|Half Reverse Cuban Eight: Model pulls up
and executes one-eighth (1/8) inside loop to 45 degrees, hesitates, does
one-half (1/2) roll, hesitates, then performs five-eights (5/8) inside loop
back to level flight in the opposite direction as entry.
|Read that description carefully. Here's how it's supposed
to be done.
- At the completion of Straight Flight Out, up elevator is smoothly
added to make the plane fly a constant radius 1/8th inside
loop to a 45 degree climb.
- Fly a straight line in a 45 degree climb.
- Execute a one-half roll to inverted flight. You will need to add
down elevator at the completion of the roll to maintain the 45
degree up line
- Fly a straight line (inverted). This line is still on the same 45
degree up line and must be the same length as the line immediately
before the roll.
- Execute a five-eights (5/8) inside loop to level upright flight.
Loop must be of constant radius, and radius must be the same
1/8th loop at beginning of maneuver. Exit altitude must be the same
as entry altitude.
|Now for the downgrades:
- Loop segments not round with the same size and radius.
Both loop segments (1/8th and 5/8ths) must be of equal radius and
must be ROUND!
- Model not at 45 degrees before and after half roll.
Model must climb at 45 degrees. If the climb appears to be 45
degrees to the pilot, it's too shallow! That's because you're
looking at it at an oblique angle, not straight on. If it is a true
45 degrees, it will appear more like 55-60 degrees from the pilot's
- Changes in heading in loop segments or after half roll.
Model must remain parallel with the runway throughout the entire
- Half roll not centered in 45 degree line.
The two straight lines must be of equal length for the roll to be
- No hesitations before or after half roll.
If you skip either straight line segment (before or after the roll),
deduct TWO points!
