Important:
the two pegs must be installed exactly in line with each other; please
work carefully at this stage.
Screw the two quick-release couplings into the aluminium threaded sleeve.
Temporarily assemble the model in order to check the fit of the retainer system: when
the length of the system is correct, dismantle it again and unscrew the quick-release
couplings by about 5 mm so that you can apply thread-lock fluid to them. Re-
assemble the whole system, rig the model as previously, and leave it assembled until
the thread-lock fluid has cured. It is important to ensure that both wing panels rest
snugly against the fuselage, and that both quick-release couplings are fully engaged.
The quick-release couplings are disengaged by pushing back the union ring using a
screwdriver; the wing panels can then be pulled away from the fuselage. The wing
retainer system also acts as a brace for the fuselage, prevent compression damage
in abrupt landings.
Assembling the DISCUS 2 cT
Connect the appropriate extension leads to the receiver sockets, and route them to
the openings in the wing root fairings. Use retainer plates and cable-ties to fix the
extension leads to the fuselage sides. Fit the wing joiner through the fuselage and
slide the wings onto it, engaging the incidence pegs in the holes in the root fairings.
Connect the aileron and airbrake servos to the extension leads which are now
permanently plugged into the receiver.
Push the wing panels inward so that the retainer system engages and holds them
against the fuselage sides. Fit the canopy on the fuselage and engage the canopy
latch at the rear. Attach the tailplane to the fin using the two M4 socket-head cap
screws supplied. Connect the clevis to the elevator horn.
Both winglets must be sticked into the wings by using two pieces of brass tube, take
adhesive film for fastening.
The 2 pieces of brass tube can be pasted into the winglets by using Epoxyd glue.
Balancing the DISCUS 2 cT
Assemble the model completely, ready to fly, and support it at a point about 80 - 89
mm aft of the wing root leading edge on both sides of the fuselage. The model should
now balance level, ideally with the nose inclined slightly down. Make any adjustments
required by shifting the receiver battery, and / or install lead ballast in the nose; the
latter must be fixed to the fuselage permanently and immovably. Before flying the
model for the first time, check that all the control surfaces are exactly at centre
(neutral position) when the transmitter sticks and trims are at centre.
Control surface travels:
Ailerons
22 mm up
2 mm down
Elevator
6 mm up
6 mm down
Rudder
35 mm right
35 mm left
We suggest setting about 4 mm up-elevator trim to counteract the pitch trim change
when the airbrakes are deployed.
The stated travels are only a recommended starting point; you may well wish to
adjust them to suit your personal preference.
