Murphy manuals

Bob P.,

I can understand Murphy wanting to protect their property rights, but a
few more dimensions in the manual would be nice. I am still working on
my ailerons and an example is locating the trailing edge (AIL-28). I can
make the 4 parts conform to the note: "Parallel and equal distance - all
4 ailerons." but in the back of my mind I am thinking, "I sure hope the
distance I chose mates with the trailing edge of the wing so there is a
continuous line and not a step between the two."

Terry McClary

There IS another reason - PIRACY !! Several "clones" of
early Murphy designs (which DID have blueprints) have appeared on
the market in Italy and several former Soviet countries, for
example.
The same has happened to others, like Zenair and Rans. There is
little
that a manufacturer can do to protect his work in other countries
...

Murphy has always had a policy of giving price reductions to
the
first 10 or 20 buyers of new designs, to get accelerated feedback on
customer needs/desires.

The early buyers of the Super Rebel kits got a VERY
SUBSTANTIAL
reduction in price in exchange for their acceptance that the manuals
and some parts were still under development, and that they agreed
to help the factory by providing feedback on the suggested
improvements
to the manuals. Some builders have been very helpful and supportive
....
and all are quite certain that they will end up with a very
satisfactory
airplane !!

(Having put over 50 hours on the factory Super in the last
month, flying around Ontario, Quebec, and back out to B.C., I can
tell you THIS IS ONE <GREAT> AIRPLANE !!! It is DEFINITELY the
bargain of the century in terms of price/performance !! )

All of the aircraft manuals are continually being improved,
so, naturally, the Rebel manual, after 10 years of development, is
more refined than the Super Rebel manual, which is only about 4
years
old, but both are improving at a faster rate, as Tech Support gains
experience. The factory still needs positive feedback on ways to
improve things, and are most receptive. They are planning many more
photos, and would certainly appreciate any that you could submit
that
you think would be helpful. (There are only 3 of them, and they have
over 1,500 builders to help, some daily, as well as trying to
improve
the manuals !!) I'm sure they will thank you for the help !

Mike,

Very
frustrating! I would really appreciate it if Murphy would provide
full-size
blueprints (ala Van's Aircraft) and lots of photos and assembly
drawings.
I've had several perspective SR2500 customers stop by and they are
somewhat
turned off by the lack of blueprints and photos. However, they do
like the
quality of the components.

I've recently purchased some SR2500 drawings from Gordon Hindle;

Thanks to Gordon, we actually have nice drawing of the SR2500. Why
the heck
isn't Murphy doing this?

It is ever so refreshing to know I'm not the only one having
trouble
getting information from the manual. The flaps and ailerons on
REBEL are
tied together. You are right they really need something that
includes
information detailing overall assembly so we can see how things
work
together. I was having same problem with the elevator until I went
up and
saw Waynes bird. Then it became clear. More information would
probably help
prevent a lot of mistakes and stress if we could see what kind of
tolerances
we could work with. Unfortunately I find the lack of dimensions on
drawings
somewhat disconcerting as it doesn't allow for double checking. It
means we
have to take a lot on faith and assume the manuals are correct. I
guess
that's one very good reason for this forum. It has helped me a lot,
if for
no other reason to reduce the stress !!!

Terry, the flaperons ARE the trailing edge of the wing, so as long as you
make them all the same you will be fine! Make yourself a little jig using
"spent" rivet mandrels hammered into the table or a board to hold the spar,
trailing edge and end ribs to make them all the same and square. When you
install the wings and flaperons to the fuselage, you can then place the
"filler box" fairing between the fuselage and the inner flaperon to match
the trailing edge of the flaperon. Same thing at the tip as you must
fabricate the trailing edge of the fiberglass tip to match the trailing edge
of the flaperon. I do agree that there are some places that dimensions would
be nice though (instead of assuming that MAM put the predrilled holes in the
right place) and if someone did want to pirate a kit all they have to do is
buy one and duplicate all the parts (I sure wouldn't do it from measurements
in a manual). I made tracings and dimensioned sketches of every part in the
kit when I built my first Rebel. I have never looked at them again, but if
wanted to build a Rebel from scratch I would be able to duplicate a Rebel
from these sketches and tracings. This will never happen though, as the kit
price is less than my time is worth to fabricate all the parts from scratch!

Keep at it, you will love the aircraft when it's done,

Murphy manuals

Posted: Fri Feb 17, 2012 5:57 pm

Terry,
I'm sure the factory would be happy to include measurements
where they would be useful, if submitted. Sometimes, they just
aren't that critical - I have seen Rebels with door frames that were
1/4" different between left & right ..... all covered by the outside
lip anyway, and worked just fine.

If you're worried about meeting the top wing skin - it usually
has to be bent to fit, in any case, so small variations can easily
be accomodated.... and things usually work out. I've flown Rebels
with ailerons that appeared to be at very different angles on the
same side - and found they still flew hands-off !! I know it's
hard to know, but many people worry a lot about things that really
aren't too important, ..... and then go and drill holes in landing
gear legs to hold fairings on !! (Not meant to offend anyone -
but sometimes a call to the factory can be very reassuring - or
help you avoid a major problem later !)

One thing I see that should be done is to make an aluminum
strip to fill in the gap between aileron sections, even if it's
just on top. This will smooth the airflow, make the ailerons more
effective, and probably give a bit more speed.....

Keep up the good work - it IS worth it !!!

Bob,

I work for an aircraft engine manufacturer and my mindset for accuracy is
a little tighter than 1/4". (In fact I'm dealing with a problem part at
work trying to figure out if a part that is .0003 inch out of tolerance
is acceptable without being reworked.) Having this mindset, I
acknowledge that I worry more than I probably should.

so, naturally, the Rebel manual, after 10 years of development,
is
more refined than the Super Rebel manual, which is only about 4
years
old, but both are improving at a faster rate, as Tech Support
gains
experience. The factory still needs positive feedback on ways to
improve things, and are most receptive. They are planning many
more
photos, and would certainly appreciate any that you could submit
that
you think would be helpful. (There are only 3 of them, and they
have
over 1,500 builders to help, some daily, as well as trying to
improve
the manuals !!) I'm sure they will thank you for the help !

WOW !!!! I'm sure everybody who rides behind those engines
you build REALLY appreciates your concerns !!! ;-)

Care and attention to detail ARE important !! :-)

Bob,

I work for an aircraft engine manufacturer and my mindset for accuracy is
a little tighter than 1/4". (In fact I'm dealing with a problem part at
work trying to figure out if a part that is .0003 inch out of tolerance
is acceptable without being reworked.) Having this mindset, I
acknowledge that I worry more than I probably should.

Terry,
I'm sure the factory would be happy to include measurements
where they would be useful, if submitted. Sometimes, they just
aren't that critical - I have seen Rebels with door frames that were
1/4" different between left & right ..... all covered by the
outside
lip anyway, and worked just fine.

If you're worried about meeting the top wing skin - it
usually
has to be bent to fit, in any case, so small variations can easily
be accomodated.... and things usually work out. I've flown Rebels
with ailerons that appeared to be at very different angles on the
same side - and found they still flew hands-off !! I know it's
hard to know, but many people worry a lot about things that really
aren't too important, ..... and then go and drill holes in landing
gear legs to hold fairings on !! (Not meant to offend anyone -
but sometimes a call to the factory can be very reassuring - or
help you avoid a major problem later !)

One thing I see that should be done is to make an aluminum
strip to fill in the gap between aileron sections, even if it's
just on top. This will smooth the airflow, make the ailerons more
effective, and probably give a bit more speed.....

Keep up the good work - it IS worth it !!!

Bob P.,

I can understand Murphy wanting to protect their property rights,
but a
few more dimensions in the manual would be nice. I am still
working on
my ailerons and an example is locating the trailing edge (AIL-28).
I can
make the 4 parts conform to the note: "Parallel and equal distance
- all
4 ailerons." but in the back of my mind I am thinking, "I sure
hope the
distance I chose mates with the trailing edge of the wing so there
is a
continuous line and not a step between the two."
