The 52 is a delightful aeroplane and a superb aerobatic trainer.
HOWEVER if a spin is allowed to develop and go flat, recovery can be prolonged, which in turn CAN lead to confusion.
Anyone doing aerobatics in a 52 and who has not read our short paper on 52 spinning should do so. Drop us a line off list, and we will send you a copy.

So a developed spin will/can go flat? That could be considered a bad habit i suppose. But not getting out of it (or not having enough altitude to recover) would be a bad piloting habit.
I suggest you guys do the following to finally put this nomex issue to rest. Build a big fire. Half of you dress in nomex and half in corduroy (or whatever you wear when you fly). Then take turns jumping through the fire until somebody bursts into flames. The losers will concede to the winners.

I volunteer to manage the experiment and keep the records!

Scooter,
Even this I would not class as a bad habit. For recovery people often give
up too soon. When the recovery takes time they try something else. Here is
my take on recovery from flat and accelerated spins in a 52.
After the nose has come up the plane is shaking and the ailerons are in, now
comes time for recovery.
***** Close throttle ******
Full forward and in spin aileron at the same time as applying full rudder.
You may think that you have applied full control but keep pushing there is
more. The stick and pedals are real strong you wont break them, and keep
them there. When the rotation stops IMMEDIATELY remove the rudder and center
the aileron otherwise you will cross over to inverted real fast, center
elevator as needed. At about 200 kph start to recover to SAL flight. Best
tip on which rudder pedal to push (inverted or right side up) look at where
the ground is disappearing to that is the pedal to push. Now this is just my
attempt to put into words a method that I was taught, it is a lot more
interesting when doing it for real.
Gennady Elfimov (www.skytrace.co.uk) said that in Russia they experimented
with the standard Muller Beggs recovery and found this method above to be at
least 500 ft more efficient in altitude loss.
Now I really must say here again that email is not the way to learn
technique the only way to do that effectively and safely is to find someone
that knows what they are doing and learn from them. I asked you before which
state are you in there are numerous people out there that would show you
technique.
As for a developed spin going flat I would disagree. Sure a spin can get
very stable and inertia becomes a factor but it will not go flat without the
engine. If you do a flat you will be shocked by just how much the nose comes
up one mans flat is another mans stable.

As a point of reference this link shows the skytrace training program.

This is based on the DOSAF system.

Richard,
How much do the spin characteristics change, if you don't have the Russian radio in the back?

Not much, other than your observer on the ground won't have to speak a foreign language anymore.
Sorry........
