7.5 Check all radio programming and control surface operations thouroughly before your initial
flight. Check your radio range according to the radio manufacturer’s instructions both with the
engine off and running.
8 Balancing and Pre-Flight
Most state of the art aerobatic aircraft allow for a wide margin for balancing depending on what
level of precision or freestyle the pilot prefers. To perform properly without being too pitch
sensitive, you must not go too aft on the CG. We recommends an initial CG setting of
101-
123mm(4.0-4.8inches)
behind the leading edge of the wing at the root. More experienced
pilots may want to set the CG further aft for more 3D capability. Varying weights of motor and
radio gear will dictate how you should install each.
Note: The best way to check your balance is to trim for level flight at about 1/2 to 3/4 throttle
and then roll inverted. The aircraft should maintain level flight with very little to no down
elevator input. If the aircraft climbs when inverted then you’ve probably got your CG too far aft.
If the nose drops more than slightly, then you are most likely nose heavy.

9. Final Assembly and Pre-Flight Inspections
9.1 Before arriving at your flying field, be sure all your batteries are properly charged and all
radio systems are in proper working order.
9.2 Install the wings onto the fuselage being careful to align the wing tube with the wings and
not force it. The wing tube may be initially tight but will loosen some with use. Guide your
servo wires into the fuselage openings and connect to the proper aileron channels. Servo clips
