Lateral balancing will make the airplane easier to trim and will make it track straighter in the air. It is strongly
recommended.
❑
Turn the airplane upside down and tie one length of string to the propeller shaft and one length of string to the tail
wheel wire.
❑
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.
❑
Repeat the procedure a couple of more times to double-check your findings. When done properly the wing should stay
level when you lift the airplane by the string.
SECTION 14: LATERAL BALANCING THE WILD CAT 400 EP ARF
We recommend setting up the Wild Cat 400 EP ARF using the control throws listed below. These control throws are
suggested for initial test-flying because they will allow the airplane to fly smoother and make it easier to control.
TEST-FLYING
Ailerons:
1/4" Up
1/4" Down
Elevator:
3/8" Up
3/8" Down
Rudder:
3/8" Right
3/8" Left
☞
Measure the control surface throw from the widest point of the control surface.

We do not suggest increasing the control throws beyond the recommended aerobatic-flying settings
unless you are a very proficient flyer. Higher control throws will cause the airplane to be extremely control-sensitive and
result in a possible crash if you are not careful.
Once you're familiar with the flight characteristics of the airplane, you might want to increase the control throws to the
aerobatic-flying settings listed below. These control throws will make the airplane more responsive and allow you to do
most aerobatics with ease.
