Battery Pack - Opitec Wasp Quick Start Manual

Installing the motor, wiring and batteries
Solder the cables (16) on the poles of the motor (15) and then to the switch and poles of the re-chargeable Solder
the cable (16) on to the motor connection (15) and the wires on the switch (17) as shown in the plan and connect
it to the battery pack. The battery pack ( Order separately article no.208530) is secured with a single layer of
sellotape or with a hot glue gun. The pre- wired switch is fixed with an all purpose glue. Once the propeller has
been added (18) the Wasp model is ready to fly.
The battery pack is loaded via a transformer (Article 208338). Loading time at 300mA is about 30minutes. To load
simply connect the transformer to the battery pack. Please read the instructions supplied with the transformer.

Balancing and trimming
Hold the wings with your finger tips on the end on a flat surface, let them go and note which way they fall, which
wing is heaviest. Place a small piece of lead or nail in the lightest wing end
The Centre of Gravity lies 43mm from the front of the leading edge. Hold the model under the wing tips at the C
of G and see how it balances. It is correct when it dips slightly down at the nose. To arrange this, adjust the posi-
tion of the batteries. The balancing must be carried out carefully as it will determine the pattern of the flights.
First flight
Fly only on a calm day or with little wind
Make sure that the wings are securely held on the rubber bands
Launch the model into the wind, with the nose slightly down , with a gentle push
If it glides smoothly and lands gently you can then try a powered flight
If on launch the model goes up steeply and then dives it is either tail heavy or has not be launched with the nose
light down. If its the former , the batteries must be place further forward
Try until a smooth flight path is achieved
If the model dives on launch, then it is probably nose heavy, here the batteries must be adjusted to the rear
When flying the model should fly in large circles, to change this adjust the tail fin in the direction you require (do
this carefully as not to snap it)
Motorised flight:
Check the wind direction ( Throw some loose grass cuttings high in the air )
Switch motor on and launch model carefully into the wind
Should the model fly out of sight- there is an address label which you can glue to the side (See page 7)!
