TOP OF WING

4-1/8" [105 mm]

 1. If you will be using a Great Planes C.G. Machine

 

to check the balance point, set the rulers to 4-1/8" 
[105mm]. If 

not

 using a Great Planes C.G. Machine, 

and if you haven’t already done so, use a straightedge 
and a fi ne-point felt-tip pen to mark the balance point 
on the top of the wing panels 4-1/8" [105mm] back 
from the leading edges and place 1/16" to 1/8" [1.5 to 
3mm] strips of tape over the lines so you will be able 
to feel the balance point with your fi ngers when lifting 
the model upside-down.

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 3/8" [10mm] forward or 3/8" [10mm] 
back to change the fl ying characteristics. Moving 
the C.G. forward may improve the smoothness and 
stability, but the model may then require more speed 
for takeoff and make it 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. If you haven’t done so already, mount the wing 

to the fuselage. If you have retractable landing gear, 
retract the gear into the wing. With all parts of the 
model installed, the model ready to fl y and an empty 

fuel tank, place the model on a CG Machine or lift it 
with your fi ngers on the balance points marked by the 
thin strips of tape.

 3. If the tail drops, the model is “tail heavy” and 

weight must be added to the nose to balance. If the 
nose drops, the model is “nose heavy” and weight 
must be added to the tail to balance. If any additional 
weight is required to get the model to balance, use 
Great Planes “stick-on” lead (GPMQ4485). The best 
place to add stick-on nose weight is to the fi rewall and 
the best place to add tail weight is inside the tail cover. 
Begin by placing incrementally increasing amounts of 
weight on the fuselage over the location where it will 
be permanently attached inside until you can get it to 
balance. Once you have determined the amount of 
weight required (or the battery positioning if possible), 
it can be permanently attached. 

Note:

 Do not rely 

upon the adhesive on the back of the lead weight to 
permanently hold it in place. Over time, the adhesive 
may weaken causing the weight to fall off. Use #2 sheet 
metal screws, RTV silicone or epoxy to permanently 
hold the weight in place. 

 4. 

IMPORTANT:

 Once you’ve added any additional 

weight, recheck the C.G.

BALANCE THE MODEL LATERALLY

 1. With the wing level, lift the model under the tail 

and by the propeller shaft. Do this several times.

 2. If one wing always drops when you lift the model, 

it means that side is heavy. Balance the airplane by 
adding weight to the other wing tip.

 An airplane that 

has been laterally balanced will track better in fl ight 
and maintain its heading better during maneuvers 
when the plane is climbing.

PREFLIGHT

CHECK THE CONTROL DIRECTIONS

 1. Turn on the transmitter and receiver and center 

the trims. If necessary, remove the servo arms from 
the servos and reposition them so they are centered. 
Reinstall the screws that hold on the servo arms.

 2. With the transmitter and receiver still on, check 

all the control surfaces to see if they are centered. If 
necessary, adjust the clevises on the pushrods to 
center the control surfaces.

 3. Make certain that the control surfaces and the 

carburetor respond in the correct direction as shown in 
the diagram. If any of the controls respond in the wrong 
direction, use the servo reversing in the transmitter to 
reverse the servos connected to those controls. Be 
certain the control surfaces have remained centered. 

Adjust if necessary.

SET THE  CONTROL THROWS

To ensure a successful fi rst fl ight, set up your Corsair 
.60 ARF according to the control throws provided. 
The throws have been determined through record-
keeping and fl ight testing, allowing the model to 
perform in the manner in which it was intended. If, 
after you have become accustomed to the way the 
Corsair fl ies, you would like to change the throws 
to suit your taste, that is fi ne. However, too much 
control throw could make the model too responsive 
and diffi cult to control, so remember, “more is not 
always better.”
