EG recommends an initial CG setting of 7.0 – 8.0 inches behind the
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.
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 100cc 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
FINAL ASSEMBLY AND PRE-FLIGHT INSPECTIONS:
1. Before arriving at your flying field, be sure all your batteries are properly charged and all radio
systems are in proper working order.
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 are recommended. Once you
have the wings fully seated in the fuselage tighten the wing bolts inside the fuselage.
3. Fill your fuel tank making sure your vent line is not plugged or capped. With the canopy off, this is a
good time to check for any fuel leaks.
4. Position the canopy in place and tighten the canopy screws. Be sure to use the supplied rubber
washers under the screw heads.
5. If you have removed your horizontal stabilizers, intall them once again and check all bolts and
connections.
6. Check all control surfaces for secure hinges by performed a slight tug on the control surfaces and
observing if there is any give in the hinges. Check all control rods, ball links, servo screws, etc. for
proper operation and installation.
7. Check your batteries and perform a proper range check once again with the engine off and running. Be
sure all surfaces are moving in the correct direction and the proper amount for your flying setup.
8. You are now ready for your maiden flight! Good luck and enjoy your new aircraft! If you have any
