Not so fast, boys.
In the '30s Packard developed and (I think) certified a diesel radial
aircraft engine and someone certified a counterbalanced (with a god-awful
lump opposite) a 1-blade for (at least) a Piper J-3 Cub with an A-65.
Neither set the world on fire, but there you are.
I, personally, am intrigued by Paul Lipps' investigations. A good precis of
which is available in Contact! magazine #88.5. Special issue, available.

OK Graham,

Think about the one blade for a moment. It produces thrust one side of
the airplane only, left, top, right then bottom. And that doesn't
include the asymmetric effect of angle of attack.The airframe will
oscillate in a corkscrew fashion, what a horrible prospect I can almost
feel my teeth rattling at the thought of it!
2 stroke diesel? Now that is a good idea, most efficient form of piston
engine.

Not true Raimo, it is impossible to balance out the assymetric thrust.
Vibration will be awful, so no laminar flow.
Graham
Well Graham - Germans have done many "impossible" things during
centuries...
I have seen a film about this construction (but maybe it was shit who
knows!).
Please remember, they built also the first ever diesel aircraft (Junkers
Jumo?) during -30s.
That should have been also "impossible"...

Subject: | PH-DIY first flight! |
Hi everyone!
Today, at 12:25 LT on EHHO, PH-DIY made his first flight.
Conditions were vulcanic ash, 17-22 KN head wind (straight on the runway).
According to the test pilot, the PH-DIY flies beautifully, straight and
balanced, can be flown hands-off, with a very slight tendency for left
(but this can be attributed to the asymmetric load). Only the rudder
seems to be a bit out of balance: there is always some "right rudder"
required. A trim tab would solve this. This needs some investigation.
Stals:
The stall is, clean and dirty, benign. Some buffetting, and then nothing
really happens, he just parachutes down. Absolutely no wing drop. "Like
a Cessna" according to the test pilot.
Stall clean is at approximately 50 Knots, with full flaps it is 42 knots.
Performance:
The pilot was amazed at the performance of this airplane.
Climb was 1500ft/min with 80 knots, with the power to 100% (not 115%).
Cruise was with 4200 rpm and a manifold pressure of 28 good for 120
knots IAS (the airspeed indicator has been calibrated to a maximum
deviation of 1 knots).
Conditions were somewhat turbulent, but performance data was verified in
a sequence of tries (because the pilot had some trouble to believe this
data, he tried it a few times at some distances apart to rule out local
updrafts).
We have had some temperature problems on the early ground runs, but
although the temperatures on the ground still have a tendency to rise,
during flight the temperatures were actually quite low (this was with
the cowl flap 3/4 open, I asked the pilot to leave it at this setting to
keep things simple and comparable).
Quirks:
The PH-DIY needs constant right rudder. If anyone has a good idea what
the cause can be and/or what to do about this, let us know!
In cruise, there is some down trim necessary. Trim setting is not in the
middle of the scale. I believe that this is a common thing, but I have
not yet checked the Europa forum archive for this.
Comments:
After some horror stories of Europa's that flip upside down on the
stall, we are very pleased with the benign stall characteristics of the
PH-DIY. The performance data is better than we expected, and we will of
course repeat the tests. (We have Fred Klein's wing root fairings, a
radically trimmed down and optimized cooling duct, and of course this
"can't be true" 2-blade high twist large diameter prop, so we expected
performance to be on the good side of the scale, but this is more than
we accounted for).
Well, tomorrow we will give the PH-DIY a thorough check, so if weather
cooperates we will saterday fly ourselves (first with an instructor of
course).

Many congratulations Frans,
The plane looks beautiful too. For the records, can you please tell me the
name of the test pilot, the final empty weight and the estimated build
hours.
The minor adjustments needed seem pretty normal to me. Down elevator trim
in the cruise is completely normal.

Final test pilot was Robbie Snghal, the empty weight is 421 Kg's,
build hours unknown (really!).

OK! So, then only the right rudder thing is something to work on.

Frans and Illona: congratulations on the wonderful job the two of you did!
Good to hear all went beyond expectations with good stall-speeds and behavior!
Thanks for giving me a heads-up yesterday, unfortunately I had business-commitments
preventing me to witness this wonderful moment. For sure this must be a day
you won't ever forget.
I will be there on Saturday for sure, we'll talk further then.

Hi everyone!
Today, at 12:25 LT on EHHO, PH-DIY made his first flight.
Conditions were vulcanic ash, 17-22 KN head wind (straight on the runway).
According to the test pilot, the PH-DIY flies beautifully, straight and
balanced, can be flown hands-off, with a very slight tendency for left
(but this can be attributed to the asymmetric load). Only the rudder
seems to be a bit out of balance: there is always some "right rudder"
required. A trim tab would solve this. This needs some investigation.
Stals:
The stall is, clean and dirty, benign. Some buffetting, and then nothing
really happens, he just parachutes down. Absolutely no wing drop. "Like
a Cessna" according to the test pilot.
Stall clean is at approximately 50 Knots, with full flaps it is 42 knots.
Performance:
The pilot was amazed at the performance of this airplane.
Climb was 1500ft/min with 80 knots, with the power to 100% (not 115%).
Cruise was with 4200 rpm and a manifold pressure of 28 good for 120
knots IAS (the airspeed indicator has been calibrated to a maximum
deviation of 1 knots).
Conditions were somewhat turbulent, but performance data was verified in
a sequence of tries (because the pilot had some trouble to believe this
data, =C2-he tried it a few times at some distances apart to rule out loc
al
updrafts).
We have had some temperature problems on the early ground runs, but
although the temperatures on the ground still have a tendency to rise,
during flight the temperatures were actually quite low (this was with
the cowl flap 3/4 open, I asked the pilot to leave it at this setting to
keep things simple and comparable).
Quirks:
The PH-DIY needs constant right rudder. If anyone has a good idea what
the cause can be and/or what to do about this, let us know!
In cruise, there is some down trim necessary. Trim setting is not in the
middle of the scale. I believe that this is a common thing, but I have
not yet checked the Europa forum archive for this.
Comments:
After some horror stories of Europa's that flip upside down on the
stall, we are very pleased with the benign stall characteristics of the
PH-DIY. The performance data is better than we expected, and we will of
course repeat the tests. (We have Fred Klein's wing root fairings, a
radically trimmed down and optimized cooling duct, and of course this
"can't be true" 2-blade high twist large diameter prop, so we expected
performance to be on the good side of the scale, but this is more than
we accounted for).
Well, tomorrow we will give the PH-DIY a thorough check, so if weather
cooperates we will saterday fly ourselves (first with an instructor of
course).
Pictures of the first flight can be found on our website at

Subject: | Mod 67 mouldings |
Has anyone in US done the cockpit width increase mod 67 and have the used port
and starboard mouldings available?
Thanks,

Congratulations Frans
Anyone completing a Europa deserves a medal in my opinion.
Great word from down under.
