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.
