[NSRCA-discussion] Proposed rule change

[Dave Burton]

I agree! We’ve tried to make judging too complicated with too many conditions. It’s impossible to consider every facet of a flight in the upper classes especially.

Make it simple stupid!

Excuse me if I take this off subject a little.

The hardest part about judging is trying to adhere to complex rules that often require excessive clarification, which often applies only to that specific scenario. Flying pattern is all about guiding your aircraft along an invisible line in the sky dictated by the required maneuver geometry and positioning. Most of the time wind corrected flight is required to accomplish this. Our skill, or lack of, should be based on our ability to quid our aircraft along that invisible line rather than anticipating pending wind drift that often changes substantially in heading and velocity during a single flight, heck sometimes we even get caught in a rain shower. It's not complicated, just follow that invisible line no matter what.

What do you guys think of this rule change for stall turns?

 

In the Judge’s Guide Page RCA 20 of Regulations under “Stall Turns”: 

Change  1.. Lines must have exactly vertical and horizontal flight paths.  To

1.  Horizontal lines must be wings level and parallel to the flight line.  On entry vertical lines must be wind corrected to establish a vertical track.  The wind corrected attitude of the model must not be changed as the stall is approached and any wind drift is not cause for downgrade unless the model drifts out of the maneuvering area.

 

In the maneuver descriptions under “Figure M with or without Rolls” 

Change downgrade 1 from “Model not vertical at start and finish of rolls and stall turns” to

 

1.  Horizontal and vertical lines must be flown as described under “Stall Turns” in the Judge’s Guide above.

 

In the maneuver descriptions under “Stall Turns with or without Rolls” 

Change downgrade 3 from “Model track not vertical at start and finish of rolls and stall turn”  to

 

3.  Horizontal and vertical lines must be flown as described under “Stall Turns” in the Judge’s Guide above.

 

 

Here’s the logic behind the change:

 

Once a crosswind becomes stronger than the speed of the model the model can no longer maintain a vertical track even if turned 90 degrees into that wind.  Stall turns flown as described in the changes always score better with the majority of judges.  This change brings the stall turn in line with the spin in allowing some wind drift of the model as it slows and provides a much more consistent judging standard.
