CHECK THE C.G.
The C .G . (center of gravity) has a great effect on the way the
Corsair flies. If the C.G. is not correct the Corsair could be too
stable (reacting too slowly to control inputs) or too unstable
(reacting too quickly to control inputs) possibly causing a crash .
❏
1. With the battery disconnected, mount the propeller collet
adapter, propeller and prop hub to the motor—for now the
propeller hub needs to be only finger tight (in case the cowl
requires removal for adding ballast to the nose) .

2. Lift the model upside-down with your fingertips positioned
on the recommended C .G . location which is on the
forward
of
the two molded-in lines on the top of the wing 2-1/2” [64mm]
back from the leading edge at the fuselage .
❏
3. Adjust the location of the battery or add stick-on lead
ballast to balance the model . The above example shows 1 oz . of
stick-on lead inside the cowl .

4 . Once the C .G . has been set tighten the propeller hub using
a small screwdriver as a torque bar .
MOTOR SAFETY PRECAUTIONS –––––––
Failure to follow these safety precautions may result in severe
injury to yourself and others.
■
Seek the assistance of an experienced pilot if new to electric
motors .
■
Wear safety glasses whenever in the proximity of a spinning
propeller .
■
Do not operate the motor in an area of loose gravel or sand;
the propeller may throw such material in your face or eyes .
■
Keep spectators as well as your own face and body out of
the plane of rotation of the propeller .
■
Keep all loose clothing, long hair or any other loose objects
such as pencils or screwdrivers that may fall out pockets
away from the propeller .
MOTOR/ESC OPERATION –––––––––––––
Turning on the transmitter and operating the motor is intuitive
for most pilots who already have experience with electric motors,
but for those who may have little or no experience with electric
motors here are operating instructions for the ESC and motor
included with your Corsair:
When ready to run up the motor
first
turn on the transmitter and
make sure the throttle stick is all the way down, then connect the
