Control Centering

In the event of an accident or before your first flight, check to

make sure the flight control surfaces are centered. It is much

better to do this mechanically due to the mechanical limits of

linear servos.

1. Make sure the transmitter trims are centered, and if your

transmitter has them, sub-trims are set to 0.

2. Check to see if any flight control surfaces are not centered.
3. If the surface is not centered, use a pair of pliers and carefully

lengthen or shorten the pushrod by bending the U-shape in the

pushrod.

Control Throws, Expo, and CG

While the SU-26

can be flown with any full size DSM2

transmitter such as the DX5e, it is preferable to use a

transmitter with an EXPO function in addition to Dual Rates for a

more precise control feel. The Sukhoi SU-26

is factory set to

standard control throws. We recommended you follow the standard

control setup chart and the first flights be done on low rates.

Note: If using a non-computer transmitter such as the DX5e,

the low rates are already preset for you. Be sure the

rate switch is set to the Lo position for the first flights.

If using a programmable DSM2 transmitter, set the rates

and Expo settings per the Standard Control Setup chart,

and again be sure the rate switches are set to the Lo

setting for the first flights.

The Dual Rate and EXPO values on the charts are suggested

starting points that are typical for this type of model, however

these values are dependant on pilot preference and should be

adjusted to personal taste.

If you want 3D capable elevator throw and are using a

programmable transmitter with EXPO feature, move the elevator

pushrod to the inner hole in the control horn and set the Dual Rate

and EXPO values in your transmitter per the 3D Control Setup

chart. Use the Lo rate setting for normal flying and flip to 3D rates

for wild 3D flying.

Note: DO NOT SET YOUR TRANSMITTER ATV OVER

100%. If the ATV is set over 100% it will not result

in more control movement, and it will overdrive

the servo and cause damage.

CG Range: 35–37mm back from the leading edge where the wing

meets the fuselage.

Note: After initial flights, the CG can be adjusted to your

preferences by moving the battery forward or backward.

Receiver Control Unit Description, Arming

and Motor Control Test

The receiver installed on your Sukhoi SU-26

is a lightweight

combination of main motor electronic speed control, servos and

Spektrum DSM2 compatible receiver. The receiver unit is also

equipped with a status indicator LED.
Before each flight ALWAYS turn the transmitter on before

connecting the flight battery to the receiver unit. Never connect the

flight battery to the receiver unit before powering the transmitter

on. After each flight, always disconnect the flight battery from the

receiver unit before powering the transmitter off.
