| Subject: | Re: LiFeO4 batteries? |
I have one in a motorbike, which has a Rotax engine with the same potential starter
clutch issues as the 912 (only the parts are a fraction of the cost!). It
resolves starting issues on that.
In a 'plane, I wouldn't be happy with the reduced amp-hour capacity, which won't
keep systems alive for very long if the generator fails. Unless a similar AH
capacity is installed, but the Li4Po is usually sold as a match for CCA, which
comes at much low total AH capacity.

Subj: Europa-List: LiFeO4 batteries?
I need to replace my PC680 AGM battery. The weight advantage of choosing one of
the new generation Lithium iron phosphate batteries is stunning (several kg).
The weight-saving comes at a price premium of course.
Does any Europa owner have one of these LiFeo4 batteries in service and in particular:
1) What is the typical life of these batteries (experience data preferred over
product information)?
2) What UK supplier did you use?
3) If you have a Rotax 912S, which battery did you choose?
4) As a result of the weight save, did you have to relocate the battery to preserve
W&B, and if so where did you site it?
5) Do the LAA care about the fitment of these batteries/any permit complications?
All comment appreciated

I had a Varley Red Top LI-5 fitted for nearly a year. It was ok, but not great.
It needed a fair bit of "warming" before it would turn the engine over fast enough
to start, especially on cold days. With a 5ah capacity I was very wary of
charging phone/iPad without the engine running. After 10 months, my regulator
packed up, although I have no reason to believe this was related to the battery
fitted.
I took out the Varley and fitted a new PC680.

Ask who has experience with the Whirlwind blades, David Joyce has recently
fitted them but not done much flying yet, (approval issues with the LAA)
They look=C2- and sound very nice, much less harsh than the Warp Drive bl
ades.btw 3 blades will be smoother than 2, (which is why 2 blade windmills
fail much sooner than 3 blade ones)

Hello Marcel, all,
yes - I'm fighting symptoms and of course I know, that it would be better t
o rather fix the source of the problems thoroughly instead, which obviously
is, what Frans did (Frans - thanks a lot for your far-reaching explanation
s, your offer to have a look and btw good to know you're well off :-).
I've learned, that most live with the cooling shortcomings of the Europa so
mehow or investigated and found their own ways to cure it (like David Joyce
, who left it all like it is and changed to another propeller). At least I'
ve read about and also saw many interesting solutions. Bud Yerly in Florida
did something different than Frans who did it different than Neville Eyre.
....
What I forgot to tell you, but what is most important for the whole discuss
ion: I didn't build my Europa but bought it second hand. Those who found th
e best solutions are also builders or even worked at Europa Aircraft or hav
e a shop, like Bud. What Frans and Ilona achieved or Bud Yerly does for his
customers is way beyond my skills.=C2-
So I came to the conclusion, that I have to buy a Woodcomp, SR 3000 W, whic
h seems to be an adequate fix for the cooling problem and adds a tad to the
performance as well (since I want to keep the rest of the setup as it is,
like David did, I'd also chose the 3-bladed and not the 2-bladed for that r
eason) or I make a flap in front of the cooler, like a friend in Belgium di
d it at his XS Mono 912S. Another option might be the new Whirlwind blades
with a wider chord in the Airmaster hup http://www.airmasterpropellers.com/
products/productdescription/type/view/id/67/ww-r64w, but I don't know yet i
f this is sufficient, since they are comparatively new. Obviously this woul
d be much cheaper than a new Woodcomp with Controller.
At least my "only" cooling problem is SOLELY ON THE GROUND and in a couple
of years, even though running the engine with a thermostat I never actually
had to shut down the engine due to overheating. So I have to focus on that
problem during ground operation.
Anyway thanks again to all for your input - much appreciated!!

Hi Clive,
I'm using a SuperB 7800 in my Europa (912) since three years with the standa
rd Ducati regulator; didn't have any problem with it even in very cold winte
r conditions here in Austria! Never had to recharge it either!
The Ducati regulator delivers 14,2V which is exactly what is needed and spec
ified by SuperB to charge the LiFe cells!
The battery is mounted on the right side, top of the footwell.
Before I had an Odyssey Battery PC545 at the same place; CG still ok.
http://www.super-b.com/en/aviation/sb12v7800p-cc
(we have the same Battery in a LOM powered B=C3=BCcker and in a Lycoming pow
ered Christen Eagle)
Cheers,
Klaus

I'll check the Whirlwind option as well. The performance improvement seems to be
quite similar to the Woodcomp. Unfortunately they are not plug and play and
some modifications to the hub/rootes are necessary. I spoke to Martin from Airmaster
at the AERO fare.
Good thing is, that the LAA doesn't have me over a barrel any longer, since my
Europa is Dutch registered now :-)

David, why are you testing the Whirlwind blades? You wrote, that you are satisfied
with the Woodcomp. Anyway I would be very interested in the results, especially
how/if they improve cooling, since you have a similar setup (I guess there's
not such a big difference between Mono and Trigear).

| Subject: | Report: Nye grease nose-wheel fork friction |
Just over 3 years ago I got my mono converted to tri-gear and it was suggested
to use the Nye product as a means of enabling the nose-wheel to castor smoothly
i.e. no jerky snatching when initiating turns with brakes. Because this grease
can also be used as a lubricant, I applied it to the spindle and bronze bushes.
This was an excellent idea which has worked smoothly and trouble free during over
200 hours and about 250 flights. As time goes by the grease on the friction
disc gradually gets squeezed out around the edge of the disc and needs to be
wiped away.
A couple of flights ago I experienced slight nose-wheel shimmy while landing and
therefore tightened the nut at the top of the spindle, before making another
flight and getting a repeat of the shimmy.
So today I removed the nose-wheel fork and was slightly surprised to discover that
there were only a few slight traces of Nye grease on the friction disc, which
had become glass smooth and dry without any stickiness. The grease remaining
on the spindle and the bushes had become somewhat less sticky and was quite
easy to wipe away.
All metal surfaces were corrosion free, unmarked and look new, so the grease definitely
lubricates and protects. Following thorough cleaning with acetone and
paper towel, I applied new grease as before and reassembled, checking that the
nose-wheel fork has similar resistance to being turned.
Hindsight is marvellous and I thought when driving home that perhaps I should have
slightly roughened the friction disc to give the grease a better surface to
hold. Ah well, next time!

I also used sticky grease! Can't remember name, it's in the hangar. I found it
difficult to turn on the brakes and have reverted to the original system. Will
compare you product with mine?
