MotorThrust
To ensuregreatflight performance and to be able
to trim yourairplane properly, it
is critical thatyou
adjustthe motorthrustas described.
We suggest
thatyou add 2 degrees
of down-thrustand 1
degrees
of right-thrust. Thiscan be achieved by
addingawasher
or two behind thetop and right
side
of the motor(between the motorand the
firewall}. When setproperly, the trim forthe
elevatorand the ruddershould be neutral. Fine-
tune the down-thrustand right-thrust until this trim
is achieved.

Balance Point
The CenterofGravity(C/G or Balance Point)
is 80mm( 3. 15")
from the leading edge ofthe wing,measured at the centerofthe
wing.
WARNING Fortestflying and general sportflying, we suggestyou
balancethe airplane at the C/G recommended above.For
3D
flying, you maywantto 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
