Cap off line to fuel pump and test fill system. Check
for leaks, then drain. As you drain, make sure there
are no air bubbles in the system. Residual fuel will
remain in the UAT, which is necessary for CG checks
later in the process.
Leave the plug in the fuel pump line until you are
ready to install pump. It is also suggested that you
cap the vent tube at this point to prevent fuel spills as
you invert the aircraft on your work stand.
Split Flaps
Read the flap programming guide under “preparing for
flight before proceeding. The servo arm you use will
depend upon the number of channels you will employ
for flaps.
Secure the servos in their ply mounts with screws.
Attach extension to servo and tape connection.
From the inside, mark and drill a hole approximately
40 mm from the hinge line of the split flap, aligned with
your servo arm.
Drill hole at this location from the inside, then mark
flap for control horn.
With your Dremel and cutter bit, rout the slot for the
control arm. Be very careful not to cut through the
flap, as it is very thin at this point.
Rough gluing surface on control arm, tape area
around slot, apply a very liberal amount of V-poxy into
the slot and position arm vertically.
Split flap servo. Note control arm will point at flap when fully deployed.
Mark location of control arm from inside the fuselage. See text.
