POWERED FLIGHTS
Wind up the motor with approximately 50 turns
(wind clockwise looking at the front of the model)
and launch it into the direction of the wind (if
present). This should achieve a gentle powered
glide. Aim for a gentle left turn by adding a tab
made from clear acetate (the clear film that you
might find on a chocolate box ‘window’) to the
trailing edge of the rudder. Adjust it towards the
left to make the plane turn left and to the right if
the left turn is too sharp. If the left wing ‘dips’ and
the model spirals in, then add an acetate tab to the
left hand wing and bend it down a little. Gradually
increase the turns on the motor in steps of 50 turns
up to approximately 250 for the short simple loop.
At each step make adjustments to the tabs to
control the flight pattern. If you struggle to get your
model to fly well, then check for warps in the flying
surfaces of the model. These can be removed by
twisting them over a bowl of steaming water.
