SECTION 20: CONTROL THROWS
We recommend setting up the F-20 Tigershark 40 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.

The control throws are measured from the widest point of the control surfaces.

After you are finished adjusting the pushrods and control throws, we strongly suggest cutting
1/4" lengths of the clear tubing provided and sliding one piece over each clevis. The tubing will prevent the clevises from
popping open during flight.
Once you're familiar with the flight characteristics of the airplane, you might want to increase the control throws to the
sport-flying settings listed below. These control throws will make the airplane more responsive and allow you to do most
aerobatics with ease.
Ailerons: 3/16" Up 3/16" Down
Elevator: 3/16" Up 3/16" Down
Rudder: 1" Right 1" Left

We do not suggest increasing the control throws beyond the recommended sport-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.

Elevator: 5/16" Up 5/16" Down
Rudder: 1-3/4" Right 1-3/4" Left
WARNING ABOUT THROTTLE MANAGEMENT
It is very important that you understand throttle management. In a nutshell, this means no full throttle dives.
Full throttle dives should be avoided so as not to cause control surface flutter and/or airframe failure. When the
nose of the airplane drops, decrease the throttle.
SECTION 21: PREFLIGHT CHECK & SAFETY
●
Completely charge the transmitter and receiver batteries before your first day of flying.
●
Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded. This
should include all of the control surface hinges as well.
●
Double-check that you've installed and tightened all of the servo horn retaining screws.
●
Double-check that the receiver and battery are properly secured in the fuselage. There's nothing worse than the
battery pack coming loose during flight.
