Wrap your receiver and battery (if 
using a separate battery for the 
receiver) in dense foam packing 
and install in the fuselage under the 
tank. The battery’s final position will be 
determined once the model has had its 
balance point checked.

To ensure that the trailing edge 
of the wing is not crushed by 
the wing mounting bands, two 
plywood reinforcement plates are 
used on the top surface. Holding 
the first plate in position on the 
wing with its rear aligned to the 
trailing edge, mark its shape on 
the surface of the wing using a 
water-soluble/non-permanent felt 
pen. Trim away the covering inside 
the marked line and glue the plate 
in position. Repeat for the second 
plate.

COMPLETING THE TUTOTR 40 II

Your radio switch (or 
if you are using an 

ESC with a switch) can now be mounted. The 
radio tray has a pre-cut slot should you wish to 
mount the switch internally and operate it with a 
bent wire through the fuselage. The simplest way 
of fitting the switch is simply mounting it through 
the left-hand fuselage side (on the opposite 
side to the exhaust). Using the switch plate as 
a guide, mark and drill the mounting holes. Now 
cut a suitable slot for the switch. Mount using 
the screws supplied with the switch.

Stage 31

31.1. Use the switch as a guide for cutting

31.2. Fit the switch in the fuselage side

Stage 32

Locate the  pre-drilled holes 
for the wing mounting dowels. 
Using a sharp knife, trim the 
covering away so the dowels can 
be pushed through the fuselage 
sides. Ensuring they are centrally 
located in the fuselage, run some 
medium super glue around each 
to secure.

32.1. Trim away the covering

32.2. Insert the wing dowel

Stage 33 

33.1. Mark the position of the first plate

33.2. Trim away the covering

33.3. Repeat for the second side

33.4. The completed wing

Stage 34

34.1. Receiver battery wrapped in foam

34.2. And installed in tank bay

Stage 35

Before starting the final set-up of 
the Tutor 40 II, switch on the radio 
and ensure that all trims are in 
their neutral positions. Check that 
the ailerons, elevator and rudder 
are centred. If any adjustments 
are needed, do this by unclipping 
the appropriate clevis and turning 
it clockwise to shorten the linkage 
or anti-clockwise to lengthen it. 
Only when each control surface 
has been centred mechanically 
should you begin adjusting the 
surface movements (or control 
throws).
