The Murphy Builders Site

hi all

just got isometrics of elite tail from Murphy, holly cow there is
allot of
metal in the tail compared to a rebel, based on this i would think
its a
really bad idea of putting an 0-360 into a rebel, as example the
rudder has
6 brackets to hold it on, in pairs of 2's, and attach points to
fuselage are
allot bigger than the rebel as well

G'day Walter

Have you looked at the performance increase you get from
fitting an
electronic ignition - such as L.S.E. or a P-Mag ........ ?

Bigger / fatter spark gives a noticeable boost to performance !
(and
better fuel consumption as well

Aren't there some Rebels already using the 0360? Yes, from what
I
understand, too, the tail area may be the weak point on the Rebel.
And I
also understand the tail may be overbuilt for the Elite. But what
exactly does more hp do to the tail? If there is a problem,
wouldn't it
show up with some cracking somewhere. I know we've had a few mods
to the
tail now, so it should be stronger than we've had before. Of
course, I
would not want to risk sudden failure of the rudder coming off or
something like that, but is that likely?

In my case, I only want the 0360 to get more hp at high altitude
lakes
(5000 feet+), and to climb over some higher mountains. I can tell
you
from experience, my 0320 is not producing a lot of climb anymore
at 8000
feet. If I was on wheels only, I'd be happy with a 912S or 0235.

I guess another option would be to turbocharge the 0320, but as
I
understand it, that would weigh more and cost more than an 0360,
so
what's the point.

Hi Walter if all you want is to get out of those high
altitude lakes just
add a nitrous oxide system :)

I've never really looked into the nitrous systems, but yes,
that's perhaps something for me to explore. I know Al P. has it
in his Moose. My 0320 is just a regular narrow deck variety, and
not sure if it could handle the extra boost. I would hate to blow
a jug or rod in hostile alpine terrain just after take-off. And
what revs would it drive my fixed pitch prop on take-off? Anyway,
more food for thought. Thanks Drew.

WRT tail strength as an issue, there is at least the
general thing of more HP
translating to more overall work put on the airframe.
Pilots will be tempted
to go faster, carry more weight, not just climb higher
or fly at higher
altitude. Faster speeds especially at gross weight
translates to more
structural loads, and the tail of course is what
counters pitching moment.
OTOH, if one treats the greater HP with good sense,
i.e., just greater climb,
and the weight is equal or less, and you aren't also
needing to put in more
weight in fuel or counterweights in tail, then I can't
see a problem. That
opinion is worth what you paid for it of course. :)

Walter -- you mention Snow Cap lake. I'm curious of
anyone here what the
highest elevation lake anyone has taken off from in a
Rebel (with whatever
weight stated approximately). Anyone >5 or 6k?

Maybe a paxton blower off a '69 Mustang! That way you can keep the HP at
altitiude! What I like about the GSO-480's in the UTVA's...always 340HP no
matter the temp or altitude (to a point)

Al....have you punched that little red button yet???!!!! )
