SECTION 24: CONTROL THROWS

We recommend initially setting up the Magic Formula 3D ARF using the Test-Flying control throws. These control throws are
suggested for initial test-flying and general sport-flying because they will allow the airplane to fly smoother and make it easier to
control. For general aerobatic flight, use the Sport-Flying control throws, but only AFTER you've become familiar with the flight
characteristics of the airplane using the Test-Flying control throws.
TEST-FLYING
Ailerons: 1-1/4" (32mm) Up & Down
Elevator: 1-1/2" (38mm) Up & Down
Rudder: 1-5/8" (40mm) Right & Left
The control throws listed are a good starting point for test-flying and aerobatics. Of course, you can adjust these control
throws to suit your particular style and tastes, but realize that the airplane will be extremely control sensitive and more
difficult to control with higher control throws.
IMPORTANT The control throws are measured from the widest point of the control surfaces.
VERY IMPORTANT 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 and 90º snap-keeper. The tubing will prevent any chance of the
clevises and snap-keepers opening during flight.
VERY IMPORTANT We do not suggest increasing the control throws beyond the recommended Sport-Flying control
throws unless you are a 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.

SECTION 25: COMPUTER RADIO SETUP AND 3D CONTROL THROWS

Although you don't have to use a computer radio to enjoy the flying qualities of the Magic Formula 3D ARF, if you're planning on
doing extreme 3D aerobatics, it is recommended. Before making any adjustments, please read and understand your radio's
setup manual.
The 3D aerobatic control throws listed below make the airplane extremely control sensitive. Use these control throws only if you
have a computer radio that you can program exponential and dual rates into. Your radio system must have the capability to turn
these control throws off during normal flight and turn them on before flying 3D maneuvers. Normal flying does not require this
amount of control throw.
3D CONTROL THROWS
Ailerons: 2-3/8" (60mm) Up & Down
Elevator: 3-7/8" (100mm) Up & Down
Rudder: As Much as Possible Right & Left
EXPONENTIAL:
Expo, as it's more commonly referred to, softens the control feel around neutral. This is especially helpful when flying an airplane
that uses a lot of control throw. Softening the neutral point makes the airplane fly more smoothly and makes it more likely that
you won't over-control.
Obviously, you may want to change the expo settings to suit your flying style, but here are some good starting points:
Ailerons: 40%
Elevator: 30%
Rudder:
READ THIS BEFORE GOING FURTHER
Because of the extreme control surface throw using the 3D control throws, you must
program exponential into the control surfaces. It will soften the control sensitivity around
neutral, making the airplane smoother and easier to control.

SPORT-FLYING
Ailerons: 1-3/4" (45mm) Up & Down
Elevator: 1-3/4" (45mm) Up & Down
Rudder: 2" (50mm) Right & Left
For 3D flying, we suggest moving the C/G back further than
the test-flying position. Move the C/G back to 5", then get a
feel for the airplane. You can continue to move it back from
there to suit your flying style, but we strongly caution you to
not move the C/G further back than 5-1/2".
