Control Direction Test

You should bind your aircraft and transmitter before 
doing these tests. Move the controls on the trans-
mitter to make sure the aircraft control surfaces 
move correctly and in the proper direction.

Make sure the tail linkages move freely and that 
paint or decals are not adhered to them.

Side Force Generators (SFGs) Installation

Side Force Generators add side force in all fl ight 
attitudes, increase rudder authority and make a 
variety of aerobatics possible.

1.   Slide each SFG in the respective channel on 

the leading edge of the wing.

NOTICE:

 Install the SFGs vertically on the wing. 

Failure to install the SFGs at a 90º angle may result 
in incorrect fl ight performance.

2.   Apply a few drops of

 foam-safe

 CA (cyano-

acrylate adhesive) to stabilize an SFG on the 
wing and to prevent it from moving in flight.

Landing Gear Installation

1.   Push together the legs of the main gear strut.

2.   Insert the top of the strut into the slot in the 

bottom of the fuselage so with the wheels 
raked foreward as shown.

When needed, disassemble in reverse order.
