Assembly instructions
Thread the crimp sleeve onto the cable where it exits the fuselage fairing,
then fit the cable through the ring-screw.
Now slip the cable through the same crimp sleeve again, as shown in
Fig. 12 , and squeeze the sleeve firmly together using a pair of pliers.
Repeat the process on the other side, checking that the cable is properly
taut.
This guarantees an accurate rudder linkage.
6. Fitting the wing
Slide the joiner tube into one wing panel, then through the fuselage. Route
the aileron servo lead up and out of the way before sliding the second
wing onto the joiner. The wing is secured against the fuselage using the
wing retainer, which is fitted through the wings and into the M-Frame
from above
Fig. 13 .
7. Fitting the propeller and spinner
Check that the motor retaining screws are tight while you still have good
access to them. This is normally part of pre-flight checking, but it is no
longer possible once the propeller and spinner are in place.
Fit the propeller on the motor shaft as shown in Fig. 14 . We recommend
that you use our propeller balancer # 332355 to check the dynamic
balance of the propeller before installing it. Be sure to tighten the
propeller nut firmly. The spinner is simply a push-fit on the front of the
propeller driver. Rotate the propeller by hand, and check the gap between
the fuselage and the back of the spinner: the spinner must not foul the
fuselage, and must rotate absolutely true. For safety reasons please
disconnect the battery before you do this!
8. Installing and retaining the battery, Centre of Gravity
Mount the flight battery on the battery support plate using the hook-and-
loop strap supplied, and adjust its position until the model balances at the
108 mm point with the canopy fitted and closed; this point is measured
from the wing root leading edge
Fig. 15 . The battery plate fits in the
fuselage with the lug at the front, which engages in a slot. Now secure
the plate by fitting the plastic M4 knurled screw
Fig. 16 ; you may wish
to shorten the knurled screw with a modelling knife. An alternative to the
plastic screw is an M4 cap-head screw, which can then be fitted easily
using a magnetic allen key.
9. Settings of the control surfaces
Set up the control surface travels as stated below. They are only a guide,
and you may wish to alter them to suit your personal preference:
Normal aerobatics („pattem“ flying), outer holes at the control
surface horns:
Elevator Up approx. +40mm; 50% Expo
Elevator Down approx. -40mm; 50% Expo
Ailerons Up approx. +50mm; 50% Expo
Ailerons Down approx. -50mm; 50% Expo
Rudder Right approx. +80mm; 50% Expo
Rudder Left approx. +80mm; 50% Expo
3D and XA Style
Elevator Up approx. +120mm; 65% Expo
Elevator Down approx. -120mm; 65% Expo
Ailerons Up approx. +70mm; 65% Expo
Ailerons Down approx. -70mm; 65% Expo
Rudder Right approx. +120mm; 65% Expo
Rudder Left approx. +120mm; 65% Expo
!CAUTION! ;
the RR version of the Extra is supplied set up for all-round
flying. The model can be fine-tuned to suit extreme 3D aerobatics and
the XA flying style using the following procedure:
- To achieve larger control surface travels you must modify the aileron
and elevator horns. This is the method: shorten the horns using a pair
of pincers or a mini cut-off disc, and re-connect the pushrods to the
innermost holes.
- To achieve an even higher roll rate and improve stability in the hover,
it is a good idea to seal the control surface hinge lines using adhesive
tape (aileron and elevator).
This is accomplished by moving the control surface to the ‘full-travel’
position, and pressing a strip of tape into the gap from the underside.
Before every flight check that the battery, the wing and the tail
surfaces are securely fixed. Check that all control surfaces
are working properly!
