E-flite Habu 32 EDF ARF Assembly Manual
15. Use four 2mm x 8mm self-tapping screws and
a #1 Phillips screwdriver to secure the flap servo
cover to the wing.
16. Use a hobby knife with a #11 blade to trim two
1/4-inch (6mm) pieces from the silicone tubing.
Always use threadlock on metal-to-metal fasteners
to prevent them from vibrating loose.
17. Assemble the flap linkage using the two pieces
of tubing from the previous step, two 2mm nuts,
two metal clevises and the 2mm x 25mm threaded
rod. The length of the rod will be adjusted in the
following steps.
18. Use the radio system to center the flap servo.
Connect the metal clevis to the outer hole of flap
servo horn. The remaining clevis connects to the
flap control horn. Adjust the length of the linkage
so the flap is set to the mid/takeoff position of
11mm. Once the length of the linkage has been
adjusted, slide the tubing over the forks of the
clevises to keep them from accidentally opening
in flight. Use needle nose pliers to tighten the nuts
against the metal clevises.
19. Set the switch at the transmitter to the UP
flap position. Adjust the flap system values of the
transmitter for the up position until the flap is aligned
with the aileron. This will be the UP flap position.
20. Set the switch at the transmitter to the DOWN
flap position. Adjust the ATV at the transmitter for
the down position until the flap is 25mm below the
aileron. This will be the DOWN flap position.
Because there can be minor differences in control
horn and servo positions, do not connect the linkage
as described in steps 19 and 20 to the opposite
flap until you have checked the throws. Doing so
may cause the servo to bind in the UP position,
which could cause damage to the flap servo.
