Trainer 40 Instructions
Fitting the fuel tank
25. Identify the fuel tank and its
hardware. Following the diagrams
included, assemble the fuel tank
ensuring that the clunk is free to move
from side to side and up and down. This
will ensure that fuel is delivered
to the engine regardless of the model's
attitude. Tighten the bung screw to
seal the fuel tank.

26. Pass the fuel tank through the wing opening in the fuselage and into the nose of the model, the neck of the tank protruding into
the opening at the centre of the metal engine mount. Using the foam packing supplied with the fuel tank, support the tank by
packing it around the tank bay.

27. We recommend the MDS 40 PRO
two stroke engine for powering the
Trainer 40. This powerful, easy to handle,
quiet engine will give many hours of
trouble free, smooth running.
Identify the engine mounting hardware
consisting of two metal clamping
plates, four mounting screws, four shake
proof washers and eight nuts.

28. Connect to each of the fuel tank outlets a 100mm length of fuel tubing. Their free ends can be taped to the top of the fuselage
to keep them temporarily out of the way. With its carburettor removed, place the engine in the engine mount. The engine's
mounting lugs should sit over the grips moulded into the mount.
