Control Centering

• Make sure servo directions (reversing) on your transmitter are

correct. Ensure control surfaces move freely by performing a
Control Test.

• Make sure trim and sub-trims are set to zero.
• Make sure the servo arms are set to 90 degrees. If not, remove

a servo arm and put the arm in a spline position closest to the
90 degree position (perpendicular to the servo’s long axis). If 90
degrees exactly cannot be reached, use the sub-trim on your
transmitter to adjust the servo arm to the 90 degree position.

• The Vectored-Thrust (VT) servo arm is neutral at the 11:30

position (on a clock face) (A) when looking down from above
while standing at the rear of the airplane. This neutral position
gives the VT servo maximum throw in both directions.

Elevons and Rudder Centering

The center for the elevons is alignment with the trailing edge of the fuselage between the rudders.
The center of the rudders is alignment with the center of the vertical fi n to which the rudder

is attached.

Vectored-Thrust Centering

CAUTION: Always disconnect the fl ight battery from the ESC before handling the propeller or

injury could result.
• Turn the propeller to horizontal on the model.
• From above the model, measure from the right end of the propeller (leading edge tip (B) to the center

of the back of the canopy (C).

• Measure from the left end of the propeller (leading edge tip (D)) to the center of the back of the

canopy (C).

• These two measurements (A to B and B to C) are the same distance when the VT unit is centered.

Nose Gear Centering
• The center for nose steering occurs when the model follows a straight path while the rudder input is

at neutral.

TIP: When needed, turn the ball link or clevis until the control surface is at the center position
(up/down or left/right).

Refer to your transmitter’s manual for instructions about making adjustments to control surfaces,
Sub-Trim and Reverse.

After binding a transmitter to the model receiver, set trims and sub-trims to 0,
ensure servo arms are in the correct positions, then adjust clevises or ball links
to center the control surfaces.

Tip: Turn the clevis or ball link clockwise or counterclockwise on the linkage.

1

Adjusting a Clevis

• Pull the silicone tube from the clevis to the linkage.
• Carefully spread the clevis and put the clevis pin in a selected hole in the
control

horn.

• Move the tube to tighten the clevis on the control horn.

2

Adjusting a Ball link

• Connect the ball link to the ball installed on the control horn using pliers or

ball link pliers.

• Install the linkage in a hole in the servo arm using a link cover.
