Test flying
The Hot-Shot should be given a test-glide or two before the first
powered flight.
If you have fitted a motor pod, remove it for the test-glide
procedure. This is quite safe, as the pod produces no change
in the model's CG.
Wait for a day with as little breeze as possible for test-gliding the
Hot-Shot. For the first few flights seek out a large, open field
devoid of obstructions (trees, fences etc.).
Carry out one last check of the working systems.
Grip the glider in one hand at its balance point, with the
transmitter in the other hand. Hold the model level at around
head-height and point it directly into wind.
Trot forward for a few paces and give the model a powerful
launch straight ahead, with the nose slightly above horizontal.
Use the controls if necessary to place the model in a steady,
even glide, and adjust the trims if necessary - flight path „A".
If the model follows flight path „B" apply down-elevator to
correct; if the model follows flight path „C" apply up-elevator to
correct.
If you need to adjust the trims to obtain a flat glide, adjust the
pushrod lengths when the model is back on the ground so that
you can return the transmitter trims to centre; this ensures that
full trim travel is available for subsequent flights.
Repeat the test-glide procedure until you are satisfied that the

Hot Shot
model is trimmed correctly, but take care to use the controls as
little as possible while the model is close to the ground.
Once the model is trimmed correctly for the glide you can
confidently fit the power pod and try a powered flight.
Keep well clear of the rotational plane of the propeller when
the motor is running, as the spinning blades can easily
injure you.
Start the motor, adjust it carefully and give the model a powerful
launch exactly into wind, with the nose inclined slightly up.
You may find that you need to apply moderate up-elevator to
prevent the model diving (flight path „C").
Note that flying wing model aircraft tend to respond more
directly to elevator commands than conventional models, so be
gentle with the elevator stick when correcting the flight path.
Allow the Hot-Shot to fly in a straight line; don't try to turn it when
it is close to the ground.
Prevent the model climbing at too steep an angle otherwise it
could stall.
Adjust the trims if necessary to produce a steady climb under
power.
Land the model on the glide after the motor has stopped.
