Subject: | Mod 7 flight ready |
Dave,
I can confirm the current Vne for the UK MG is still 127 knots
indicated, at a max weight of 1370 lb with C of G limits 60.4" to 62.5". I
am still awaiting for all the other limits to be formally specified by the
LAA as part of the Certification process along with the issue of the Permit
to Fly. Europa issued a modified ASI glass with revised colour bandings
that we used during the spinning trial for G-CBHI, but I have not had it
confirmed these are the final approved figures. I may know a bit more when
the LAA return to work next week as I am trying to get an agreed Flight Test
schedule issued.
Best Regards
Ian Cook

Subject: Europa-List: Mod 7 flight ready
Again, I'm not sure how many are interested in this, but here is another
update:
The last issue I had with the prep for flight was the pip pin engaging with
the bellville washer. I installed the pin and it seemed to be barely
engaging the washer, if at all. I could not pull it back. I planned to drill
an inspection hole in the wing root faring to put the video snake in to see
if the pin head is coming through the fatter spar. I worked on it today and
discovered that I can look through the inspection hole to the port fuel tank
outlet and see the end of the pip pin. It was fully engaged. I was able to
work it back and determine the shim washers to account for the play. Two
thick washers did the trick.
The airplane is now ready for flight. If the weather cooperates, tomorrow
will be first flight. I will post the results of that flight.
The gut check is that the wing root fairings are mating with the fuselage as
they were before - within reasonable limits. It does feel good to have the
stronger structure now.
Does anyone know what the speed are supposed to be on the modified airplane?
I have 127 knots for Vne from the past, but the website shows 165 knots on
the specs - the same as the short wing airplane. I also have 97 knots for
maneuvering speed and the top of the green arc. With that speed, normal
cruise will be well into the yellow arc. I see around 110 knots IAS in
normal cruise. That is at about 28 inches. Rotax 914.

Ian, did Europa have to change the hex bolts on CS08, both Dave and I feel the
need to do so. As you know it is a little easier for Dave with EAA than for us.
If the factory felt the need the amendment to Mod 78 would be the simplest route.

Subject: | Re: RotaxEngines-List: CarbMate |
Hi John,
I use a balancing tool similar to the Carb Mate to do my synchronizing.
First, only adjust one side, never both sides. All you are trying to do is get
one side to match the other. If you try to adjust both sides youll be chasing
it all day long.
Pick a side to adjust and make a small adjustment on the ferrule, really doesnt
matter which way, all you want to see is which way the Carb Mate changes. If
it improves, that's the way you want to adjust to balance. If the Carb Mate
goes the wrong way, you want to adjust the ferrule in the other direction. Then
continue to make adjustments till you get the Carb Mate centered at highest
resolution.
Its really quite easy once you get the hang of it.
Rotax-Owner.com has a good video review of the Carb Mate which includes a demonstration
on its use. You should check it out. If you are a member of Rotax-Owner.com
there are other excellent, detailed, videos available on carb balancing
the 912/914. If you arent a member of Rotax-Owner.com I highly recommend joining
to gain access to all their other videos and to their informational e-mailing.

I used a Carb Mate synchronizer once and found I was fumbling around a lot to get
the carbs balanced.
If, for examle, the LED light is offset to the right, do you loosen , or tighten
the cable feed to that right side carb? Or do either to the left side?
Instructions didn't provide any clues.

Subject: | Re: RotaxEngines-List: CarbMate |
Thank you, Bob, for your iinformation. I appreciate it. I am in an RV-12
with 190 hours on it now...many minor items have come up but so far nothing
major which I hope continues because if you need to get at the starter or
other major things the entire engine would have to be pulled...a real
pain...the RV-12 with the Rotax 912uls is pretty crowded.
Again, thank you
John

My Europa is now standing on its own three wheels so I have no further
use for the support frame. It is a large long triangular construction
with braked castoring wheels on each corner. Suitable for mono or tri
gear & available for a contribution to 'Help fo Heroes' charity only.
Obviously for collection but does fit on a roof rack. I live in north
Essex near Saffron Walden. Paul Munford kit 625. Please telephone 07816

Subject: | More on the use of LED strings |
Friends,
In my last posting on this subject I described hooking up a 5 meter
string of LEDs to a small variable power supply and showing the results.
To me it was quite encouraging and I elected to proceed.
There was some question as to using that power supply in an aircraft as
it was a VPW (Variable Pulse Width) unit. These VPW units are notorious
for introducing considerable electronic noise into aircraft electrical
system. Another variable power supply had to be located.
Eric Jones, proprietor of Perihelion Design, advertised his
Extraordinarily General Purpose Adjustable Voltage Regulator, hereafter
referred to as the EGPAVR, as a low noise variable power supply for both
incandescent and LED lamps. Here is his documentation for the unit:
I ordered a unit which arrived in very short time and connected it up to
my power supply and the LED string.
Here is a picture of the EGPAVR connected to the power supply and the
LED string with the power out to the string coming from the variable
output (yellow lead) of the EGPAVR:
Here is a picture of the EGPAVR connected to the power supply and the
LED string with the power out to the string coming from the constant
output (green lead) of the EGPAVR:
It all seem to work quite well for my application. I plan to use a
short section of the LED string to back-light my fuel sight gage. Power
for this LED string will come from the variable output. The remainder
of the LED string will be used to illuminate the tunnel area of the
Europa and thereby serve as an interior work light. Power for this
string will come from the constant output of the EGPAVR. I=92ll have to
add an inline switch from the constant output to the work LED string.
This is so that the interior work light doesn=92t come on every time the
sight gage is illuminated, it can be turned on only when needed.
Now, if only it will warm up enough for me to get back to work in the
hanger. It has been quite cold here in N.TX. I=92ve tried a couple of
the warmer days to work but still froze. And there=92s no way that
epoxy will set up in this weather. So I work at home in the shop on
other projects.
Next posting on this subject will happen when I have had time &
temperature to install the LED strings and EGPAVR in the aircraft.
Blue skies & tailwinds,

Subject: | Re: Mod 7 flight ready |
The Phoenix has risen from the ashes. Test flight this morning went very well.
No issues and no significant changes.
I was able to pull 3.1 Gs. That is quite a bit of pull. This was both in a wind-up
turn and a straight ahead pull. I didn't feel the need to go beyond that
level. Its quite a dramatic maneuver. Stall characteristics normal. Trim settings
unchanged from pre mod 78.
It took a few days less than 3 months to complete this. Too many hours to fathom.
I hope there are no more such modification to come in the future. Anything
else down the road should seem like a walk in the park compared to this.
I still officially like the change of bolts to flush screws on the CS08 brackets.
Piece of mind.
Thanks to Neville and Bud for all their invaluable help.
