Hi! Tony /Troy /All interested.
The restrictor in the fuel return line is purely to return a minimal ammount
of hot fuel back to tank. If you had a big flow you'd finish up heating all
the fuel in the tank..... somewhat pointless then having a return to tank
line!????

Gidday,
I have been following this thread for a while, because I started it. I am
surprised there isn't anything definitive, but I appreciate there is a
difference between ID and OD. I do however "not" have my head around why you
would need a restrictor in any fuel return line, irrespective of engine
type?
Superficially, or based on "downunder" common sense (dare I say it......and
I
have this horrible feeling I am about to eat dirt ), but, it doesn't gel.
So,
why is it so? and why isn't there a bit more defiinitive answers to the fuel
dimension questions?
Reg
Anonymous, until I work out if I am right or not.
P.S. Yes, I know this is a falacy.

I think the restrictor is also needed to maintain pressure in the lines between
the pump and the carbs. Without the restrictor the pressure would drop to almost
nothing. Think in terms of the pressure you get in a watering hose when you
put your finger over the end and only let a small amount out, compared to the
pressure in the hose when you allow full flow.

The 914 is different, it uses rotary fuel pumps which delivery far more
fuel than the engine requires. This is the reason the 914 needs a bigger
return pipe dia than the 912s. 912s have a mechanical pump,
displacement dependant on engine rpm so delivery is much more limited.
Excessive return flow would cause reduced fuel pressure, which might not be
enough to avoid fuel starvation. The Facet electric auxiliary pump also has
limited displacement and won't give enough pressure to compensate.
Incidentally, the limited displacement/flow rate also makes the engine more
susceptible to vapour locking because the pumps have no way of catching up
the deficit caused by the vapour. Hence the importance of the return pipe,
it bipasses the vapour quickly and gets cool fuel to the pump. The pump
absorbs heat from the gearbox, which is heated by engine oil.
BTW there is no such thing as a daft question. How else can one learn?

Dear Tony Renshaw
When setting your tufnol bearings, the distance between the two torque tubes
at the rear is critical. It did not say "critical" in the manual page 13-6
of jan 1996, but the distance apart must match exactly the distance apart
of the connections on the factory made pitch torque tube and that yu will
will come to soon. Then you will see that there is only tiny tolerance
between the rivets in the CS07's and the pitch push rods so your riveting of
the CS07's needs to be correct too. I got my torque tubes about 1/8 inch too
far apart and did not find out find out until later when installing the push
rods through their middles. That is when I found out that the rivets in the
CS07's would touch on the pitch push rods preventing full and clear
operation. so I had to go back and change the distance and t hen relieve the
tufnol at the front to line it up again.
Get the distance between the two torque tubes at the rear exactly right the
first time!

Hi All,
I recently got an e-mail from a builder who was under the impression that
trailers were not available in the US. This surprised me, as I have had
trailers in stock for the last 3 months, and have always been able to order
them here.
If anyone wants a trailer, please give me a call at 863-647-5355.
Thanks!!

Peter,
The Grand Rapids EIS does have the ability to use two fuel flow transducers, thus
resulting in "net" fuel flow. They are very attuned to Rotax 914 and specifically
Europa installations, the fuel level probe supplied by Europa is the identical
unit that Grand Rapids sells to interface with the EIS.

| Subject: | Engine Vibration & Shock Mounts |
--> Europa-List message posted by: "Europa Aircraft" <europa@gate.net>
Hi All,
Recently some US builders have asked me about using softer shock mounts than
are supplied with the kit. After changing the shock mounts to the softer
lord, or "O-200 type" on the 914UL factory demonstrator in the US, we
noticed no improvements. Prior the instillation, the engine was properly
balanced. We did, however notice an improvement on another 914UL engine
that had abnormal vibrations after installing the softer mounts.
If the engine is properly balanced in accordance with Rotax service letter
SL-912-010, and running correctly then there should be little vibration with
the factory supplied mounts. However, if the engine is rough, or the prop
is out of balance, than there may be detectable vibration with the factory
supplied mounts.
Softer mounts, however can cause other problems, especially with the 912ULS,
or 912ULSFR as this engine has a higher compression, and can kick back
violently if there is gearbox problem, or if started improperly. The softer
mounts can allow the engine to thrash around when starting, possible
throwing of the air box, carburetors, and various other important parts that
you want secure when you fly.
Hope this helps!

Hi John,
I am delighted to hear about the trailers. I too did not know they were
available here.
As you might guess I am interested in a trigear trailer and was preparing
to build my
own.
May I suggest to you and Keith that the Europa Catalog, with pictures of
the various
items (and specs for things like trailers) be made available on the web. I
think its
been more than a year since I received a paper copy and to tell the truth,
I'd rather
have big color pictures to look at than grainy small b/w ones in a
xerographed catalog.
Would anyone in the Europa community care to second this suggestion?

...i have purchased the dual flowscan sesnsors from grandrapids. The eis will
do all the mathematics and you get the net figure...easy!! You pay twice the
price $750.00 for the dual sensors but you have to let Greg know in advance
so as to configure the eis for that particular mode.

Could I get the measurements of the trailer with the mono wheel aircraft on
it. I want to see if it would fit into the garage with the car. If it does
not fit then I will have to rig up an enclosed trailer for the aircraft.
Thanks
Allan
