S140131 Mentor-G V3
7.
Test fit the
horizontal stabilizer
, then use a soldering iron or wood-burning tool to remove the Mylar
covering that will be ‘buried’ inside its mounting- slot at the rear of the fuselage.
8.
Using 5-minute
epoxy, secure the
horizontal stab. into
its slot at the rear of
the fuselage; before
this epoxy thickens,
make sure that the
horizontal stabilizer
is aligned
at right
angles to the fuselage by measuring the distance between the outside rear
bolts on the landing gear and the outside end of each half of the horizontal
stabilizer – and adjust the horizontal stabilizer so this distance is the same
on both sides of the fuselage.
9.
If you will use 1 elevator servo, insert
the prebent elevator connector into its
precut openings each half of the ele-
vator as shown at the right. Test fit
the elevator to the horizontal
stabilizer. Use epoxy on both ends of
the prebent connector to both halves of the elevator. If you will use two ele-
vator servos, do not connect the two halves of the elevator. Secure the ele-
vator to the horizontal stabilizer by applying thin CA adhesive to each of the elevator’s CA hinges.
NOTE: a) For hi-stress aerobatic flying the Mentor-G’s tail section may be reinforced by adding stranded
metal wire (not included) to surround the entire empennage. Begin by attaching the wire at the bottom of
the fuselage, pass the wire through one end of the horizontal stabilizer, then through the top of the
vertical stabilizer, through the other end of the horizontal stabilizer, then draw it tight and attach it to the
bottom of the fuselage. b) If you convert the landing gear to a tricycle configuration, you may use scrap
plywood to reinforce the more-aft mounting position of the main landing gear on the bottom of the
fuselage and you may use a spare opening in the servo tray for your nose-wheel-steering servo.
10.
Position the pushrod-openings in the control horns directly over the hinge lines and
drill holes
in the
rudder and elevator for the control horn mounting bolts. Attach one control horn to the rudder and one
control horn to the elevator. (Note: If you setup the elevator to be driven by two servos, remove the
covering material from the precut servo opening in the top of the fuselage directly in front of the rudder,
and mount your rudder servo in this ‘extra’ servo-mounting opening.)
11.
Connect a
12-inch servo-wire extension
to each of your rudder and elevator servos.
(Note: To ensure the security of your servo extension connections, we recommend you
install an optional “servo extension safety clip” at each servo wire/extension junction.)
12.
Guide the servo extensions through the rudder and elevator servo openings and into the fuselage, then secure
the ends of the extensions inside the fuselage on the radio receiver’s tray with a piece of masking tape.
13.
Using your servos’ hardware, mount your
elevator and rudder servos
in their openings. Using the
preformed Z-bends and the supplied clevises, attach the
pushrods
as shown. (NOTE: The provided
control horns give the ailerons, rudder and elevator a wide range of adjustability to accommodate the
builder’s preferences. We recommend beginner pilots start with the pushrods connected to the outer-
most holes; more advanced pilots may adjust pushrod positions for additioal throw, if desired.)
