4.Gather your aileron and elevator servos, all servo arms and hardware so we can
install those items. I will discuss the elevator installation, but the ailerons install
very similarly. I found it is easier to mount the servos without the servo arm
attached, so install your elevator servo into the slot and secure with the
manufacturers recommended screws. You will need to retrieve the servo wire back
thru the hole in front of the servo, hemostats are very handy for this. The outer
aileron servo will require a 36” extension.See figure 6 for our installation.

5. Now that the elevator and aileron servos are installed, lets hook up the pushrods
and ball links. Locate the pushrods/ball links/3mm bolts/nylon insert nuts/washers
from the respective hardware bags.
This procedure will serve as the direction for all servo to control horn linkages on
this plane. First, electronically center your servos. Now thread the ball links onto
the pushrod, note that one will thread on with right hand threads and the other has
left hand threads. It does not matter which ball link you use, just thread them on
according to the thread direction. Make sure they are on at least 10 complete turns,
however I noted that there were only a few threads showing once I centered
everything during my setup. Now put the ball link in between the control horns and
insert the 3mm bolt with washer thru the control horn and ball link. Now install a
washer, blue thread lock and the nylon insert nut. Now install the ball link into the
servo arm using the same sequence as the control horn. Figure 8 shows a
completed elevator setup.
