to SWITCH G (8JA) or E
Adjustable in the CONDITION SELECT ( THR-HOLD item).
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
° to +10 ° to +12 ° , is automatically activated with THR-HOLD .
Since revo. mix adjusts for torque from the engine, no revo. mix is
available for THR-HOLD .
Priority:
in the desired positions before trying to start the engine. (We recommend starting your engine in throttle hold for safety
reasons.)
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.
GOAL of EXAMPLE:
Set up throttle hold.
Determine desired throttle position of
the idling engine, turn on THR-HOLD , and
adjust percentage as required to reach
the desired running point.
Where next?
Prior to setting up THR-HOLD
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 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.
STEPS:
Open THR-HOLD function.
Activate the function.
Set desired engine position.
Close.
