I agree Frans, there will be some heat transfer from the head to thins but not
much. Pistons are cooled by the oil.

| Subject: | Re: LiFeO4 batteries? |
We wrote an article in the Europa Flyer #82 about our EarthX installation (ETX36C).
It is still working fine after 2 years.
We test capacity at each condition inspection with a load test. Lead acid batteries
drop to 1/2 capacity in two years. The LiFePO4 the load test still is over
100 minutes and hasn't changed since we did a benchmark test when it was new.
As Remi experienced, this past winter we saw slower cranking and had a few instances
of kick back while starting. This was because the battery wasn't fully charged.
EarthX reminded us that their technology requires a charge voltage of
at least 14 volts. We added a diode in the C lead to achieve that. Works great!

We have not had any problem with the gas cap leaking and our Europa sits outside
a lot during summer. We disassemble the cap each year during our condition
inspection and lubricate both the outside o ring and the smaller o ring that is
around the shaft using silicone.

| Subject: | Dynon Pitot AOA placement |
I did not research this on the forum before closing my wings - I thought
that I would simply place the Dynon Pitot in the same place as the Europa
original.
I have received the dynon and it has a larger surface area that the europa
item and therefore will exert more stress on the mounting point. it also
has a larger "footprint"
So the options I see are:
1. Putting the dynon in the same place as the Europa pitot but with some
reinforcement ont he outside. I am assuming that if the europa pitot
works in that position then the dynon should work too.
2. Making a new hole which I am loath to do.
3. I saw various options on the forum history including mounting the
dynon on the wing inspection cover. Has anyone done this?
thanks
Will

| Subject: | Door latch microswitches |
I want to take a moment and acknowledge Raimo Tolvio who designed a bulletproof
warning light system to indicate the status of our door latches.
Now that my door gaskets are installed, its obvious, at least in my case, how easy
it is to think the door is safely closed when the rear shoot-pin may not be
engagedbut thanks to Raimo, when my doors are latched I have two green LEDs
on my panel that are quite reassuring.
I opted for greens when doors engage in order to eliminate the possibility of a
false positive if the system were wired to show a red when the doors are NOT
properly engaged.
I also added a grip on each door to allow the pilot to pull either door inwards
to facilitate proper alignment.
The fun will begin soonthanks again Raimo,
Fred

Shortly after I've bought my Europa "it" almost happened also to me, but we've
managed to close the right door in flight.
Never since that day did I forget to check prior to take off by simply looking
over my shoulders and give both doors a firm push.

| Subject: | Re: LiFeO4 batteries? |
The experience on bikes to counter the poor low temperature performance with LiFeO4
batteries is either to leave the headlight on for a short while or just
an initial bout of start cranking, to get the battery internally warmed up.
In any case I find the Rotax starts better if cranked choke on and ignition off
until oil pressure comes up. Then crank with ignition on, which would warm up
a LiFe04 battery.

Subj: Europa-List: Re: LiFeO4 batteries?
I have installed a Super B 7800 Lithium battery one year ago to replace my 5 year
old Odyssey PC545. It works fine but is very sensitive to the ambient temperature;
in summer it cranks the 912S faster than the Odyssey but as soon as the
temp gets below 10 deg.C it seems to crank slower than the old PC545. I did
not have the opportunity to try at freezing temperature up to now.
The battery is installed in place of the Odyssey on the starboard footwell (picture
attached)
Regarding weight and balance, I saved an impressive 5 kg, 4 kgs for the battery
itself and 1 kg after removal of the lead I had bolted to the tail to keep the
balance within limits.
