Judging and FAI P-05 and F-05

[Troy Newman]

My comment was that we in the USA are judging the spin that model is crabbed 
into the wind.

The TEAM Selection last year, NATS last year and so on the pilots were told 
that the crab was OK. The

AMA rules indicate the model must maitain the crab angle and not drift until 
the stall occurs.  BUT The FAI rules tell us..... as the model slows and 
before it stalls the maintaning of the crab angle becomes determental to the 
geometry of the manuever. Since the model is in a near stalled condition it 
the wind drift is OK! Its the crabbing into the wind that makes the spins 
look funny and often sometimes hard to judge...This is extreme conditions. 
Now I would also acknowledge that drifting out to 300meters makes it tough 
to judge too!


So the model fuse basically stays square (parralell in this case) to the 
flight line all the time...as the model approaches the stall break in the 
spin.

I'm not pushing for one over the other in terms of what is correct. I am 
pushing that FAI needs to be judged on a standard at least equal to if not 
better than it is everywhere else in the world. The rules are what they are 
and input beyond that is not fair to the pilot expected to fly it.


These power point documents were actually produced by Bob Skinner the 
chairman of the CIAM committee for F3A. He is from South Africa I believe.

They were posted on the British site. Bob also made similar documents for 
the 2003 sequences.
