Control Surface Centering

After assembly and transmitter setup, conﬁ rm that the control surfaces are centered. The

model must be powered up bound to the transmitter in AS3X mode, with the throttle left at

zero. When enabled, SAFE mode is active at power up. AS3X mode is activated when the

throttle is raised above 25% for the ﬁ rst time after being powered on. It is normal for the

control surfaces to respond to aircraft movement if the aircraft is in AS3X or SAFE modes.

1. Verify the trims and subtrims on your transmitter are zero

2. Power up the model in AS3X mode and leave the throttle at zero

NOTICE: Be aware of the pushrod bottoming out in the ball linkage. Do not thread the

pushrod too far into the ball link or the pushrod will damage the ball link and protrude

into the area needed for the control ball.

3. Center the rudder with the rudder ﬁ llet. If adjustment is required, turn the ball link

on the linkage to change the length between the servo arm and the control horn

until the edge of the rudder is aligned with the rudder ﬁ llet.

4. With the ﬂ ap switch in the up position, center the ﬂ aps by aligning the inboard end

of the ﬂ ap with the wing ﬁ llet. Adjust the linkage length as in step 3 as necessary.

5. Center the ailerons by aligning the inboard end of the aileron with the ﬂ ap. Adjust

the linkage length as in step 3 as necessary.

6. The center position for the elevator should be trimmed

slightly down from

neutral (approximately 2mm) when the CG is in the middle of the recommended

range.

Adjust the linkage length as in step 3 as necessary.

Initial Flight Setup

If this is your ﬁ rst EDF jet model, or if you’d like to further enhance the upright

low-speed handling for the ﬁ rst few ﬂ ights, we recommend putting some upward

reﬂ ex in the ailerons to add washout to the wing. This will help to further minimize

and prevent tip stalls when ﬂ ying upright at low speeds, especially when landing.

Change back at any time before later ﬂ ights.

To add reﬂ ex:

1. Ensure the ﬂ aps and ailerons are properly centered.

2. Disconnect the ball link from the aileron control horn.

3. Rotate the ball link out 2 full turns (counter-clockwise).

4. Re-connect the ball link to the aileron control horn.

5. Repeat steps 1-5 for the other aileron.

6. Verify both ailerons have the same amount of reﬂ ex, approximately 2mm, when at neutral.

WARNING: Ensure there are still sufﬁ cient threads securing the ball link on the

pushrods. Un-threading the ball link too far will cause the control surface to fail

and in that situation the aircraft may suffer from ﬂ utter and/or be uncontrollable in ﬂ ight.

SAFE

Select Switch Designation

SAFE

Select technology can be assigned to any open switch (2 or 3 position) controlling a

channel (5–9) on your transmitter. Once assigned to a switch, SAFE select ON gives you the

ﬂ exibility to choose SAFE technology or AS3X mode while in ﬂ ight. If the aircraft is bound with

SAFE select OFF, the aircraft will be in AS3X mode exclusively.

IMPORTANT: Before assigning your desired switch, ensure that the travel for that channel

is set at 100% in both directions and the aileron, elevator, rudder and throttle are all on high

rate with the travel at 100%.

CAUTION: Keep all body parts well clear of the propeller and keep the aircraft

securely restrained in case of accidental throttle activation.

TIP: SAFE Select is assignable on any unused channels 5–9. See your transmitter manual

for more information about assigning a switch to a channel.

TIP: Use your radio channel monitor to conﬁ rm that the four primary channels are showing

100% travel while assigning the switch.

TIP: Use the channel monitor to make sure the switch you are assigning for SAFE Select is

active and driving a channel between 5-9 and that it is traveling 100% in each direction.

TIP: Make sure your four primary channels are not reversed if you are having trouble

assigning a SAFE Select switch.

Assigning a switch

1. Bind the aircraft to choose SAFE Select ON. This will allow the system to be assigned to

a switch.

2. Hold both transmitter sticks to the inside bottom corners and toggle the desired switch

5 times (1 toggle = full up and down) to assign that switch. The control surfaces of the

aircraft will move, indicating the switch has been selected.

Repeat the process to assign a

different switch or to deactivate the

current switch if desired.
