Hi Doug
The HGU 33 with the single hidden visor is the most sought after and the
lightest especially if you get made of Kevlar instead of fiberglass. Next is
the HGU 55 which has a exposed single visor and is light. You can order an
ANR kit from Headsets Inc and change it over yourself for about 130 bucks.
That is who flightsuits INC uses.
The helo helmets are OK but are wider at the ear level and heavier. You will
notice it with acro. You don't need ANR with a well fitted helmet in a CJ.
Good luck.

Doug and all,
I just bought a new helmet (from Flight Suit) and opted for a modified
HGU55, modified in the sense that it is a 55 with the 33 visor on it.
My logic is as follow; At first, I was going for the HGU84, which is
basically a 55 but built for helicopters. Helicopters helmets are built much
stronger then their fix wing counterparts, which made me think I would be
better protected with the helo style. The problems with helo helmet are:
first the extra strength is on the side since most helo crash involve a side
impact and they are almost twice as heavy as a fix wing. I am a big guy, but
tough the extra weight on my neck while doing acro was to much a down fall
compare to the extra protection (that will most likely not help me in a fix
wing crash). So I went with a fix wing. Why the HGU55 with the 33 visor
instead of the strait HGU33? Simple, the HGU55 is designed for fighter
pilots and is cut much higher in the back of the head then the HGU33 is. The
difference is the 55 allows greater head movement freedom which in my
opinion is necessary for the type of flying I do.
Total cost for an XL Painted Kevlar HGU55 (with HGU33 visor) with the top of
the line microphone, ANR, Oxygen mask connector (I need those for my Fouga)
interchangeable communication cords (2) and installation kit for electrical
power(from aircraft to ANR) comes to $1600US.
Cheers,
Dan

Dan,
You can buy one of the 55 or 33's with both the boom mic and Oxygen mask? So
it is wired for a mic in both the boom and the mask or do you switch them
out?
Also you mentioned the 55 was designed for fighter pilots. What was the 33
designed for?
Can you use the military oxygen masks with civilan O2 systems?
Thanks
Scott

The 33 was used initially for the heavy guys. (Big Ugly F(at)#$'s, Herc's
,ect). Not anymore as I understand.

Hello,
Sorry for stepping in here, but the 33 is nothing but the predecessor of the 55.
And the 33 came after the 22, which came after the 2A...
In principal, the 55 is a 33 shell (with some modifications) without the visor housing and a different liner.
The biggest advantage of the 55 over the 33 was itīs lighter weight and lower profile (no visor housing).
The drawback of the 55 over the 33 is that the visor will most likely be ripped off during a high speed eject (>500kts), thatīs why the latest development is the 68. The 68 still uses almost the same shell as the 33 (albeit exclusivley made of graphite/kevlar instead of fibreglas) but again a different visor setup.
There is a multitude of different possible setups out and it requires a careful look to identify what setup one has. On the other hand it offers a lot of room for modifications and individual setups.
And no, the 33 was just as well a fighter helmet, as are the 55 and the 68, just in a different era...

Markus,
Thanks for the info. The way I was explained was that not only was the 55
lighter, but it was cut higher on the front (for better vis) and on the back
(to allow more freedom of head movement). Don't really know anything about
the 68.
Scott,
The way it works for the O2 mask is simple; First you need to have the
helmet set up with the O2 mask receivers. Then, instead of having a separate
mic mount, simply use a T-bayonet which is nothing more then a mic mount
that fits in the O2 receiver. When you change from one to the other, simply
disconnect the mic from the helmet and connect the mask mic in. You can also
choose to have the receivers and a permanent mic. I had that on my OLD (as
in very OLD) helmet and found I had a hard time communicating because I
couldn't bring the mic close enough, but I still needed to manually connect
the O2 mic.
Hope it helps,
Dan

Dan,
Youīre right, the 55 shell is cut a bit wider in the front and higher in the back compared to the 33 shell, altough the shell shape is principally the same.
More information about the 33, 55 and 68 for those who are interested can be found at http://www.flightgear.dk/helmets.htm
Flight Suits (http://www.flightsuits.com) is the principally the only company to sell new Gentex products to the civilian world. However, for those who can do with used equipment, it is worth to look at http://www.flighthelmet.com/ They sell excellent products at fair prices!
My personal setup and recommendation for various reasons would be:
HGU-55/P with integrated chin/nape strap, ZetaLiner (from http://www.oregonaero.com) and ANR (from http://www.headsetsinc.com). It should be possible to get a decent helmet (incl. the mentioned options) with a new paint/tape job for about $600-700US.
