C/G AND BALANCING
BALANCE POINT (C/G):
l
IMPORTANT It is critical that your airplane be balanced correctly. Incorrectly balancing your airplane can cause your airplane
to lose control and crash!
+
Once you have own and become familiar with the ight characteristics of the airplane, the C/G can be moved fore or aft to change
the ight performance. Moving the C/G back will cause the airplane to be more responsive, but less stable. Moving the C/G forward will
cause the airplane to be more stable, but less responsive.
FOR 3D FLYING YOU CAN MOvE THE BALANCE POINT BACk IN SMALL INCREMENTS UNTIL YOU'RE SATISFIED WITH THE RESULT.
BE AWARE THAT MOvING THE BALANCE POINT BACk TOO FAR CAN RESULT IN AN UNCONTROLLABLE AIRPLANE!
IMPORTANT Balance the airplane with the fuel tank empty. If you have installed an electric power system, balance the airplane
with the battery installed.
Lateral balancing will make the airplane's controls easier to trim and will make the airplane track straighter in the air. It is strongly
recommended.
q Turn the airplane and tie one length of string to the propeller shaft and loop a second length of string around the
tail U-Shaped bend in the tail skid.
q With someone helping you, carefully lift the airplane up by the two pieces of string. Watch how the wing reacts. If one side of
the wing drops, that side is heavier than the other. To correct this condition, stick a small piece of self-adhesive lead weight to the
bottom of the lighter wing half (the one that doesn't drop). For best mechanical advantage, place the weight as close to the wing tip
as possible, but make sure to apply the lead weight to a solid portion of the wing structure so that it can't rip off during ight.
q Repeat the procedure a couple of more times to double-check your ndings. When done properly the wing should stay level when
you lift the airplane.
LATERAL BALANCING
AIRCRAFT SETUP INFORMATION
We recommend initially setting up the airplane using the Test Flying/Sport Flying control throws. These control throws are suggested
for initial test ying because they will allow the airplane to y smoother and make it easier to control. These control throws are also
good for general sport ying. For 3D ying, increase the control throws to your own desired amount.
CONTROL THROWS
Rudder: 3-1/8" (80mm) / 4-1/4" (110mm) Right and Left
TEST FLYING / SPORT FLYING
Rudder: As Much As Possible Right and Left
3D FLYING
THE CONTROL THROWS ARE MEASURED FROM THE WIDEST POINT OF THE CONTROL SURFACES
vERY IMPORTANT After you are nished adjusting the pushrods and control throws, we strongly suggest installing 3/8" (10mm)
long pieces of fuel tubing over the clevises and snap-keepers to lock them into place.
vERY IMPORTANT
We do not suggest increasing the control throws beyond the recommended Sport Flying control throws
unless you are a procient yer. Higher control throws will cause the airplane to be extremely control-sensitive and result in a
possible crash if you are not careful.
