Tape the rudder in the neutral position and look from the rear to verify that the trailing edge of the rudder is perfectly
vertical. If it twists to one side, carefully counter twist it in the other direction and apply heat where it wrinkles using an
iron as you did with the ailerons and elevator. Continue until the trailing edge of the rudder forms a perfectly centered
vertical line.
Tail Landing Gear (LG)
Align the tail LG against the rudder and use the tip of the wire to mark the position of the hole to drill for the wire to fit
in. Drill a hole in the marked position using a 1.0mm drill bit. With the LG in place verify its alignment with the rudder
and if needed correct it by bending the strut with pliers before glued in.
Make some indentations in the surface of the LG wire using a file/Dremel tool. The indentations provide better surface for
the glue to bond.
Apply 30 minute epoxy (not CA) over the wire and drilled hole and install the LG. Apply another thick layer of epoxy over
the LG wire. You may lay a small piece of fiberglass cloth or scotch tape over for additional reinforcement. Leave the
assembly aside until the epoxy sets. Note: if the wheel doesn’t spin freely, wobble it a bit until it spins freely.
Elevator & Rudder servos
The tail servos require a pair of 410mm/16" extension leads (if NXT70-HV is used). We recommend extending the leads
using a good quality lightweight servo extension to save on weight, avoid RF noises and voltage drop (PA Item Code AC-
1713 is a German made low resistance flexible Extension Lead and is included in the iPAs Pro package). Cut the servo
lead close to the servo case. Expose each cable end, then solder each to the extension lead according to the colors.
Insulate the cables with a shrinking tube over each of the soldered cables (fit them on before soldering the wires).
