Please correct me if I am wrong.

There is still no information that I could find on how the PCAS part
of the PowerFlarm will behave in a thermal full of gliders equipped
with Mod C transponders and PowerFlarms.

I would like to hear how would this unit be usable in such a
situation?

There is no way signals from Mod C transponders could be correlated
with FLARM so the PCAS would just get crazy and the unit unusable,
correct?

And what about a similar situation where gliders are only equipped
with Mod C transponders, I guess the same outcome the unit would be
unusable due to many signal sources in small area. I already
experienced this with Zaon MRX so I know this is the case.

So, how will it work? Anyone truly knows?

What I want is a pure FLARM! I don't need the annoyance of a PCAS when
I am in a thermal full of gliders equipped with Mod C transponders. I
also don't need ADS-B for a while until it will really be usable. Why
do I need to be early adopter of the ADS-B when I want to be an early
adopter of FLARM.

This box looks to me was designed for power pilots who don't fly very
close to a bunch of other aircraft equipped with transponders then the
PCAS is not a problem.

I am not about to purchase another annoying instrument I already have
one PCAS. It is great outside glider congested areas but not in a
contest. So unless I hear the PCAS issue is resolved in some way I am
not going to buy a unit to find out it is not doing what I need to do.

I am waiting to be corrected with FACTS.

This has already been discussed in threads here. As you point out PCAS
cannot work in crowded gaggles - so you disable the PCAS alarm in
those situation. As I've pointed out before it's not just that it will
be annoying, it is that the Mode C transponders fundamentally wont'
work properly in crowded gaggles. There is no other way "resolve" this
issue, so you turn it off. This is a product designed to work in
contest environments, the developers understand these issues.
