To Make the Pushrods to the length required;-
(1)
Make a 90 degree bend in the wire at the length required
to meet the output hole in the servo arm with the servo
centred.
(2) Now make a second bend off at 90 degrees to the first one,
left or right, in the wire at approx. 3mm away from the first
bend.
(3) Straighten the wire by gripping each side of the “Z” bend
with pliers and slowly turning until the ends are in line. Now
cut off the excess wire. The output hole in the servo arm
may have to be drilled out to accommodate the “Z” bend
wire passing through it. Adjustment of the pushrod length
is carried out by adjusting the clevis along the threaded
part of the pushrod.
An extra pushrod is supplied to allow for possible error.

A custom Sullivan 3.7 litre fuel tank made for this kit is
available from your Boomerang Jets dealer. Otherwise it
is possible to fit any container from 2 litres up by
modifying the fuselage formers as required. Ensure that
the tank is well secured by using long cable tie wraps
through the formers. Do not simply depend on the tank
bay floor for this. A full tank of fuel weighs anything up to
8 Lbs (4 Kilos) and in a negative G manoeuvre can exert
considerable upward pull.
Clean up the front opening of the air intakes as necessary. After carefully
stripping away covering from the small cutouts in the upper fuselage use
the air intakes as a guide to how much covering to remove from each side
of the fuselage, opening up the airflow openings each side and leaving a
bare wood gluing surface just a few mm. smaller than the intakes all round
ready to fix the intakes using thick CA glue. In addition the “FOD” protective
mesh supplied can be added to the inside openings of all the intakes to
prevent debris being sucked in by the turbine while running at high RPM.
As with all turbine models, it is important to prevent this if you are flying
from dusty or gritty surfaces.
