Roger---
It is with deep sadness that I report to you and all Southern Calif. Aero
Team members that Steve Geraghty passed away from this earth this morning
(Wednesday) at approximately 5:45 a.m. He was returning Tuesday morning to
San Jose from Idaho and suffered a life threatening viral infection, the
cause which has not yet been determined.

Steve was a strong member and supporter of the Oakland Cloud Dusters, SCAT,
NFFS, AMA and numerous FAI free flight team programs and world
championships. He most recently assisted me and Bill Vanderbeek in running
the Northern California Free Flight Championships earlier this month.

He leaves behind his wife Sharyn, stepson Jason, his sons Gerry and Jim, and
a sister in Southern California.

SCAT readers can contact me through electronic mail for further information
as it becomes available.

Sincerely,	Fred Terzian	This email address is being protected from spambots. You need JavaScript enabled to view it.

Today I came across intersting article in 'Scientific American'.
I am sure that Scat E News readers will find new insights into the developing
world of micro aeronautics and insect flight,  will we see flapping wing UAVs
?. Check it out.

I was wondering if others have been having problems with recent batches 
of Nelson plugs seating firmly and sealing in their engines.  The torque
when tightening the plugs feel mushy for the last 1/4 turn and bubbles 
are evident around the base of the plug when leak checking the 
installation.  I was experiencing this problem quite severely with my KC 
0.060 and was told that my head insert needed to be tapped deeper. I 
borrowed a 11/33 X 32 bottoming tap from Bob  Johannes and tapped the
hole as deep as possible.  The plugs would still not seat properly.  The 
plugs appeared to be about 1/2 turn from seating when finger tight as 
viewed from the combustion chamber end.  After a complete comparison of
dimensions of old plugs which would seat and new plugs which wouldn't I
concluded that there was no reason for the condition.

The only difference I noted was that upper most thread on the new plugs
(closest to the hex) seamed to be poorly formed and blended into the 
next thread.  It appears to be a problem with roll forming.  About 180 
degrees of the upper thread was removed with a needle file and the plug
seated and sealed very nicely.

Has any one else experienced this problem and come to the same 
conclusion.  I have ordered a 11/32 X 32 die and will chase the threads 
on all Nelson plugs.

I wish to let Herm know that I have read everything he has susbmitted to SCAT 
Electronic News.  It is just that I had a hard time trying to understand what 
he said.   Perhaps if he wrote in Pig Latin....

Hello Fellow Modellers,

	Can any of you inform me as to what issue of Model Airplane News the
article for the Satellite 800 ran in?  I believe it was about 1960.  I am
trying to acquire a copy of the article and your assistance is greatly
appreciated!  -- Iain  This email address is being protected from spambots. You need JavaScript enabled to view it.
