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 willingto help you with your first few flights.
Although this is an ARF (Almost-Ready-to-Fly) kit, 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.

Balance Point

The Center of Gravity (C/G or Balance Point) is 2

95" 

(75mm) 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.

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.
