| Subject: | Re: motorglider V-speeds and registration |
Dave,
We followed Dave Anderson's lead and registered our Europa as an Airplane / Motorglider.
We did that by adding a statement to the Program Letter that says it's
a glider with long wings fitted and an airplane with short wings fitted.
Our Op Lims that the FAA gave us has that same statement in it. Our Airworthiness
Certificate also says Airplane / Motorglider.
Your pilot license shows your ratings, mine says ASEL; Glider; Instrument Airplane.
FAR Part 1 defines an "airplane as engine driven, fixed wing aircraft" and
defines "glider as ..whose free flight does not depend principally on an engine".
So when my Europa is configured with the short wings, it is an airplane
and I use my ASEL. When it is fitted with the long wings it is a glider and
I use my Glider Rating.
In a similar manner, the FAR's require that I have a current Medical Cert when
I exercise my ASEL privileges. I do not have to have a Medical Cert when I exercise
my Glider privileges.
There is also a note in AC21.17-2A para 7b that states that for a motorglider you
must show that the calculation of max weight to wing span squared must not
exceed .62 lb/ft squared. I calculated this for a short wing XS and I got 1.85;
for the original glider wings (42.6 ft wing span) I got .77; for the current
wings (47.25 ft wing span) I got .61. So you must have the new style wing
tips to be legal.
In reality none of this matters UNLESS you are ramp checked or involved in an accident,
incident or other action that gets the FAA's attention.
Bud, Thank you for making the Motorglider POH available. I didn't know it existed
(even been told by E04 that it didn't!). This makes operation of the motorglider
much safer!
Paul, since my license says Instrument Airplane, I can't operate as a motorglider
IFR.

Terry,
You wrote, "If I lose my airplane medical and continue flying as a self launched
glider pilot, can I then fly the long wing Europa AIRPLANE legally?"
The answer is NO. To operate without a medical your Europa must be registered
as a motorglider and have the long wings fitted.
A pilot with ASEL (and no self launch glider rating) can only operate a Europa
with the long wings fitted if the Op Lim does not specify the two configurations.
But then he must have a Medical.
Certainly the motorglider configuration is a nice airplane with the engine running
- John Hurst preferred that for long cross country flights!

Hi Raimo,
If you install a 7.00-6, 6 ply tire, you should have no problem with
contact between the tire and the caliper.
Cheers, John
3) why I have some slightly contact with tire and brake calliber?
Is it only my problem? If I change to the size 7.00-6,
that contact is away - am I right?

One question: When you went thru your registration process, did you
have the long wings in hand for inspection, or did you merely reference
the Europa written material/pictures to support your application for
dual categories?

Andy Draper said the following in a letter he wrote me on 15th August.
" The Woodcomp scimitar blades are acceptable, however there is an issue
with the diameter. The maximum diameter propeller accepted on the Europa XS
monowheel is 64" (1625mm). If you wished to fit a larger diameter propeller, you
will need to show compliance with CS-VLA925. Amongst other things to check,
the ground clearance from the propeller tip with the aircraft fully loaded, in
a level attitude and with a flat tyre must be at least 230mm."
Andy therefore seems to think you do have to have a minimum of 230mm
clearance with a deflated tyre. However, I agree with your interpretation of the
rules, and I think he could be persuaded that with a deflated tyre the rules
only require "positive clearance".

"(a) Ground clearance. There must be a clearance of at least 180 mm (for

If my interpretation is right there have to be two checks made. You first
load the aircraft up to its maximum weight and the clearance has to be in
excess of 230mm, then you deflate the tyre and there should then be what they
describe as "positive clearance" .
Having said this my understanding is that most Classic Europas would fail
the VLA test even with the 1575 blade fitted (ie: the Warp Drive). However the
ruling is not retrospective so should not affect existing approved
installatons.
Apparently the XS monos are not similarly affected because the XS engine
mount raises the propeller by about 1.5" (compared to the mono. Consequently the
1625mm prop can be approved.
None of which is any help to me - it seems the Woodcomp is a non starter.

Hi Jos
You can blame me, at least in part, for the Golf cart tyre supplied in the
early kits.
Many years ago I happened to be at Kirkbymoorside when Ivan was trying to
contain escalating costs during development of the first series of kits. He
was looking into the use of alternative tyres he asked me If thought
customers would find the golf cart tyres acceptable as they were
significantly less expensive than true aircraft tyres. I was going through
one of my phases of thinking that most aircraft parts had a large element of
added cost over exactly equivalent commercial parts. So I said that if they
were Ok for size ,loading, speed etc then I would by OK with the alternative
tyre.
I note your comments about the Europa being a well tested product is
completely correct but bear in mind that since the take over by EMIL some
years ago virtually all development was stopped and since then all the
experience that has been gained has been by owner builders and flyers like
you and John.
The Europa is in many ways an "Experimental" aircraft and development is
necessary or it will not evolve as it should and could just fade away. So
please do not stick to the view that the design is perfect and if it's not
in the build manual it's wrong.
Best regards
Tim

I always said (to Ivan many times) the short wings were Too short. He
always says it would spoil the handling to lengthen them but then he is
obsessed with scarumbatics. Scared me a few times!
The rate of climb of the motor glider is much better than the short
wing. I only flew it once but when I finally got the speed on full power
climb out down to 70 kts the angle was so steep it was a while before I
dared to turn! That was in G-ODTI (go dotty?) with the foam wings, which
are still lying in the hangar I think,

The way I read that is that the sentence requiring you to deflate the
tyre
only applies to "for each aeroplane with conventional landing gear
struts
using fluid or mechanical means for absorbing landing shocks". Unless
there
are more words elsewhere in the regulation that are not in this email

Hi Tim,
You are right, in that further development of this airplane should be possible
and should happen. Exactly on this forum are also great solutions and changes
made available. My plane is not standard at all. What i do object against is "advice"
without even the most basic form of substantiating the content. It does
not matter if it is about the color of the interior, but if it involves security
or flying properties some self discipline is called for. Advising to remove
throttle springs was a fine example, changing tire size is another one.
I don't think the golf cart tires were a very good idea, although some of them
are still around. Apart of the difference in price, there is probably also a difference
in the narrowness of the specification. Raimo's tire is 8 years old
on top of that. Tires do have a limited shelf life. Time to change for a real
airplane tire! (of the right size)

Thanks John,
The problem is that we have a Classic Europa which is 1.5" closer to the ground
and it seems that all current propellers (including the approved 1575 mm dia
ones) would not pass the VLA requirements.
I am going to make some measurements tomorrow to check this is the case.
The only way it seems that we could fit the Wood-comp prop would be to upgrade
the front end of the AC to the XS specs - it simply wouldn't be cost effective
and probably cost more than the prop.
The only reason we are seriously considering fitting a VP prop is because of Mod
74 - there seems to be no point in doing this without incorporating Mod 52 (weight
increase mod).
The only other serious option is the air master setup which is the one favored
by the PFA. The Arplast from what I hear is not particularly reliable due to their
using an underpowered motor.
I was hoping that with William Mills using a Scimitar blade prop on his Classic
it would be relatively straight forward but Woodcomp themselves say this particular
prop is 1650mm and that they never made anything smaller.

Pete,
The wording quoted in my email is precisely as per the VLA manual. There is more
on the subject further in the chapter but not relevant to the clearance issue.
None the less I am inclined to agree that this would be the official interpretation
though I would be tempted to argue the case with the PFA. IMHO the actual
wording is perfectly clear and logical when you think about it (ie: it allows
for the possibility of a puncture). There seems to be no merit in insisting that
there is at least 230mm with the tyre deflated - what would that achieve?
When I have made some measurements (which I will do tomorrow) I will know if there
is any chance of putting forward a valid argument.
One further thought is that when the aircraft about to off (ie: level) the undercarriage
is supporting very little load as this is taken up by the wings. In
the landing configuration the prop is nowhere near the ground (ie: stick well
back). I wouldn't expect the PFA to buy that argument though.

Carl,
Responding to two of your points:
I should think that the prop to ground clearance would be at a minimum on a heavy
arrival when the main gear tyre and suspension is compressed and, possibly,
the tail is still in the air.
The paperwork that came with my scimitar bladed SR3000 states it is 1625mm in diameter
(not 1650). Perhaps the paperwork is wrong. If it is, do I have to saw
1/2" of each tip?

Subject: Quandary
Say,
I thought I'd share a story with you - you, who have the original
trailer.....
It's been so long in the build, and the trailer was at home, I
thought to see
how well the stabs sat in it, with the fuselage aboard - perhaps even a
photo
opportunity.
On they went, slick as a whistle.
However, on retrieving the pair, the fascinating little black plug
that ends the
tube holding them was missing. Can you guess where it hides? Yes, in the
bottom of
the stab hole.
Any suggestions as to the recovery of the little black plug would be
gratefully
received here. In the meantime, take all rational measures to prevent
another loss.
Cheers, ferg
Wiring, wiring
Hello,
....to those of you who may have read of the original 'Quandary'
(and/or have a Classic mono trailer). Above, a review of the trouble.
First a thank you to the various creative suggestions sent to me in
reply. Some I tried, some were not possible. The fact that the stopper
jammed beyond the outer bearing precluded TNT, the vacuum cleaner and sundry
other modi operandi.
I thought you might want a success report.
I had produced a 3/16" hole in the tip of the stab, concentric with
the 1-1/2" stab axle hole. Its purpose was to permit wiring an AA battery
inside the end and wires to a bright LED which curved around the top of the
tip to illuminate the vertical fin - airline-wise. I should have mentioned
this.
A word in praise of British Telecom is in order. They came to a
sultry corner of Devon several (many) years ago and clipped about half a
mile of beautiful 4mm Copperweld wire from adjacent poles, and tossed it
into a 'kip' (movable garbage bin).
Happening by, I casually asked whether it was going straight to Hades in a
handcart and the reply gave me an immense coil of it. How it got to
Burlington, Canada is a boring story, but it sat grinding its teeth in my
basement.
That is, until I realized that 4mm goes into 3/16" very handily. I
cut a metre-long piece, spent some time straightening it and slid it down
the little hole toward the cowardly stopper. When it stopped against the
miscreant, I bopped it with my little hammer and that rotated the stopper to
a diametric stance across the outer bearing.
Retrieving the wire, I then applied the electrical pliers to bend a sharp
180 in the end, and then clipped that to a nasty point with the nippers.
With Jenny holding the flashlight (torch) above the inboard end of
the stab axle hole I cannily slid the hook past the wall of the stopper,
rotated 90 degrees, yorked upward to set the hook and then wrenched the
@#$%^& free. It bent obediently to the task and actually flew across the
room with hardly a whimper.
By this time the trailer, having been left to its fate outdoors, had
collected several inches of rain down the spout and required suction,
alcohol and used motor oil to stop the incipient rust. The stopper was
applied and I washed my hands.
Thus endeth the lesson.
Cheers, Ferg

Mark,
On a mono wheel Europa if you land in a "level" attitude you are heading for trouble
anyway. The ideal attitude is tail and main wheel simultaneously though
tail first is acceptable.
I emailed Andy on Friday and here is part of his reply
"The largest diameter prop that is accepted for use on a mono-wheel Europa with
the Classic engine installation is 62" (1575mm). The XS engine installation
places the engine 1.5" higher and therefore a 65" (1650mm) diameter is accepted,
although generally the 64" (1625mm) diameter is used.
On a recent check that I did on ground clearance, if the VLA requirements were
adhered to, then the Classic mono would be limited to about a 56" diameter! "
I also spoke to Conrad Beale and he tells me that the standard Europa Wood-comp
is 1625mm and the Scimitar Wood-Comp is 1650mm. Wood-comp say they only use one
mould for each prop and that the sizes have always been the same.
It doesn't really matter if your Scimitar prop is 1625 or 1650 because (presumably)
there is more than adequate clearance with the tri-gear setup.
It would be worth knowing what the measured diameter of your prop is - hopefully
its the same as the paperwork.
What concerns me is that Woodcomp says the Scimitar prop is 1650 mm (65") but your
paperwork (and Williams) says it is 1600 mm (63").
If you don't believe me heres the link to Woodcomps specs.

This is probably a better link to the Woodcomp specs.

Carl,
The people with tape measures don't care about it being better to land tail down.
If it's possible to plant the thing heavily on the mainwheel in a level attitude
then that's what it has to be able to cope with (from a prop clearance point
of view).
Personally, I don't believe William's prop was 63" in diameter. From memory, he
(verbally) told me: "I asked for a 63 inch prop, and that's what I believe I
got". I don't know if he ever measured the diameter.
Mark

Carl,
The Woodcomp specs are not always correct. On paper my prop is 1750, but the
actual diameter is 1720. Also, the specified weight is less than the actual.

Say,
I thought I'd share a story with you - you, who have the original
trailer.....
It's been so long in the build, and the trailer was at home, I
thought to see
how well the stabs sat in it, with the fuselage aboard - perhaps even a
photo
opportunity.
On they went, slick as a whistle.
However, on retrieving the pair, the fascinating little black plug
that ends the
tube holding them was missing. Can you guess where it hides? Yes, in the
bottom of
the stab hole.
Any suggestions as to the recovery of the little black plug would be
gratefully
received here. In the meantime, take all rational measures to prevent
another loss.
Cheers, ferg
Wiring, wiring
Hello,
....to those of you who may have read of the original 'Quandary'
(and/or have a Classic mono trailer). Above, a review of the trouble.
First a thank you to the various creative suggestions sent to me in
reply. Some I tried, some were not possible. The fact that the stopper
jammed beyond the outer bearing precluded TNT, the vacuum cleaner and sundry
other modi operandi.
I thought you might want a success report.
I had produced a 3/16" hole in the tip of the stab, concentric with
the 1-1/2" stab axle hole. Its purpose was to permit wiring an AA battery
inside the end and wires to a bright LED which curved around the top of the
tip to illuminate the vertical fin - airline-wise. I should have mentioned
this.
A word in praise of British Telecom is in order. They came to a
sultry corner of Devon several (many) years ago and clipped about half a
mile of beautiful 4mm Copperweld wire from adjacent poles, and tossed it
into a 'kip' (movable garbage bin).
Happening by, I casually asked whether it was going straight to Hades in a
handcart and the reply gave me an immense coil of it. How it got to
Burlington, Canada is a boring story, but it sat grinding its teeth in my
basement.
That is, until I realized that 4mm goes into 3/16" very handily. I
cut a metre-long piece, spent some time straightening it and slid it down
the little hole toward the cowardly stopper. When it stopped against the
miscreant, I bopped it with my little hammer and that rotated the stopper to
a diametric stance across the outer bearing.
Retrieving the wire, I then applied the electrical pliers to bend a sharp
180 in the end, and then clipped that to a nasty point with the nippers.
With Jenny holding the flashlight (torch) above the inboard end of
the stab axle hole I cannily slid the hook past the wall of the stopper,
rotated 90 degrees, yorked upward to set the hook and then wrenched the
@#$%^& free. It bent obediently to the task and actually flew across the
room with hardly a whimper.
By this time the trailer, having been left to its fate outdoors, had
collected several inches of rain down the spout and required suction,
alcohol and used motor oil to stop the incipient rust. The stopper was
applied and I washed my hands.
Thus endeth the lesson.
Cheers, Ferg

| Subject: | Trigear Max Prop Size |
Seeing all this discussion about the size of prop allowable on Mono's
prompts me to ask if anyone knows
what the largest prop for the Tri is 62".... 64"....66"?? given the
different static angles on the ground etc
thanks

Hi John,
I don't know if this is a silly idea or not, but I remember a physics
experiment once where we emptied 5 gallon jugs. One jug we set up a
swirl action and compared the time to the jug that just "glugged
away"... the swirling action was much faster.
So, I was wondering if on your inlet if you could encourage the air to
spin a little if you would stop the pressure wave, and possibly get
more air into the inlet.
Hope this makes sense.
Paul

| Subject: | Trigear Max Prop Size |
At least 70" if you make the necessary mod to the nose gear . I had a new
spindle machined out of the same material as the original, which is 50mm
longer. It increases the nose-up attitude on the ground by 1.6 degrees, and
there is no noticable change in handling.

> Time to change for a real airplane tire! (of the right size)
Jos,
Europa supplied me with a CARLISLE 800 x 6 x 4 ply (Golf Buggy tyre)
On advice from others who have used both, I purchased a CONDOR 700 x 6 x 8
ply.Aircraft tyre (Fits Piper Aztec)
With both inflated to the same pressure on the same wheel they measure
Europa CARLISLE Diameter 440 mm Width 185 mm (rubs on brake calliper)
Aircraft CONDOR Diameter 457 mm Width 165 mm (comfortably clears
brake calliper by 10mm)
My question is, WHAT IS THE RIGHT SIZE ? How can a 7.00" tyre be bigger in
diameter than an 8.00" one? and No, I haven't made any mistakes with the
figures above.

Kingsley in Oz
