| Subject: | Re: lower cowl opening for 914 only? |
I had exactly the same experoence. Cut out the opening, discovered I didn't need
to then patched it up with epoxy/bid and filled and faired it. After a short
while running, the heat from the exhaust made the patch turn brown and some blisters
appeared. I refilled the blisters and resprayed the patch then stuck some
aluminium foil over the patch inside the cowl to reflect the heat and haven't
had any further problems since.

Just wanted to mention it's my aircraft that featured in the club
magazine/ LAA Bulletin. G-CGNZ, previously PH-XXS.
I rigged her again yesterday and have not found that the OTHER socket has
a crack and looks like it will detach itself too.
I still haven't' refitted the original, I'm not convinced that it's
important, certainly had no problem rigging without it.

Hi Graeme,
When I built my plane, I also cut out that inlet. It is still open after
10 years and 800 hours and I am not aware of any ill effects. I have
never had any cooling problems and in the winter, I have to partially
mask my oil and water coolers to maintain temperatures. I would suggest
leaving it alone.

Had a sudden panic that I had unnecessarily opened up the lower cowl starboard
NACA duct and that it was only required for 914 inlet and not my 912. I cant see
what its for for the 912ULS as it would only cool the oil tank (which is already
too cool in flight) and possibly one end of the exhaust.
Is it necessary, has anyone filled it in?

Hi Graeme,
I opened it also and installed there a taxi light (HID Xenon =93
check an attachment).
Now if you some day decide to go for 914 you have much less to do!
No reason for panic!

Well, in that case to make you aware of it:
Diverting air, rushing by with a speed of 100+ knots, from a smooth path
alongside the airplane, instead into a hole with lots of obstacles,
sharp turns, etc and letting it out again as a turbulent mass in the
wrong direction and with the wrong speed, is certainly costly in terms
of performance and efficiency. And in this case for no usefull purpose.
Maybe you have invested a lot of effort to make the airplane as smooth
as possible, in that case such a needless source of drag is an even
larger waste.
As a general rule you should close off all unnessecary holes in an
airplane. This is the reason why you have made the covers for the torque
tube access holes. You can leave them off without any ill effects,
except of course a reduction in speed and fuel efficiency.

(on 912)
Hi there All,
Some collateral question about maintaining oil and cylinders temperatures
during cold weather (I have ~70C when external temp is 0C): has anyone
installed some mechanism to deviate fresh air from the radiators, as I have
seen on other home built planes? Any REX?

| Subject: | Maintain temp on cold weather (on 912) |
Max,
For the coolant cooler, I have fitted a shutter (controlled during flight
from inside the cockpit) purchased from Vans Aircraft. See attached photo,
where you will note that approx. 1/3 of the cooler front area is not covered
by the shutter. This is to allow free air flow into the warm air collector
behind the cooler, for heating the cockpit (in warm weather, this collector
is open at the back).
You will also note that the oil cooler is completely covered by aluminum
plates in this winter photo. They are no longer used, as I have since
fitted a Rotax recommended oil thermostat.
This arrangement works very well for me (912 ULS), down to outside air temp
of about - 5 degr C (I don't fly in colder weather!).
Purchasing details - Vans Aircraft, Oregon, USA (as of 2007):
Cooler Shutter - Part Number = EA OIL COOLER VENT Price = $85.00
Bowden Cable Wire End - Part Number = HW WIRE NUT KIT Price = $6.10
72" long Push Pull Cable BLACK - Part Number = CT A-740 BLACK Price = $25.00

Svein

Thomas appears to be at Noumerat Airport in Algeria, just north of the Trans Sahara

Not too crowded by the look of it!

Yep, I'm following it.

Did you notice his airspeed? It appears to be in the 60's most of the
time. Either the logger is lying, or he has a terrible head wind, or he
is aggressively flying in fuel saving mode, or a combination of the
above. I'm too busy to do the math.
Anyway, he has a lot of fuel on board.

Indeed...

Well, that was the case for "just" the last hour or so (maybe he was
getting low on fuel), but his airspeed rarely reaches 100 knots..

Thomas does keep his speed down, fuel flow is kept very low; that's why it
took him 21 hours (wasn't it) to cross the pacific.=0AGraham=0A=0A=0A______
