Note:
The servo mounting frame does fit in the fuselage opening! Turn it around carefully and you
will find that it will slip neatly into place. Don’t be tempted to force it or to sand away too much
material which will result in a poor fit.
For the electric powered KULT Mini DUO , insert the servo board only after the motor mount has
been installed to ensure sufficient space for motor, ESC, and flight pack. The two identical supplied
fuselage frames are carefully aligned and glued together to form a 6 mm laminated frame which is
installed under the servo mounting tray – to provide a battery mounting tray.
Tip:
The receiver is best located behind the flight pack and as far away from the ESC as possible.
V-Tail Linkages.
Carefully measure the length of the Bowden cables - to reach the servo position, always
keeping mind to minimise the length of unsupported control linkages. Now install a Z-bend
in the tail end of the two wire push-rods and insert into the Bowden cable from the tail. Cut to
length, clean the ends and solder the two clevis adaptors onto the ends of each push-rod,
screw on the metal clevises and lock-nuts and connect to the servo output horns.
Motor Mount (*)
Prepare the area where the motor mount is to be bonded to the inside of the fuselage nose with a
course abrasive paper (80 grit) to ensure a good bond. The motor mount should be installed about
1mm back from the edge of the fuselage nose and installed so as to provide 3° down-thrust and 2°
side-thrust (depending upon your choice of drive system). Carefully position the motor mount in place
and secure with a few drops of instant adhesive before finally bonding in place with a bead of suitably
thickened epoxy.
Tip:
Fit a long nylon bolt through the centre hole in the motor mount and use the protruding part pf
the bolt as an aid to adjusting the precise amount of down-thrust and side-thrust. The bolt also serves
as a useful handle while positioning the motor-mount in place.
With the motor temporally installed, fit the propeller yoke and spinner and check the alignment of the
fuselage nose with the spinner. Carefully grind the front of the fuselage nose to match the profile of
your chosen spinner.
