Seek Assistance
If you are new to R/C we suggest you find an experienced pilot to check out your aircraft and help you with the first
few flights. This will help prevent damage to your model and will speed up the learning process and making your
R/C experience all the more enjoyable. You can contact local R/C clubs or your dealer to obtain the names of
experienced R/C pilots who would be willing to help you with your first few flights.
Although this is an it does have some construction features that can be challenging
to the less experienced modeler. If you encounter difficulty in any construction sequence, please feel free to
contact one of our technicians, we stand ready to provide any assistance we can. Contact us at:

ARF (Almost-Ready-to-Fly) kit,
The Center of Gravity (C/G or Balance Point) is 3.9” (98mm)
from the leading edge of the wing, measured at the center of
the wing.
WARNING For test flying and general sport flying, we
suggest you balance the airplane at the C/G
recommended above. For 3D flying, you may want to
experiment moving the C/G back in small increments until
you're satisfied with the result.

Ailerons: (82mm)3.23" Up and Down
Elevator: (90mm)3.54" Up and Down
R udder: (117mm)4.60" Right and Left
The control throws are measured from the widest
point of the control surfaces

Exponential softens the response of the control surfaces
around neutral stick. This makes the airplane easier to
control while using such large control throws. The
Exponential values shown are given as a percent. Please
note that different brands of radio control systems may
call for + or - Expo. Please check your transmitter's
owners manual for more info.

Motor Thrust
To ensure great flight performance and to
be able to trim your airplane properly, it is
critical that you adjust the motor thrust as
described. We suggest that you add 2
degrees of down-thrust and 1 degrees of
right-thrust. This can be achieved by adding
a washer or two behind the top and right
side of the motor (between the motor and
the firewall). When set properly, the trim for
the elevator and the rudder should be
neutral. Fine-tune the down-thrust and
right-thrust until this trim is achieved.
