403-1 – Takeoff (U)

Reminders:• It is not necessary for the model to

stand still on the ground with the engine running without being held before the takeoff begins. 

• It is also not necessary for the model to reach 2 meters in the same distance as the takeoff roll. 

• The takeoff should not be downgraded for wing dips caused by air turbulence unless the wings are not immediately leveled.

The lift off should be within two (2) meters of center for maximum points.

The maneuver is complete when the model is approximately two (2) meters (6-1/2 feet) off the ground..

Downgrades:! Model jumps from the ground. ! Retouches the ground after becoming

airborne. ! Steep climb angle. ! Gallops in elevation during climb. ! Model does not accelerate smoothly. ! Model passes behind the judges line,

scored zero (0) points.

403-18 – 2-1/2 -turn spin with half roll out (U)Downgrades: ! Wing passes through vertical plane before

nose passes through horizontal plane (Snap Roll entry), zero (0) points

! Fuselage reaches a vertical attitude before rotation begins - zero (0)

! Model climbs or dives during entry or exit, 1/15 rule

! Wings not perpendicular to flightline at end of required number of turns, 1/15 rule

! Model track not parallel with flight line before stall or after recovery, 1/15 rule

! Spiral dive or pure rotation around roll axis of more than one-half (1/2) turn, zero (0) points

! Tail of model does not inscribe a cone during rotation, zero (0) points

! Over/under rotation of exiting ½ roll, 1/15 rule

Reminders:

No downgrades for the following:

• In strong crosswind, wind corrected crab angle may be large. The model may appear like it doesn’t perform 2 ½ turns. However, this is unavoidable due to near stall and preservation of track

• In strong wind, entry must be on center but exit may have drifted due to near stall during spins. This is also unavoidable in the proper execution of a near stalled maneuver

Landing area:the entire

defined runway

403-19 – Landing

The landing will not be downgraded if: The model rolls to a controlled stop within

10 meters. Wing dips which are caused by air

turbulence unless they are not immediately corrected.

The pilot “slips to a landing” to handle a crosswind condition in which case a wing will be low

Displacement of the touchdown point left or right as long as the landing is in the landing zone

Landing begins when the model is approximately two (2) meters (6-1/2 feet) from the ground.

Downgrades: ! Model passes behind the judges line, zero (0)

points. ! Model impacts the runway due to lack of flare. ! Model bounces. ! Changes in track, 1/15 rule! Model ends on its back, zero (0) points. ! Model lands outside landing zone (but still on

runway). ! If any undercarriage retracts or collapses before

the landing is complete, zero (0) points. ! Aircraft “porpoises” and/or wanders during

approach or flare. ! Aircraft lands outside the landing area or

runway, zero (0) points.

Landing zone is 30 m long and normally the width of the runway BUT not more than 30 M wide.
