  In regards to the "new" primary category - all I see is a name change.  Big 
deal.  I'm not sure what difference a new name will make but it sure 
doesn't bother me.

I also see that the Primary category has a new sequence this year.  That's 
not different per se.  They could have done that without the name 
change.  Known sequences have changed from year to year in the past.  What 
is different is the absence of a spin and the presence of a half Cuban. The 
absence of the spin together with no boundary penalties is thought to allow 
P51's and the like.  Hmmmm.....interesting.  Actually, I don't see anything 
in the present or former rules that would prevent a jet or warbird from 
entering the contest.  Any maneuver prohibited by the AFM, can't be flown 
in the contest.  One could still have entered their P51 (or whatever) in 
Basic and just omit the spin (taking a zero) and fly the rest of the 
sequence.  Under the new rules, one could enter the P51 without taking the 
zero.  On the other hand, having the spin in the sequence provides more 
assurance that entrants will have been practicing them.

Having the spin in the primary sequence doesn't really provide much 
assurance than a stranger showing up for his first contest could actually 
fly a safe spin or recover from an inadvertent spin.  I have seen first 
time competitors totally screw up their Basic spin and have to be saved by 
their safety pilot.  Scary.  I have also seen plenty of hammerspins and 
loopspins.  Even some snaprollspins.

When I showed up at my first contest, nobody knew me or had ever seen me 
fly.  I brought a single seat airplane so I couldn't accept a safety 
pilot.....and I wanted to fly Sportsman.  What they did was watch me like a 
hawk during my practice flights and assign me a "buddy" - one of the 
unlimited competitors - to be my mentor (and maybe to make sure of my 
attitude, find out about my training experiences, etc.)  I think they 
relaxed a little when I came in second in the category after my first 
flight (finished 3rd after 3 flights).  Note that I did have about 25 hours 
of acro dual in Super D and S2B + 35 hours solo practice in my Yak55 before 
showing up at my first contest.

I guess my point is that the presence or absence of a spin in Primary 
doesn't provide much guarantee of safety.  In the past, we've relied on a 
social process, not rules, to provide safety for first timers.  So far, 
this has worked pretty well.

I'm not so sure about the wisdom of allowing airplanes that aren't approved 
for spins to compete.

I don't want to fly aerobatics in an airplane in which spins are prohibited 
as I know all too well that a spin is a possible outcome of many aerobatic 
maneuvers.  I don't want to see my friends do this, either.  I also don't 
think I'd like to be CD, tech inspector or CJ at a contest where such an 
airplane was entered.
