Adjusting Center of Gravity (CG)

29mm

SFGs add side force in all ﬂ ight attitudes, increase

rudder authority and make possible a variety of

aerobatics.

The two SFG sets included with the Sbach 342

provide different amounts of increased rudder

control. We recommend ﬁ rst ﬂ ying the Sbach 342

without the SFGs, then with each set of SFGs to

determine what is best for your ﬂ ying style. SFGs

shown in Option 1 provide enhanced rudder

authority, while SFGs in Option 2 provide extreme

rudder authority.

Slide the SFG on to the leading edge of the wing.

Apply a few drops of foam-safe CA to stabilize

the SFGs on the wings and to prevent them from

moving in ﬂ ight.

Optional – Installation of Side Force Generators (SFGs)

The CG location is 29mm back from leading edge

of the wing at the root. This CG location has been

determined with the included 2S 180mAh 7.4V

Li-Po battery installed in the front of the battery

cavity.

Note: The oversized battery tray allows for Center

of Gravity adjustment. Start by placing the battery at

the rear edge of the battery tray with the plug facing

the rear of the aircraft. Adjust as needed by sliding

the battery back or forward. You may also turn the

battery 180 degrees, bringing the plug to the front

for connection. Wire length provides for either front-

facing or rear-facing battery connection.
