Stu Fields
I've been sending posts that didn't show up. I've been sending e-mails to
folks that never received. I've been receiving e-mails that I couldn't
answer. We just replaced the cmos battery so we'll see if this gets thru..

vibration measurement system by
Stu Fields
I have heard that there is a down loadable application for the Iphone that
can produce 3 axis vibration measurements and store them for analysis on my
computer. EEK!! I said "How Much" and the guy said 499. I said sold!!
$500 is cheap for that capability and the guy said "No $4.99"!!! I'm...

Well there was a tip jet (70% H202) ship there with one pilot with 20 min
and a reported other pilot with a few hundred hours...
Sikorsky had a battery powered 269 on display with a duration spec of 15
min.
Safaris, Rotorways and Mosquitos and Larry Neals Butterfly wrapped up the

certified clutter out of the way, there were two helicycles flying, several
under construction showing the various aspects, a Mosquito flying all...

New coinage by
Stu Fields
I've coined a new acronym that stands for a principle often used in the
experimental helicopter community. I have named it NHFY. It stands for
None Have Failed Yet. It is a reliability measurement used by some that

Undersling and 2/rev by
Stu Fields
If an over weight pilot exceeds the recommended seat weight of his
helicopter, will this affect undersling enough to cause an increase in the
2/rev vibration??? Does increasing G forces cause an increase in 2/rev??

credibiltiy by
Stu Fields
It seems that if there are two possible causes for a helicopter accident,
the preferred one for the manufacturer is the one for which they have no
fault. That certainly is the best for them. However, lets say that a low
hour helicopter suffers a failure directly attibutable to fatigue. ...

seems to indicate an engine failure with the ship hitting power lines and
burning. Joe was an outstanding wrench and pilot. Joe did a BFR for me...

Anyone know of a transponder that can have the codes switched from a remote

access points in a connector where this could be done, or has some whiz
already done this? My helicopter likes it when I keep my hands on the...
