| Subject: | Oil Pressure Switch for engine hourmeter |
I have an air pressure switch fitted to both my aircraft. Idea that came from the
old Gliding spares company who I can't remember their name Maybe RD?
Measures Pitot/static pressure and is set to 40 knots. It switches a miniature
Farnell hour meter (RS in the old Jab but I couldn't find one 3 years back). About
50 all in.
Radio Spares part number 317-443 Calibrated by gently sucking 40 knots on the static
line reading on the ASI with a meter across the switch.
I find this is very accurate as it measures hours with the engine under 'load',
the only thing I care about.
The difference in actual engine running hours and flying hours is about 12%, that
is an average over 1100 hrs (last time I looked).
That is flying from my base where engine running apart from flying is purely to
warm the engine up and less than 50% of the time back tracking (prevailing SW)
a 500 metre runway..
I do of course 'get about' and at some places taxiing can be a long time but maybe
good average to use..
Oil pressure switches or anything else are just a compromise for engine load hours
but the good thing is they will usually make you over maintain.
There are gadgets on the TV screen things that maybe can do this for you but I'm
still steam driven as I built before the TV thingy's were reliable.
Just myho, Regards, Clive

if anybody has flown with this combination:
Jabiru 3300 engine, Whirlwind prop 65", straight exhaust pipes?
If so what was your performance figures? Is there anything I should watch out
for?

Jabiru is not a good solution! I know many engines for sales in France replaced
by Rotax. <<Reliability>>

| Subject: | Re: Landing and Taxi Light Question? |
Hi Jeffrey,
I mounted my light at the top of the left outrigger fairing. It is a 35w
'taxilight' with a conventional bulb. However, the illumination is
really not very satisfactory. One day, I will mount an HID light in the
same spot. I plan to use a light from Trail Tech
<http://www.trailtech.net/index.html>. I think a 30 watt HID SCMR16 #
4252-SX will meet my needs. See catalog
<http://www.trailtech.net/media/catalog/TT-CAT-09_lowres.pdf>.
I also intend to look at using a 'snowdome
<http://www.snowdomes.com/mm5/merchant.mvc?Screen=kit2medround_info> for
a fairing. This idea was posted earlier by a very creative Europaphile.
Cheers, John

EGT and CHT are all you will need to be careful of.=C2- I am in the middl

=C2- One of the secrets seems to be the amount of twist in the prop near
the hub, so that it throws a lot of air into the cooling ports.=C2- This
is why the Senesenitch is recommended.=C2- I don't know anything about th

Just on Raimo's and johns note on the hid lights, you might find this
site
useful www.hid50.com I have not purchased anything from him yet,
but
the prices seem good, and he has a lot of good information that is
worth
a read if considering HID. Only problem is he sells just the bulbs and
balasts
no lights to put them in, so you need to find a suitable light to take
the
bulb, my thoughts were some of the new motorcycle lights are just
about
the right size and could be dismantled and fitted into the cowl.

Carburation affects cooling. The carb needs air going straight in
evenly, a smooth elbow into the carb doesn't work, different air
velocity across the inlet which causes different mixture in the front
and rear cylinders, (I'm thinking aloud here) could be that turbulent
flow is needed. A plenum that feds straight not curved seems to work
better. A box with in and out tubes @90deg works. Turbulence might help
evaporate the fuel droplets spraying into the inlet manifolds. Drops
won't go round corners.
There's a guy in UK who worked this out, Anthony Higgins but I don't
have his contact details, (@#%$^&windoze crash :-( Rally driver and
Europa builder. Are you there Tony?
Tony helped cure an overheating Jab 6, I spent hours on it and failed.
Which reminds me, I recommend you fit a fuel bleed back downstream of th
engine driven pump. Pump is bolted to the engine and will get hot, fuel
vaporisation is a possibility. One accident due to this suspected, not
yet proven. Fuel was Avgas.

Graham-
I have been talking with the Jab. people in Tenn. as I go throught it and I
purchased one of the little 30 degree elbows from them.=C2- Jab. also re
commends thoroughly smoothing the area around the 2 1/4 inch tube leading o
ut of the airbox and I have done so.=C2- This would all seem to support a
smooth flow, but at this point I know nothing, since it is not yet running
.=C2- As an initial shot, I am going 100% with the Jab. recommendations,
then we will see.=C2- Their feeling is that cooling will be OK.=C2- The
more recent engines (mine being one) have larger fins on 5 and 6, and they
say this helps.=C2- Also, on the tri-gear, there is an easier exit for c
ooling air, and that supposedly helps too.=C2- I have individual EGT prob
es on each cylinder, so will be able to watch it.=C2- Also, they say that
the baffles you can install in the cooling shrouds can be tuned to get it
just right.=C2- As I say, I have no way of knowing if any on this is corr
ect.=C2- Talk to me in about 3 months.
You can also install pipes off the cooling shroud pointed at components you
wish to cool, and I may find it necessary to do that with the fuel pump.
=C2-
