Finish The Model; Attach The Wing Panels - GREAT PLANES Jancair ES EP ARF Instruction Manual

❏
7. Sand the left side of the fuselage above the battery
pack. Clean that area with denatured alcohol. Brush a light
coat of epoxy onto the sanded area. This will provide a
smooth surface for the electronic speed control (ESC) to
adhere to. Connect the motor leads to the red and black
female bullet ends on the ESC. Use a piece of double-sided
tape to secure the ESC on/off switch to the inside of the
fuselage. Be sure that the switch or switch leads do not
interfere with the servos or pushrods.
❏
8. Repeat this procedure on the other side of the fuselage
for the receiver. Connect the ESC, rudder and elevator
servos, and a dual servo extension for the ailerons to the
receiver and secure it inside the fuselage.
❏
9. Route the antenna out of the way from the pushrods. It
can be secured on the outside of model. However, for a
clean look, we drilled a hole in the bottom of the fuselage at
the back and ran the antenna out the hole.

FINISH THE MODEL

Attach the Wing Panels

❏
1. Prepare the wing tips by sanding the inside edges of
the tips as well as scuffing up the covering at the ends of the
wing panels. Clean these surfaces with denatured alcohol.
❏
2. Mix up some 30-minute epoxy and coat a 1/4" [6 mm]-
wide strip around the inside edges of the wing tips. Fit the
wing tips to the ends of the wings with the curves pointing
up and tape them into position while the epoxy cures. Be
sure that the tips do not interfere with the movements of the
ailerons. Excess epoxy can be wiped away with alcohol.
❏
3. The preferred method of attaching the wings to the
fuselage is to glue them permanently with epoxy. The wings
have also been designed to be removable for ease of
transport if necessary. If you epoxy the wing panels to the
fuselage, thoroughly coat the carbon wing joiner tube as well
as the root ribs on the panels with epoxy, and roughen the
mating area on the fuselage with sandpaper and clean it
with alcohol. Slide the panels in place and tape them to the
fuselage while the epoxy cures.
Note: If you have glued the wing panels to the fuselage, skip
steps #4 and #5.
❏
4. To bolt the wings to the fuselage, locate the two 2-56 x
1" [25 mm] threaded rods and lightly coat one half of each
rod with epoxy. Before the epoxy cures, thread the rods into
the blind nuts in the wing panels in the location shown.
Leave 1/2" [13 mm] of each rod protruding out of the wings.
❏
5. Connect an additional servo extension to one of the
aileron servo leads and secure the connection with heat-
shrink tubing or tape. The servo extension is necessary if you
are using the Futaba 6" [150 mm] dual servo extension. Since
most micro servo models have shorter 5" [128 mm] servo
leads, they are not long enough to reach the dual servo slots.
If you purchased a standard Y-harness from another
manufacturer, you may not need an additional servo extension.
