Dear Graham,
that was a good one. But is was not reality this time: when I took power
off during a long and high final, it was really off.
So it was a glide abroach but only because I wanted so (and the engine
was idling).

Could be Trev. One carb on fixed power and the other on variable
therefore only smooth at one power setting. Must have been a glide
approach when you got home Raimo?

Yes I am Tim=99s daughter, Hannah, and my second guess is;
Was the Airmaster Auto/Man switch left on Man for the Take-off?

Hanna,
are you sure you are Hanna or in fact Tim, Hanna=C2=B4s dad (who is
going to try to win desperately the shipment from Finland) ? ;)
If you really are Hanna; you may try 2nd time, because you are a
pilot=C2=B4s daughter.
Please read my first mail once again carefully: I wrote
=9CSoon until well over the ground at altitude +500 feet with
full power and 2nd fuel pump still on ... =9C
Notice also, these words below are really essential info, something
maybe to do with prop/pwr =93settings:
=9CThose minutes were long: I put my prob (Airmaster CS) to
manual and drived it from fine to coarse, tried all the power settings
and also a 2nd fuel filter. Finally I noticed that when prop was in a
climb mode (in my case 5400 rpm /Rotax 912S) and MAP around 20 inches I
got quite a comfortable flying mode and I headed straight home.
=9C

All,
One of you is now really close, physically say 50 mm /2" inches.

Raimo,
Two thoughts.
Fuel starvation with the fuel pumps not turned on for take off?

I have got plenty of good guesses via list and also direct.
Some of you have hoped I will not publish them with their names
and do not worry I wont=C2=B4t.
Graham =93 I /we got an empty message from you =93
please retype it =93 I am sure it will be a good info.
One of you have guessed the problem was because a broken de-icing
rubber in the prop blade. That=C2=B4s good but unfortunately my Europa
is so far still missing de-icing systems totally. They would be soon
very useful in Finland.
***
No one has so far found a reason for my vibra.
So there are still a possibility to get an Xmas packet from
Finland.
I quarantee the shipment will be worth of making a good guess.
***
Tips:
- the reason was off /on or black /white =93type and very
easy to repair; it was fixed in seconds.
- when finally found it was not invisible at all.
Go On!

I have hope-so a nice riddle for you.
Maybe all the answers are useful =93 let=C2=B4s collect them
all:
***
Yesterday I took off from a very remote /small /windy (90 degrees
12 knots and gusting MUCH) grass strip. Soon until well over the ground
at altitude +500 feet with full power and 2nd fuel pump still on and
gears up I felt suddenly let us say medium or more shake and vibration.
My immediate reaction was to go around and land immediately but
abandoned because wind was so furious and I felt I cannot do that (a
succesful landing).
I decided to try to fly to the next possible sensible airfield
EFHV which was 10 minutes apart.
Those minutes were long: I put my prob (Airmaster CS) to manual
and drived it from fine to coarse, tried all the power settings and also
a 2nd fuel filter. Finally I noticed that when prop was in a climb mode
(in my case 5400 rpm /Rotax 912S) and MAP around 20 inches I got quite a
comfortable flying mode and I headed straight home. My airspeed was w
that selection about 110 knots but because of a strong headwind GS was
only about 70 knots (wanted to be clearly over the ground at 3000 ft
because it was well over sunset and totally dark, yesterday we got
sunset around 1600 Zulutime and time was well over 1630 when flying).
So, I pushed home one looooong hour. All the aerodynamics were
well. I was a bit worried my engine will separate or so. When trying to
push more pwr it was more vibra and when trying to pull less pwr same. I
Followed a main highway and decided to land there if feeling so. Cars
there with lights are almost like a lighted runway...
Finally landing to the EFTP flawlesly.
***
Today we had a FHGP (Family Hangar Grill Party). I tried to check
my plane as well as I can. I found something. Very small evidence but
something anyway. I tried to fix it and had a test run. I elected to go
to fly =93 hey I am a test pilot who else =93 and She was
better than ever!
I managed to do 2 touches and goes when C172 did one with same
runway.
140 knots during downwind makes me always happy.
***
So =93 dear Ladies and Gentlemen =93 what was wrong?
It would be nice and very life-useful to hear your opinions or
guesses what was wrong.
***
The Rules: one single guess per person, please.
The Prize: The Best Guess will get a Very Special Xmas Present
---From Finland!
***
I will let you know a solution after a week =93 be patient.
Have a nice weekend and
Cheers, Raimo Toivio
