You may need to sand back the front face of
the fuselage slightly to obtain an accurate
transition to the spinner backplate. Please
work slowly, removing material in small in-
crements, and your reward will be a perfect
transition.
•
The motor can now be screwed in place
permanently, and connected to the speed
controller. Motor polarity must be correct: the
best method is to check that the motor spins
in the appropriate direction before installing
it. Prepare a small piece of hardwood by
drilling a small central hole in it, and push this onto the motor shaft to make it easier to detect the
direction of rotation. Do not use the propeller for this: injury hazard!
•
Assemble and install the folding propeller, hub and spinner following the instructions provided by
the manufacturer.
•
The speed controller can be attached to the fuselage side or under the battery plate using a small
piece of hook-and-loop tape. Secure the cables between controller and motor in such a way that
they cannot come into contact with the rotating parts of the motor. Don't wrap the controller in
foam, as this prevents air flowing round it, and could cause it to overheat.
Final work
•
Adjust the position of the flight battery to set the correct Centre of Gravity (65 - 76 mm aft of the
wing root leading edge). This range is safe for the initial test-flights. Later you may wish to adjust
the CG to suit your personal preference - but not by more than +/- 5 mm.
•
Fix the battery in its final position using hook-and-loop tape, and mark its exact location to ensure
that it is in the same position for subsequent flights.
•
Check the control surface functions, and set the travels as follows:
Rudder, right-hand turn:

The first flight
•
Once you have completed all the checks, there is nothing to stop you carrying out the model's first
flight. If you have little or no experience in model flying, we urge you to join a model flying club and
ask a proficient model pilot for assistance: he will carry out the initial test-flights for you, and then
help you to learn the art of model flying step by step.
•
It is also possible to learn to fly without outside help: first wait for a day with little or no breeze.
Launch the model with a firm push forward into any wind, keeping the wings level and the nose
angled slightly above the horizontal. Allow the aircraft to climb at a shallow angle, initially using the
elevator only to adjust the rate of climb. Don't let the model slow up too much. If it turns to one
side, gently move the rudder in the opposite direction to return to straight flight.
•
Once the model is at a safe altitude, switch the motor off and allow it to glide. Use the controls
very gently at first until you feel familiar with the aeroplane's response to commands. Don't get
