6. 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.
BALANCING and PRE-FLIGHT
1. 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 141-164mm(5.5-6.5 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.
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.
