| Subject: | Re: Cause of Engine stoppage |
Fred, I am sure you won't need telling but it is worth emphasising that
any safety critical switch ought to be positioned or surrounded by some
sort of guard so that it cannot be inadvertently switched off in flight.
I came close to ending up in a similar fix about 15 years ago.
After a long flight I was over horizon to horizon forest in East Germany
approaching the Czech border when my bladder got to the uncomfortable
stage. I kept a pee bottle under the L. thigh support and having used
this and replaced it, I was horrified to find that all my electrical
instruments showed no signs of life. Since I was being propelled by a
914 with twin electrical pumps, this was worrying! Mind duly
concentrated, I did my usual start up checks of going anticlockwise
round the panel starting with master & alternator switches at bottom
left. Immediately apparent that both switches were off and I managed to
put them back on before the fuel in the carb bowls ran out (or so I
thought). I had clearly lassoed their rather long toggles with my
trouser bottom when lifting my left leg up to get at the pee bottle!
Having confessed to this on Matronics at the time, I was put
straight by Andy Draper who pointed out that fuel pump no 1 gets its
power upstream of the alternator switch if correctly wired so does not
stop when master & alternator switches both turned off. But it was a
good illustration of one aspect of Sod's Law that if you are going to
have a foul up it is almost bound to happen at entirely the wrong
moment!.
All best for repair of back and plane, David, GXSDJ

x-mailer: Apple Mail (2.3696.80.82.1.1)
Thats understood Matt, thanks.
Is gmail similarly affected as I get no response to that either, rogersheridan@gmail.com.
Nothing appears in the gmail spam folder.
Can you suggest an alternative?
Regards,
Roger

| Subject: | Re: What Did you do with your Europa this week 5/23-5/30 |
Last couple of weekends the weather finally cooperated and I did a couple of cross
countries and the airplane is behaving great.
Although I am certain my Europa is not the fastest it still impresses me how fast
it is. I mostly fly with friends that have LSA airplanes and, despite me cruising
at 5000 RPM, I have to depart several minutes before and still arrive several
minutes after. Impressive.
Last Monday I spent a few hours carefully dynamically balancing my prop. I though
I was OK but after checking I found the vibration to be around 0.22 ips so
worked on getting it down. I was able to achieve 0.07 ips. A short test flight
showed incredible improvement (well, could it be just mental?). But better it
is!
I got my Dynavibe Classic balancer in a garage sale and now I have a lot more friends
than I used to have before :). I made a few brackets for holding the sensors
and balancing the Rotax is easy (lots of points on the gearbox to attach
the sensors). I truly recommend that if one of these balancer can be bought using
club funds it is certainly a great addition. The difference it makes is notable
and having it handy really helps as I have found it is worthwhile doing
a check once in a while.
And last, Thanks to Ron P. for sending me a lift built by Bob B. After some minor
modifications I got it working. The only thing that was wrong was that the
standoff points that hold on to the LG shaft were a little short and would contact
the LG arm as the airplane was lifted. I made new ones a little longer and
now perfect. I made then removeable to make it easier to slide the lift under
the cowling and then insert the lift standoffs. So any thanks to Ron and Bob.
I do need to paint it though as I want it to be pretty!
Anyway, my report for the week.
Chris

Hello Chris,
Your statement above indicates that the LSA aircraft are faster than your Europa.
Is this what you meant to say?
My experience with my 80 HP Classic has shown that the only other comparable aircraft
that is faster is a Virus SW with a 100 HP engine and even then it does
not get out of sight very quickly. LOVE IT!!
Best regards
