Hey Guys, as long as I am into this eastern block stuff, I am using one of
their heated pitot heads and tubes. It will stick out of the left wing about
30 inches. It has the static holes as well as the pitot port. It will look
like the old C-195 set up. They are common on almost all of the eastern
block aircraft. The heaters are 24 volt and since I am putting a 24 volt
system in my SR it will work fine. That said, I have the Murphy supplied
head for sale.
By the way, I have a good deal available on a first overhauled 400 hp M14P
with a new engine warranty. It will be complete with electric start,
Sytronics 50 amp alternator, western prop flange, western fluid fittings,
dress kit, spares kit and tool kit. The overhaul and conversion to 400 hp
was done at the manufacturer.

I purchased the Murphy pitot, but can't see how the static can work
properly
when it just samples the air around the pitot head. Also, it is not
heated,
of course, and is susceptible to damage. So I bought a used C150
pitot for
$150 Cdn and plan to locate it more or less where Cessna does, with
static
vents on each side of the rear fuselage. However, no reports on how
well it
works yet, since I'm only about 50% complete.
Regards,
Al

I used the mam supplied pitot/static tube which is mounted on the
left
wing
at the strut attach point. The lines run down the strut and into the
cockpit. The pitot tube sticks out about a foot in front of the
wing. I
questioned whether or not this was the best thing to do. Well it is
pure
Murphy. I think also that it may take a beeting being right at head
height
as you walk in front of the wing. Other builders have mounted a
pitot/static
under the wing which is probably a better idea.
As for your idea of getting it into cleaan air, I can't realy
comment on
how
far away from the fuselodge it should be.
Good Luck
Murray

G'day Fellow Murphy Mob !
Got a strategic question for you all.
Our Airspeed pitot / static pipe is currently hanging under the R/H
wing, just outboard of the strut attach point
It hangs down about 10" below the skin & I made it for the grand
cost of
about $1 ....
It works very well ..... but the problem is, people keep walking
into it
.... and I fear one day. some geek will take his or her eye out on
it &
sue me :-(
So I figured I'd move it to the leading edge on the L/H wing ...
where
the stall speed alarm flap/lever/gizmo sticks out (I never use it
anyway) ..... but a fellow aviator insists that it must stick out
about
3 feet to get into clean air !?!
I was going to make it about 8 to 10 inches long ..... but now I'm
worried that this might not work.
Can I have a show of "Where we put ours" & what design it is so we
can
do it right the first time (or second time actually :-)
Thanks all !
