Fit the two bottom wing panels on the aluminium joiner tube, insert the root leading edge
tongues in the slot in the fuselage former, and fix the wing to the fuselage using the
plastic screws supplied.
The two wing struts can now be screwed to the brackets in the wings.
The holes in the struts must first be opened up to 7 mm Ø in order to accept the plastic
nuts.
Attach the two wing struts to the wing brackets using the plastic screws supplied. Mark
the correct length of the plastic screws and shorten them so that they end flush with the
outside of the plastic nuts.
Assembling the ULTIMATE
We recommend that you connect two 100 mm extension leads to receiver output
sockets 2 and 5, to make it easier to connect the aileron servos when rigging the model.
Fit the wing panels on the aluminium joiner tubes. Connect the aileron servos to the
extension leads, and screw the bottom wing to the underside of the fuselage as already
described. Fix the top wing to the cabane. Tighten the screws just to the point where the
wings are firmly fixed to the fuselage, and cannot shift. Don’t over-tighten them!
The top ailerons are driven by the bottom ailerons by means of link pushrods. Glue the
link rod horns to the ailerons as shown in the photo, after removing the covering film
over an area slightly smaller than the horn base.
Glue the horns to the ailerons, keeping them parallel to their longitudinal axis.
The link pushrods are based on CFRP rods, and are assembled as shown in the photo.
Connect the top and bottom ailerons using the link pushrods.
Balancing the ULTIMATE
Assemble the model completely, with the fueltank empty, and support it on both sides of
the fuselage at a point about 100 - 120 mm aft of the root leading edge of the top wing. If
the Centre of Gravity is correct, the model will hang level, with the nose inclined slightly
down. If necessary, fit lead ballast to nose or tail until the model balances correctly.
Before the first flight it is essential to set all control surfaces exactly to centre (neutral)
when the transmitter trims are also at centre.
Control surface travels for normal flying
Ailerons
20 mm up, 20 mm down
Elevators
30 mm up, 30 mm down
Rudder
30 mm right, 30 mm left
We recommend that you set 30% Exponential on all control surfaces 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.
When you move the rudder stick to the right, the rudder should also deflect to the right
(left stick: left rudder). Pull the elevator stick back towards you, and both elevators must
deflect up (stick forward: elevators down).
If you move the aileron stick to the right, the right ailerons should rise, the left ailerons
fall. When you move the throttle stick forward, the motor should run to the full-throttle
position, i.e. the carburettor barrel should be fully open. Move the throttle stick and trim
