 9. Use a few dabs of clear RTV silicone, R/C 56 canopy 

glue or double-sided adhesive tape to hold the canopy to the 
top of the wing or to the doubler. 

Note:

 Non-permanent glue 

is recommended to allow for easy removal of the canopy in 
the future.

GET THE MODEL READY TO FLY

Check the Control Throws

If the pushrods were connected to the servo arms as 
previously illustrated, then the control throws should already 
be correct, or very nearly correct. However, it is still a good 
idea to check the throws since they have such a great effect 
on how the model fl ies.

❏

 1. 

Make sure the throttle stick is all the way down

 so 

you do not accidentally arm or start the motor. Turn on your 
transmitter and connect a battery to the ESC.

❏

 2. Make sure the ailerons, elevator and rudder are centered. 

If necessary, adjust the pushrods in the screw-lock connectors 
to center the controls and re-tighten the screws in the 
screw-locks.

Measure the elevator throw fi rst…

❏

 3. Hold a ruler to the trailing edge of the elevator. Note the 

measurement. 

❏

 4. Use the transmitter to move the elevator to full “up” and 

note how far the elevator moved. This is the “up” elevator throw.

On the servo, move the pushrod 

out

 to increase throw,

or 

in

 to decrease throw.

On the control surface,
move the pushrod 

in

 to increase throw,

or 

out

 to decrease throw.

More throw

Less throw

❏

 5. Make sure the up elevator throw you measured is the 

same as the throw specifi ed on the following page. Measure 
the down elevator throw and the rudder and aileron throw the 
same way for both the high and low rates. If the throws on your 
plane are within 1/8" [3mm] of the specifi ed throws, go ahead 
and fi ne-tune the throws using the End Point adjustments 
in your transmitter. If the throws are too far off, change the 
throws by relocating the pushrods on the servo arms and/or 
control horns on the surfaces. Moving the pushrods inward 
on the servos or outward on the control surfaces will provide 
less throw and moving the pushrods outward on the servos 
or inward on the control surfaces will provide more throw.
