| Subject: | Initial Poor Rocket Performance |
Hi Guys,
As you know (if you've read here a while) my father has a HRII, the
first and only in the UK, a 10yr labour of love and its almost through
its 10 flight pre-test flight envelope, which is good.
However so far the performance is quite hitting the right
marks....Initialy thinngs looked great, with the first flight getting
180-200mph off half throttle....However opening her up has only yielded
220-230mph, which from what i gather is somewhat off the mark for full
bore straight and level ??? RPM is a tocuh over 2500
The engine is an IO-540-D4A5, which was a new build by Norvick, there
wasn't a stock C4B5 available and an extra 10hp can't hurt. The prop is
a Hartzel HC-M2YR-1BF/F8475D-4. The governer is by Mccauley, i don't
have the model no. to hand, but i don't know if this is the weak link.
Anyone use this engine/prop combination, if so whats you governer/set-up ?
Any ideas ???
Thanks,
Lee

It sounds like your governor needs setting up. It should go to 2700 rpm
for max hp. 2500 is 200rpm too slow.

Seems about right. John Harmon's brochure claims 230 mph cruise. I flew
with him many years ago and that is exactly what we cruised at. We are
talking Indicated airspeed which as you know will decrease with altitude.

| Subject: | 8/32 screw with a 6/32 head |
Someone recommended I use an 8/32 screw with a 6/32 head to hold the
fuel tank to the wing. He said they can be obtained from German
aircraft hardware. Google search does not locate such a source. Does
anyone know of a source for this item?
TIA

Hi Jim,
They were probably referring to Genuine Aircraft Hardware...I can get
you
the number if needed. I would like to discuss what you're doing if you
get
time.
Good Luck!!

Neil Dickey Question:
Hi, I am in Greenwood, MS. and have purchased a kit from one of your
"neighbors" at Livermore, Steve Atchinson, that he has decided not to build. I
am an
A&P-IA, 48 years in the business, own and operate Midsouthjet Corporation, a
maintenance facility for turboprops and jets at GWO. Have built an RV 4 and
Miget Mustang and restored numerous certified airplanes over the years. So
much for the "bio" for now, just wanted you to know where I am coming from. My
question for now is, Do you know of any builder that may still have a
fuselage jig they might sell or otherwise dispose of? Sure would be nice not to
have
to go through that again. Thanks. Neil
