Please Note: After removing kit from shipping
box, lay each piece flat on a hard surface, this will
allow the airframe to straighten out if lightly bent
from shipping. Do not worry since EPP is very
pliable and can be bent back if out of shape.
Double check that you have all the above
pictured items. If any of the airframe or hardware
items are missing, contact TA Horizons before

to the pre laser hole in all arms and horns.
52. Screw all quick links to the pre laser hole in all arms and horns, do
not tighten them too much, make sure they can rotate freely.
53. Glue the aileron horns shown in the image in the precut control
horn slot using HV CA. Make sure it sits right to the bottom of EPP
Surface.

CONTROL THROWS
In order to achieve the control throws
as described for “Extreme & 3D”, it is
imperative that the control surface,
linkages, rod ends, etc, all move
freely over the entire range, including
range end points.
Failure to do so will result in damage
to either the servos or mechanical
components
