The Main Airbrakes; Diagram 8; Diagram 9; Trimming Your Clik Evo - RC Factory Clik Evo Building Instructions

The main airbrakes: prepare the holding carbon rods (2 pairs of 0.8x100
and 2 pairs of 0.8x140) and sharpen one end of each. Pierce the rods
„ "
into the SFGs (at the dotted line locations) and CA glue. Make sure
that the 100 mm rods are glued into SFGs at the very tip of the wing.
Install the airbrakes at the end of the rods (use CA).

Diagram 8:

Install the motor. Use your preferred method, the makers of the motors
often include a glassfiber firewall.
We prefer a method where the thrust angle can be adjusted when trimming
your airplane.

Diagram 9:

Install your servos and linkages (for rudder and elevator we prefer to
–
use the pull pull strings system, for ailerons the 1 x 160mm control
rods). To achieve the correct geometry and be able to change the aileron
differential if necessary, we use the aileron extension servo horn
(part 5 on the plywood frame).

Trimming your Clik Evo

We expect that you know how to connect the receiver to the ESC and to the
servos, the ESC
to the motor etc. If not, please refer to the respective instructions or
better ask some more
experienced friend.
For first flights, your C of G should be in the position of the strut
°
anchor. Set 35 deflections
on all controls. Check all systems and go fly. To trim the plane
correctly, you have to be
indoors or it has to be absolutely calm outdoors. First, trim all
controls coarsely to make the
plane appear to fly straight. You should need about the same amount of
elevator for both
inverted and normal flight. If you have enough clearance, you may try
vertical dive to trim the
neutral elevator.
Your aileron trim should be the same in normal flight and inverted. If it
is not, you may have
a lateral balance issue. Try to move the battery pack sideways (say to
the opposite side of the
fuselage), if you can, to fix this problem.
After this, you should play with the thrust line to setup for clean and
effortless hover without
" "
any tendency to pull out to any side. This may take a while and require
quite a few tests.
If your model needs different rudder trim for normal and inverted
flight, this may be also a thrust angle issue.
" "
Next thing, the C of G. We prefer the plane to fly almost hands off ,
just the slightest bit of
elevator needed for level flight. Move the C of G vertically (by moving
the battery pack) to
