@Nigel, red blinking is the annunciation that you are above 160knots (about Vne)
for line 7. In this case, gear is up.
When gear is down and above 80knots, line 3 becomes relevant and the annunciation
is green blinking.
So basically when something is wrong with speed/gear, you get a blinking led.
When the situation is "normal", you get a steady led: red for gear up and green
for gear down.

I cant find any mention in any of my build manuals of the NACA scoop mouldings
that came with my XS kit, or how and where to fit them.
I notice that other builders appear to have made their own choices of location
- see the composite picture in my dropbox at:
https://www.dropbox.com/s/hkyd4ldm1x634id/scoop_locations.jpg?dl=0
Id like to site my scoops in a way that makes it easy to fit eyeball vents on the
inside; as the eyeball vents Ive got have their own on-off control I dont plan
to use the adjustment feature supplied (one of which broke anyway within minutes
of unwrapping it). Id prefer to avoid the need to construct serpentine
ductwork (as related recently in The Europa Flyer) and want to keep the eyeball
vents clear of my knees. I imagine that lower locations are more likely to be
high-pressure and higher locations less so or even low-pressure, but I wonder
if there are any real no-go areas.
The fitting instructions packed with the scoops (made by Ayton & Co & supplied
through Aircraft Spruce) show how to fit the scoops on the inside face of the
aircraft skin, but as the flange is only about 2mm recessed from the outer surface
of the scoops I think it will be necessary to cut back the inner skin to
allow them to sit flush with the outer skin.
All input on this topic welcome!

| Subject: | top cowl carb air inlet |
Ive bought Neville Eyres cowl set and I am wondering how to get the air into the
cowling to the plenum chamber for the carbs.
The Europa manual describes making a NACA duct on the top cowl to connect to the
plenum chamber, at a marked position. If I understand the manual correctly,
it appears that a buck or splash moulding is supplied with the factory cowl set.
It is pushed through the cowl from the outside and the duct is laid up inside
the cowl against the splash moulding.
Neville has not supplied anything to make the NACA duct for the plenum chamber.
Obviously I can work out the position on the cowl from careful measurement of
the plenum relative to the firewall, but I dont have any information or pattern
for the shape and size of the NACA duct.
Does anyone have one of these splash mouldings from the factory that I could borrow,
please? I dont need it right now, but want to make sure I have some way
of dealing with this problem when I come to it.
Or, if Im not understanding how the NACA duct is made, can someone please explain
it to me!

Nev,s cowling uses baffles similar to a Lycoming/Continental, no plenum needed.
Pictures to follow.

Rowland, I have the Nev Eyre cowl set as well (though not yet built) and my understanding
is that it does away with the fresh air inlet by guiding fresh air
over the top of the engine from the cooling ducts immediately behind the prop
- as a result, you simply put "normal" Rotax air filters onto the carb inlets
and use air from directly inside the cowling. There is a picture of this set
up on the Europa website where Nev's cowls are shown with the top off.

Ive had a reply already offering the splash moulding when I need it, and I have
also spotted a picture of the thing itself posted by Bob Harrison on 18 June
2014, showing what some folk use it for after the build is complete.
However, Ive been studying the manual again and I notice that in the instructions
for making the rectangular flange to support the rubber skirt that seals around
the air filter, it says:
"Make cardboard formers in the manner described for the [NACA duct] side pieces
which suggests that there was an older method which has not been completely excised
from the manual. Im guessing that this approach used the piece cut out of
the cowl as the ramp and cardboard formers were used to support the layup of
the sides of the duct.
Just out of interest, does anyone have a copy of a previous version of the firewall
forward manual that includes a different recipe for making the inlet duct
that involves cardboard formers?

Ive looked on the Europa factory website and cant find any pictures of or reference

Hi Rowland
I have just posted photos of nev's kit installed in my aircraft. When i done my
install there was no documentation from Nev. U had a good chat with him and
got a good understanding of how everything was to be fitted. It actually goes
together pretty easily.
Should you need any advice or guidance feel free to get in touch with me and i
will try my best to help as much as i can. If i can remember.
Regards
Donald

There was a recommended position from Europa for the NACA vent but I can't
lay my hands on it at present. From memory it was along the split line of
the top and bottom of the 'canoe'. I thought it was in the Company Tech
talks but I have failed to find it.
Hope this gives a pointer.
