that half of a contest score earned with the pilot’s skill to
replicate flight maneuvers performed by the full size
aircraft they chose to model.
There are nine maneuvers to each
flight round. Minimum number of flight rounds at a
scale contest is three.
Pilot practices flight plan many times before performing it at a
scale contest. Often a flight routine is thought of as a
mission. Pilot’s presentation skills during flight rounds can
contribute to a higher round score.
Judges view each maneuver, determining if it is correct compared
to description in the AMA
Academy of Model
or USSMA Guidelines*.
Regulations recommend downgrade values for failing to adhere to
specific aspects of each maneuver. The scale judges are selected for
their ability to interpret the pilot's nine maneuvers in a fair and
Judging flight routines is less subject to
opinion & bias than static judging because maneuvers are
defined in the Competition Regulations*
in a clear manner.

model should accelerate to a realistic speed, then lift
gently at prototypical angle. If model is touched after
pilot says "Now" score is zero.
2. Straight Flight Out
Model aircraft should make a straight and level flight of at least
100 meters length centered on the judges’ position.
From straight & level flight model passes judges
& performs 180 deg climbing turn away from judges,
resuming straight & level flight on opposite heading.
From straight, level
flight, model performs half roll & when inverted performs

position, & opened when normal flight resumes.
pulls into circular inside loop until 45° nose down. Hold
inverted flight until a half roll when abreast judges, 45°
upright is held until entry height is achieved when a like
circular inside loop is flown to repeat maneuver in the opposite
direction. Straight & level recovery is at same height as
entry. Model throttle may close at top of each loop.
Prototypical shallow dive is permitted.
Model approaches in straight & level flight on line
parallel with judges’ line, & then a 1/4 circle turn is
made in a direction away from judges’ line. Followed by a
360-degree turn in the opposite direction, followed by a
270-degree turn in the first direction, completing the maneuver
on original approach line.
