Hi William,
While building after your example drawing:
For reason of simplicity, exactly in a high stress situation (most of my landings
will be :-))managed to do away with the change-mode switch. The 3-pole reverse-unreverse
switch now operates a relay, that changes the mode. This latched
and warning labeled switch is IMHO security enough against accidental operation.
Do you have to wait for full reverse before opening the throttle? Should i think
about an indicator light that indicates the reverse end stop reached?
Regards,
Jos Okhuijsen

Hi Jos,
Yes, you do have to wait and no, I don't think you need an indicator light,
because the change to reverse is continuous and so quick, but it is
important not to be able to select reverse, or "unreverse" with the throttle
open, because when it goes through zero pitch, it will over-speed the
engine. A micro switch on the throttle box to break the circuit will do the
job.
Best wishes,
William

Subject: | W18 plate alignment problem |
While fitting the outrigger assembly to the outboard double-W18 plates
in the wing, I discovered that the fit was not very snug. It appears
that I might not have clamped the plates properly when I bonded the
W18's into the wing long time ago. The plates are not perfectly
parallel; the leading edge of the W18's are fine, but the trailing edge
is 1-2mm wider than necessary. If I bolt the outrigger assembly this
way, it may pull the W18 plates inwards and cause undue stress. The
thought of removing one of the W18 plates with a heat gun and
re-bonding did cross my mind, but that seems a bit extreme. Is there
anything wrong with shimming the gap with some aluminum sheets? Any
advice would be appreciated.

Subject: | TV crew came into my Europa workshop |
The local TV station wanted to do an interview in my Europa workshop.
The interview was not about the Europa, but actually about a mid-air
crash that occured at a nearby airport. I happened to have the only
audio recording of the aircraft communications. But they did show my
Europa kit for s good 5 seconds. Here it is:

Wow, that's too bad about the 3 three deaths involved. I can't quite tell
what the last transmission was. Can anyone tell, or have more info, other
than what is on the FAA report?
Nice job, Andrew. Maybe they'll be back, when they need a report about
experimental aircraft.
