HpH 304CZ as first sailplane

I agree that the Grob is the least "304-like" of the aircraft I
mentioned, but it will accelerate quickly enough to make the important
points about spiral dives, redlline speed and recovery, even with the
spoilers out, and will float well enough to emphasize the issues of
speed control on landing. I agree that a Duo, K-21 or DG-1000 would be
better for the purpose, but these are less available in the local
rental/instructional fleets.

I don't understand "redlline speed and recovery, even with the spoilers
out". The 303 has terminal speed limiting brakes, doesn't the 304?
My 303 doesn't quite make it to manuevering speed with the brakes out and
the nose pointed at the ground. The POH mentions a 2G deceleration if you
pull it all out at redline. Have no intentions of trying that one on my 29
year old lady.

I wasn't aware that the brakes on the 304 would limit speed to below redline
in a vertical dive. If true, the ship goes way up in my estimate of
suitability for a new-to-glass pilot. The manual on my LAK-17 says that the
brakes can be fully extended at redline but to "expect high aerodynamic
forces". I haven't tried it either.

Yes, this is one of the cool things about older ships--I understand it used
to be a requirement of the class.
Again, I don't know about the 304, only the 303.

It was my understanding that it was a requirement that the airbrakes limit
speed to less than Vne even at extreme dive angles. However, I wouldn't
count on that. I seem to remember reading something from Schweitzer
claiming that although their gliders were compliant with that, many of
their competitor's weren't. They also went on to say they thought the
requirement was unreasonable and that they felt their competitor's
performed fine within a reasonable pitch angle (45 degrees?) Point is,
don't try this at home...

Nope, the 304 airbrakes are not terminal velocity limiting. If you've
flown one, you'd think so, but the HpH team says no. The manual says
to expect a 2g decelleration if you pop those bad boys at high speed.
It is correct. Make sure your stuff is stashed or it ends up by the
rudder pedals. Ok, it was a sandwich...
