Balancing and Pre-Flight Checks
Most state of the art aerobatic aircraft allow for a wide margin for balancing depending on what
level of precision or freestyle flying the pilot prefers. To perform properly without being too pitch
sensitive, you must not go too aft on the CG. GoldWing RC recommends an initial CG setting of
130-152mm (5.1-6.0 inches) 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
engines and radio gear will dictate how you should install each. The batteries can easily be
located pretty much anywhere in the fuselage. For those using a heavy engine, servo cutouts are
provided in the rear of the fuselage for the rudder servos. These options should allow you to
balance the model without adding any weight.
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.
Recommended control surface deflections:
Low Rate High Rate
Elevator 15 degrees 45-50 degrees
Rudder 25 degrees 40 - 45 degrees
Ailerons 25 degrees 35-40 degrees
Use exponential on the dual rates at levels that suit your flying style.
If you find that you require tail weight and cannot move parts around the aircraft a rear hatch has
been added. Glue in the inner ring, once the covering has been removed. Then screw on the
supplied cover.
