The flight battery should be fitted in the battery compartment from the servo end, as
shown in the photo, and slid forward as far as it will go. Push a block of foam behind
the battery to prevent it shifting, and secure it with a rubber band.
Assembling the model
Connect the rudder servo to the extension lead, and secure the connection by
wrapping it with adhesive tape; alternatively use a retainer clip, Order No. 3503. Fit
the hardwood tongue on the tailplane into the slot in the fuselage former, and fit the
M4 plastic retaining screw at the rear.
Fit the aluminium joiner tube through the fuselage and slide both wing panels onto it;
each panel is secured using two M4 plastic screws. Don’t over-tighten the screws;
tighten them just to the point where the wings are held securely against the fuselage.
Slide the flight battery into its compartment, and secure it as described earlier.
Place the fuselage hatch in the recess, and engage the two hardwood lugs in the
slots in the former. The hatch can now be secured by fitting two M4 plastic screws at
the rear. Tighten the screws just to the point where the hatch is firmly fixed to the
fuselage.
The final task is to apply the decals to the finished model. Cut out the individual
emblems from the decal sheet, leaving a narrow excess of clear material around
each one. Apply the decals to the model in the arrangement shown in the kit box
illustration and the title picture.
Balancing the B-25 MITCHELL
Install all the airborne equipment in the model, assemble it fully, ready for flight, and
support it on both sides of the fuselage at a point about 80 - 85 mm aft of the wing
root leading edge. When the CG position is correct, the model will balance level, with
the nose inclined slightly down. If necessary you can correct the CG by adjusting the
position of the flight battery (preferable) or by adding nose or tail ballast. Before the
first flight check that all the control surfaces are exactly at centre (neutral setting) with
the transmitter trims central.
Control surface travels for normal flying
Ailerons
12 mm up, 12 mm down
Elevator
18 mm up, 18 mm down
Rudder
20 mm right, 20 mm left
Flaps
take-off: 7 mm down
Flaps
landing: 23 mm down
All stated travels are measured at the widest point of the control surfaces.
We recommend that you set 20% exponential travel (Expo) on all the flying controls
at the transmitter.
Important:
When fitting and adjusting the various linkages you should ensure that they move
freely, without binding, are able to move to their full extent - including trim travel - and
are not obstructed mechanically at any point.
