[NSRCA-discussion] Wind correction

[Don Ramsey]

John,

When flying into a maneuver, the wings must be level.  Straight and level 
flight is defined in the rules as wings level so, flying with a wing down is 
not acceptable.

In AMA for stall turns the track of the model must be vertical. That 
requires leaning into the wind in a crosswind.  As the model slows there is 
more lean.  Then comes the problem.  As the model slow below the wind speed, 
the track will start to drift and that is to be downgraded (under the 
current rules).

FAI has this problem fixed in their rules.  As the model pulls up for the 
stall turn a crab angle (lean) is established.  That angle is held for the 
entire vertical and the track is allowed to drift without downgrade.  In 
order for the judges to be more consistent in scoring stall turns for AMA 
classes this rule should be adopted.

I just finished an article for the K-factor about this subject.
Don
