First Flight (continued)
With
right
hand, grasp the glider directly behind the vertical stabilizer on the bit of fuselage
that extends
aft
of the rudder. Pull the glider back against the elastic just enough to tension
the rubber and prevent the band from slipping off the launch lug.
Raise your
left
hand and outstretch your
left
arm out and away from your body.
Rotate the top of the scimon glider
right
, away from your body, so that the main wing is
nearly perpendicular to the horizon and the open portion of the “U” shape made by the
wings oriented to the
right
. While still grasping the glider drop your right hand down and
away from your body to build tension.
Observe three things prior to release: One, the angle of the elastic; adjust hand positioning
until the elastic and glider is inclined (aimed) at an angle of approximately 60-70 degrees.
Two, again take note of the glider rotation angle (near perpendicular to the horizon - top of
glider rotated away from body to
right
). Three, length of pull, build power slowly 24 inches
of stretch (distance from launch stick in
left
hand to launch lug on glider) should be plenty to
start.
Ready? Release!
Never
launch scimon at another individual or when bystanders are not safely away from the
action. Flying gliders tends to attract the interest of children and pets. Keep these
individuals safe by keeping them involved or safely restrained away from the activity.
Never
launch scimon with wings level at the horizon as the model will loop and potentially
crash nose first into the ground upon exit of the loop (infamous figure 9).
Never
launch scimon with wings inverted (“U” opening to the ground) this will result in the
need to build a new scimon glider!
2.
Launch.
When setup, aimed, and released properly; your scimon will climb briskly in a tight
right-
hand
(clockwise) corkscrew pattern. Vary the amount of power input given in your setup to place the
flight apogee (the highest point of climb) as close to the celling as possible. High scores start with high
launches but don’t be tempted to shoot for the moon on your first flight. Build launch power as you
build flying experience.
3. Transition.
As scimon approaches, and proceeds through, apogee it should be slowing to glide speed
and will flip or roll to the
left
beginning the glide stage of flight. A big stall (abrupt climb, nose drop,
and altitude loss) following transition can be indication that too much momentum was carried through
the transition, try reducing the launch angle by several degrees. Lack of altitude can be influenced by
input power on launch and launch angle, increase one or the other, one-at-a-time.
While the transition
will be influenced by glider trim (especially the rudder angle) we have found it to be a mix of proper
glider setup and proper launch angle. Experiment with both until you can achieve consistent results.
4. Glide.
After the
left
flip at apogee the scimon begins a descending
left-hand
(counter clockwise)
pattern until it lands. Your scores will be higher if you can trim scimon for a slow descent.
