Dual Rates and Expos

To obtain the best ﬂ ight performance, we

recommend using a DSM2

/DSMX

transmitter

capable of Dual Rates. Before binding, ensure that

you are starting with a blank acro model in your

transmitter. Set wing type and servo reversing to

normal.

The suggested settings shown here are the

recommended starting settings. Adjust according to

the individual preferences after the initial ﬂ ight.

NOTICE: Do not set your transmitter travel adjust

over 100%. If the TRAVEL ADJUST is set over

100%, it will not result in more control movement, it

will overdrive the servo and cause damage.

It is normal for linear servos to make signiﬁ cant

noise. The noise is not an indication of a faulty

servo.

Tip: For the ﬁ rst ﬂ ight, ﬂ y the model in low rate.

The illustration shows linkage positions chosen for

the best aerobatic response. Linkage connections

on the control horns directly affect aircraft response.

Before your ﬁ rst ﬂ ight make sure the aircraft’s

control surfaces are centered.

1. Power on the transmitter and then the aircraft.

2. Set all transmitter trims and sub-trims to zero.

3. Check the control surfaces to make sure they

are centered.

4. If centering is required, use a pair of pliers to

carefully bend the metal linkage

(see illustration).

In ﬂ ight trimming may be required

During your ﬁ rst ﬂ ight, the aircraft should ﬂ y

straight and level. Use your transmitter trims to

ﬁ ne-tune the aircraft’s ﬂ ight path until it has been

corrected. Any transmitter trim that requires 4

or more clicks of trim (per channel), should be

mechanically centered. Note the control surface’s

postion and return the transmitter trim to zero.

Adjust the linkages mechanically so that the control

surfaces are in the ﬂ ight trimmed position.

Make the U-shape narrower to make the

connector shorter. Make the U-shape wider to

make the linkage longer.
