F3P-C

C- 01
Take-off Sequence:
Take off unassisted and complete no more than 1½ circuits before entering the first manoeuvre. The climb out should be gradual and 90 degree turns controlled until after ½, 1 or 1½ circuits the model enters the first manoeuvre.
Judging notes.

  • Change in height to be smooth and constant.
  • Lines parallel to hall.

C- 02
Square Loop:
From upright on the baseline pass centre and pull through a ¼ loop into a vertical up line. Pull through a ¼ loop into horizontal inverted flight. Pull through a ¼ loop into a vertical down line. Pull through a ¼ loop to exit upright at baseline height.
Judging notes.

  • All radii equal.
  • Entry and exit should be same height.
  • Lines are not straight (downgrade 1 point per 15 degrees) and of equal length.
  • Manoeuvre centred on centre line.

C-03
Stall Turn:
From upright on the baseline pull through a ¼ loop into a vertical up line, followed by a stall turn into a vertical down line. Pull through a ¼ loop to exit upright.
Judging notes.

  • If the stall turn is between half and 1 wing span then minus 1 point.
  • If the stall turn is between 1 wing span and a 1.5 wing spans then minus 2/3 points.
  • If the stall turn is between 1.5 wing spans and a 2 wing spans then minus 4/5 points.
  • If the stall turn is greater than 2 wing spans then minus 10 points.
  • If the aircraft exhibits a pendulum effect after exiting the stall turn then minus 1 point.

C- 04
Knife Edge, Exit Inverted:
From upright on the baseline before centre perform a ¼ roll (either direction) into knife edge. Past centre perform a ¼ roll to exit inverted at baseline height.
Judging notes.

  • Knife edge should be held long enough to demonstrate controlled, sustained knife-edge flight (3 to 5 seconds as a guide).
  • Manoeuvre centred on centre line.

C- 05
Half Cuban Eight (No Roll):
From inverted on the baseline push through 5/8 of an outside loop into a 45° down line. Pull through a 1/8 loop to exit upright on the baseline.
Judging notes.

  • All radii equal.
  • Down line is not 45 degrees (downgrade 1 point per 15 degrees).
  • Heading change (downgrade 1 point per 15 degrees).

C- 06
360° Control Line Circuit:
From upright on the baseline at the centre line perform a 360 degree horizontal control line circle to exit upright on the base line on the centre line.
Judging notes.

  • Consistent radius.
  • Manoeuvre centred on centre line.
  • Entry and exit should be same height.

C- 07
Half Cuban Eight, half roll:
From upright on the baseline pull through 5/8 of an inside loop into a 45° down line. Perform a half roll in the centre of the 45° down line. Pull through a 1/8 loop to exit upright on the baseline.
Judging notes.

  • All radii equal.
  • Down line is not 45 degrees (downgrade 1 point per 15 degrees).
  • Heading change (downgrade 1 point per 15 degrees).
  • Half roll performed in middle of 45 degree line.

C- 08
Prop Hang:
From upright on the baseline reduce flying speed and pivot the model about the centre of gravity into a vertical hover on the centre line. Hold for 3 to 5 seconds and then pivot the model about the centre of gravity to exit upright on the baseline.
Judging notes.

  • Manoeuvre centred on centre line.
  • Height of prop hang should be constant.
  • Roll rate change during prop hand (downgrade 1 point per 15 degrees).

C- 09
Landing Sequence:
Exit the last manoeuvre and complete no more than 1½ circuits before descending to land in front of the pilot. The descent should be gradual and 90 degree turns controlled.
Judging notes.

  • Change in height to be smooth and constant.
  • Lines parallel to hall.

Maximum score = 230. Promotion = 138 (60%)
