Hovering Throttle Adjustment Knob

Hovering Pitch Adjustment Knob

The Hovering Throttle knob may be used to "tweak"

the throttle servo's position around hover without affecting

main rotor pitch. It's handy to make up for changes in

rotor speed caused by variations in temperature, humidity,

The Hovering Pitch

knob may be used to

trim the collective pitch

near hover without

affecting throttle. Like

hovering throttle, it's

handy to make up for

changes in rotor speed

caused by variations in

temperature, humidity, or

other conditions. You can adjust the hovering pitch value

simply by turning the Hovering pitch knob VR2. Like

hovering throttle, this knob only works near hover and

tapers off at either end of throttle. Please center this knob

before you set neutrals or input throttle curves.

reversed in front of the percentage value. Now the

swash should properly respond to collective. If you've

done the wrong thing, you can reset the percentage by

pressing the Active/Inhibit (Clear) key.

6. If all the servos tilt the swash to the right with right

aileron stick, go to the next step. If they tilt the swash to

the left, press the Cursor Right key once to get to the

aileron setting menu (the arrow appears over the

number 1). Reverse the sign in front of the percentage

with the Data -Decrease key. Now the swash should

properly respond to aileron.

7. (120' swash only) If all the servos tilt the swash back

with up elevator stick, go to the next step. If they tilt the

swash forwards, press the Cursor Right key once to get

to the elevator setting menu (the arrow appears over the

number 2). Now press the Data -Decrease key until the

sign is reversed in front of the percentage value. Now

the swash should properly respond to elevator. (In the

180' swash menu, there is no elevator setting, and this

step should be skipped.)

8. Double check that all three functions, collective,

aileron, and elevator, produce the desired result on the

swashplate.

or other conditions.

To change the hovering

throttle setting, simply

turn the Hovering throttle

knob VR1. As shown in

the figure, turning the

knob has the largest effect

in the hovering region and

leaves the endpoints alone.

Please center this knob

before you set neutrals or input

throttle curves.

This procedure assumes helicopter is trimmed for hovering. Trimming must be done in near-calm conditions.

Repeat tests several times before making adjustments. If any changes are made, go back over the previous steps

and verify, or further adjust as necessary.

Test Procedure

Fly the model straight and level into

the wind at 100 ft altitude, lower

pitch to 0

Bring the helicopter into hover, add

full pitch and ascend 75 ft

Begin Down RVMX mixing with same

number as UP mix. From inverted

flight (top of loop, or mid-point of roll,

or inverted part of split-S), add full

negative pitch.
