[F3A-Discussion] Clarifications on certain maneuvers in the P and F sequences

[Jon Lowe]

Drek,
Good info.  Probably needs to go on the main NSRCA list also as judging points.

Incidently, the current Model Aviation (May 2012, page 6) has some disturbing info about the AMA participation in the FAI program.  There has been complaining for years within AMA about the cost of AMA participation in FAI (huge, because of the number of active modelers in the states), and there was some talk about pulling out of FAI awhile back.  I know that help from AMA to the various teams was cut back, as long as two years ago.  A guy in our club was on the US team for FAI RC Scale a couple of times, and AMA cut out support for them. AMA told them that they would support teams on their past record in world competition, and since scale had not placed that high, they wouldn't get support.  Have you gotten any indication on how AMA is looking at the F3A program and how cutbacks might affect the US team?

Jon

Subject: [F3A-Discussion] Clarifications on certain maneuvers in the P and F sequences


I've had several conversations with different people about maneuvers P-13.03 (Consecutive three 1/4 Rolls followed by consecutive three 1/4 rolls in the opposite direction), F-13.05 (Roll combination with consecutive 1/4 roll, two snap rolls opposite, 1/4 roll), F-13.09 (45 degree upline with consecutive four 1/8 rolls followed by 1 1/2 snap in opposite direction) and F-13.11 (Clown dance with 1/2 loop, inverted 2 1/2 turn spin and two 1/4 rolls down).


In P-13.03 - there is no pause between the end of the 1st three 1/4 rolls and the start of the second set of 1/4 rolls - the reversal must be immediate.  I think a lot of people are thinking of this maneuver as a 3 of 4 point roll followed by a 3 of 4 point roll opposite and thus want to put an extended line between the two sets of 3 of 4 point rolls.  Since these are three 1/4 rolls, there is no requirement to extend the line after the 3rd 1/4 roll to make it "symmetrical" and thus the roll reversal should start immediately after the plane finishes the third 1/4 roll.


F-13.05 - There is no pause after the 1st snap and the 2nd snap should happen immediately after the 1st one.


F-13.09 - This is just like P-13.03 in that the 1 1/2 snap roll must happen immediately after the four 1/8 rolls.  There is no line between the end of the fourth 1/8 roll and the snap roll.


F-13.11 - Since this maneuver contains 2 elements (the 1/2 loop and then the spin), the center of the maneuver should be exactly in the middle - in other words, the distance to the outermost radius of the 1/2 loop (from the middle) is the same as the distance to the start of the spin entry.  As an example, this would be identical to the placement of a double immelman on center - 1/2 the maneuver will be to the left of center and the other half of the maneuver will be to the right of center.
