N-Th Normal Throttle Curve; N-Pi Normal Pitch Curve; I-Th Idle-Up Throttle Curve Function - FUTABA 6EXHP Instruction Manual

N-TH Normal throttle curve function
Used to set throttle curve for normal flight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine
RPM for consistent load on the engine. Throttle curve can be adjust from 0-100% each point.
This normal throttle curve create basic curve for around hovering. Use this function together with the normal pitch curve (see
Normal pitch curve) so that up/down control has a constant engine speed.
To set the normal throttle curve:
1. Enter the programming mode and use the MODE key to access the "N-TH" function.
Throttle stick position number will appears on left side of display and "%" symbol will be
flashing.
2. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttle
stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi)
position.
3. Push up or down DATA INPUT lever to set the servo position.
4. Use SELECT key to set other points with same manner.
N-PI Normal pitch curve function
Used to set pitch curve for normal flight. 5-point pitch curve is utilized to best match the blade collective pitch to the engine
RPM for consistent load on the engine. Pitch curve can be adjust from 0-100% each point.
This normal pitch curve create basic curve for around hovering. Use this function together with the normal throttle curve so
that up/down control has a constant engine speed.
To set the normal pitch curve:
1. Enter the programming mode and use the MODE key to access the "N-PI" function. Throttle
stick position number will appears on left side of display and "%" symbol will be flashing.
2. Use SELECT key to select the desire curve point. Point 1 is shown initially which is throttle
stick all the way downward (slow) position. Point 5 is throttle stick all the way upward (hi)
position.
3. Push up or down DATA INPUT lever to set the servo position.
4. Use SELECT key to set other points with same manner.

I-TH Idle-up throttle curve function

Used to set throttle curve for idle up flight. 5-point throttle curve is utilized to best match the blade collective pitch to the engine
RPM for consistent load on the engine when idle up function is on. Throttle curve can be adjust from 0-100% each point.
This idle up throttle curve is to set for consistent engine RPM and can be activated at any time when mid air maneuvers are
executed, such as loops, rolls, and 3D flight even when reduced the blade collective pitch.
To set the idle-up throttle curve:
1. Enter the programming mode and use the MODE key to access the "I-TH" function.
2. Push the DATA INPUT lever upward. This will cause the flashing "INH" display to change
to a flashing "ON" display. Now the I-TH function is on. Push the SELECT key, throttle stick
position number will appears on left side of display and "%" is blinks.
