Building Instructions.
Fuselage Construction
Build the motor and battery inner fuselage box.
1.
If the standard ‘B’ type VMC
*
motor is being used (or similar), locate the motor mount ‘F2-B’ from Sheet 1
and former/mount ‘F2-C’ from Sheet 2. If the more powerful type ‘C’ VMC
*
motor is being used only ‘F2-C’ will
be required.
If using the ‘B’ type motor, insert the four supplied captive ‘T’ nuts into the pre-drilled holes from the rear of ‘F2-
B’. Alternatively, if utilising the ‘C’ type motor insert the ‘T’ nuts into the pre-drilled holes from the rear of ‘F2-C’.
*
‘B’ Type motor length is 28mm (min) to 33mm as measured from the back of the motor mount to the face of
the propeller mount, and the ‘C’ type motor is 37mm (min) to 41mm.
2.
Locate and remove plywood formers ‘F1’, ‘F3’, ‘F4’, ‘F4’, ‘F7’ ‘H1, ‘H2’, ‘H3’, ‘H4’, H5 and the two plywood
front fuselage sides from Sheet 1 and Sheet 2.
3.
Dry assemble, (
DO NOT APPLY ANY GLUE UNTIL INSTRUCTED TO DO SO
) ‘F3’, ‘F4’ and ‘F7’ with ‘H4’,
using the lower slots on ‘F3’ and ‘F7’ with ‘F4’ being assembled onto the middle slot on ‘H4’.
4.
Locate ‘H3’ and insert the two tabs into ‘F4’ with its front tab resting on ‘F3’.
5.
While holding the parts together, place the assembly onto a plywood fuselage side ensuring that the tabs fit
into their respective slots.
6.
Insert ‘H5’ into place between ‘F4’ and ‘F7’.
7.
Place ‘H1’ with its two tabs into ‘F3’ and either side of the tab on ‘H3’ and into the tab on the fuselage side.
8.
Insert ‘F2-C’ into place into the ‘C’ slot on the fuselage side and onto the tabs on ‘H1’ and ‘H2’.
9.
Place the second fuselage side into position ensuring all the tabs on formers ‘F3’ to ‘F7’ and ‘H3’ to ‘H5’ are
correctly located in their slots.
10.
Weight or clamp the fuselage sides together from ‘F4’ to ‘F7’. Make sure everything is square and that the
sides are aligned before wicking Cyano (CA) glue into all the joints and tabs –
DO NOT APPLY GLUE TO ANY
FORMERS FORWARD OF ‘F3’.
11.
When the glue has fully set, bring the front fuselage side together ensuring that the tabs on ‘F2-B (if used)
and ‘F2-C’ are positioned in their slots. Add former ‘F1’ to the front and clamp or tape the front together. Check
that everything is square and aligned and wick CA into the joints and around the tabs and allow the glue to fully
set before removing the clamp/tape.
12.
Locate ‘F6’ and stick the former into the angled slot on the top of ‘H4’. The inner fuselage box is now
complete.
Fuselage and Fin Build
1.
Locate and remove the following formers – ‘F8’ from Sheet 1, ‘F9’ and ‘F10’ from Sheet 4 and the right and
left hand balsa fuselage sides from Sheets 7 and 8.
2.
Dry assemble the balsa fuselage sides onto the inner fuselage box, ensuring that the right and left sides are
correctly positioned (each is marked as ‘LH’ or ‘RH’). Clamp or tape in place.
3.
Dry assemble formers ‘F8’ and ‘F9’ (both with ‘FRONT’ facing forwards) into their slots and then bring the
rear of the two fuselage sides together and insert former ‘F10’ (fin locating mount) with the etched guide lines
facing upwards into the slots on the top of the rear fuselage. Ensure that the fuselage sides are correctly
