TO MAKE UP AND FIT THE MOTOR
The motor consists of the rubber strip provided.
This strip is more refined than that used in rubber
bands and is very stretchy, allowing it to hold lots
of energy. A single loop should have enough
power for the model if it is built lightly as per the
instructions. Contrary to popular belief, the rubber
motor is not designed to hold in the nose plug,
and motors that are much longer than the distance
from the propeller hook to the rear peg are used
by experienced modellers. This requires a geared
winder to ‘stretch wind’ the rubber motor. If this
is your first model and you do not have a stretch
winder, tie a knot in the rubber to make a loop that
is roughly the distance between the peg and the
hole in the nose. Wetting the rubber makes it easier
to tie a knot, however, do not pull the knot too tight
otherwise it can tear. Once knotted, apply a tiny
drop of cyano to the end ‘ears’ of the knot, taking
care to avoid putting cyano on the actual working
part of the rubber. To make your rubber motor
more efficient it can be lubricated with castor oil or
spray silicone trim polish that can be bought from
motor factors.
Put the rubber loop down into the nose of the
model, lower it down to the peg position and trap
the loop with the peg, then connect the other end
to the motor hook, and fit the nose plug.
TO BALANCE THE MODEL
Referring to the arrow on the plan labelled ‘balance’,
hold the model with your fingertips under the centre
section at that position. It is likely that the model
will want to tip backwards. If it does, add Blu-Tack
or plasticine to the nose of the model, adjusting
the amount until the model balances at the correct
position with the tail plane approximately level.
