Aviation Forum / General / Homebuilt / June 2008

I apologize if this is too far off topic as this is not a homebuilt
for sure.  Useful for education.  It is interesting in the design and
efficiency of operation.  I am surprised that it has not made the
commercial market place with our increasing fuel costs.

Well it has happened.  Local 100LL is $5.60/ gal and is not expected to
decrease.  Is there anyone out there using Supreme MoGas in a Lycoming 0320
with 8.5:1 compression?  If so what ignition timing changes were needed if
any?

JIm Weir,
I noted your article in the current issue of KP on LEDs.
I have purchased a small quanity of these.  hard to find as they were

I was working on one wing when the other wing (and I'm guessing)
vibrated of the supports onto the concrete. It broke the end rib which

Can not possibly afford a hanger and can not find a shelter so my plane will
have to sit out. Is a fabric covered plane an absolute no-no? What can be
done?

Having attended Oshkosh for the last 35 years without fail, Jim Weir's
recent message that he'd have to miss this one due to rising fuel
costs, was an item of conversation last Sunday at our Irregularly
Scheduled, Often Delayed, Homebuilder Koffee Klatch here in northern

Samsung SC-MX10-XAA.  Type that into Google, they'll show you a
picture of it.  But it is smaller than it looks -- it's about the size
of a small Russet potato... about 5" long by 2.5" in diameter.
Street price is about $180 (as of May 2008)

This week's Mystery Topic appears to be Valve Train Geometry, with a
total of four messages since Monday, including one today.
It's really pretty simple -- you're actuating a pivoted lever with a
push-rod.  The goal is to do so with the least amount of wasted
