At this stage the model should be in ready-to-ﬂ y condition

with all of the systems in place including the receiver, ESC,

and battery pack.

❏

1. Use a felt-tip pen or 1/8" [3mm]-wide tape to accurately

mark the C.G. on the top of the wing on both sides of the

fuselage. The C.G. is located 1-15/16" [49mm] back from

the leading edge of the wing at the fuselage (the seam

where the wing panels have been joined to the fuselage).

This is where your model should balance for the ﬁ rst ﬂ ights.

Later, you may wish to experiment by shifting the C.G. up to

1/8" [3mm] forward or 1/8" [3mm] back to change the ﬂ ying

characteristics. Moving the C.G. forward may improve the

smoothness and stability, but the model may be more difﬁ cult

to slow for landing. Moving the C.G. aft makes the model

more maneuverable, but could also cause it to become too

difﬁ cult to control. In any case, start at the recommended

balance point and do not at any time balance the model

outside the speciﬁ ed range.

❏

2. With all parts of the model installed (ready to ﬂ y), place

the model upside-down on a Great Planes CG Machine, or

lift it upside down at the balance point you marked.

❏

3. If the tail drops, the model is "tail heavy" and the battery

pack and/or receiver must be shifted to balance. If the nose

drops, the model is "nose heavy" and the battery pack and/or

receiver must be shifted to balance. This model is very weight

sensitive. Do not add any weight to achieve the suggested

balance point. Instead, shift the battery pack and receiver

forward or aft to alter the C.G.

PREPARE TO RUN THE FAN

This is a high performance EDF. We strongly advise

checking the EDF fan and motor mounting screws on a

regular basis.

1. Insert a wood dowel through the exhaust duct and through

the fan rotor in order to prevent the rotor from turning without

damaging it. Remove the rotor screw and washer. Extract the

rotor cone and the fan rotor from the plane.

2. Remove the motor mounting screws and washers, apply

threadlock (or a drop of CA glue) and replace. Tighten ﬁ rmly.

3. Apply threadlock on the rotor screw and reinstall the

fan assembly.

BEFORE YOU RUN THE FAN MAKE SURE THAT:

• The motor selected is one of the recommended motors.

• An appropriate ESC is being used.

• An appropriate LiPo battery is being used.

• All the screws and set screws are secured with threadlocking

compound.

• All the fan parts are properly attached to the fan and to

the airframe.

• If any part of this fan should become damaged, replace all

parts. Never attempt to repair damaged parts.
