Richard - sorry for late response - your message got stuck in spam. I had no problem
purchasing the GR6 from Herr Schicke for delivery to Cheltenham UK, but
that was back in 2012. He sent me a pro-forma invoice by e-mail and I paid by
Swift bank transfer. Perhaps something has changed in the last few years.

Hi Group A bit confused after reading this thread. Is someone really using a LiPo
battery on an aircraft you fly in? I'm assuming LiPo you mean Lithium Polymer
battery. They have one of the best energy densities around and can dump amps
like crazy if designed to do. They have a better Energy Density than Lithium
Ion. That said they are also incredibly dangerous. Far worst than Lithium Ion.
Great stuff for models and if you charge them somewhere that when they catch
fire and you have a big bag of sand in a plastic bag over them so they don't
burn down your house or whatever else they are near. It's not unheard of for model
guys to lose their car by recharging inside them.
Anyway is someone with a Europa really flying with LiPo??
I never heard of a LiPro, what is that?
Earth-X batteries are LiFePO4 Lithium Iron Phosphate. It's a fairly safe Lithium
technology, I think Earth-X has their act together as far as making it aeroplane
friendly with their balancing, protection and shut down. They have a worst
energy density compared to Lithium Ion Batteries but safer.
I agree that when using batteries that can dump amps and are light weight, just
because they can start your motor, their capacity may be very limited. Another
thing is to consider is just because a battery Mfg. lists a specification does
not mean for one thing that it's true and another if they give you a capacity
when discharge at 1/20thC, in other words whatever capacity the battery is
you discharge it over a 20 hour period, it will not be the same as draining the
battery over an hour or two. Same goes for 1/10C. If you are relying on the
battery to provide power in the event of a charging failure, you really must
do an actual test. Figures don't lie, but liars sure do figure! Ron Parigoris

Subject: | Re: Has anyone Twist Welded Cables? |
Hello Ron,
I have never seen that trick before so thanks for the heads up. Provided
one has plenty of cable available, it would certainly be a solution to
the splayed ends on the cable.
I achieved a satisfactory result by gently soldering the end of the
cables. I guess dipping them in some epoxy would also work but I
haven't tried that.
Best regards
Kingsley in Oz.

slow speed, slowly heat with Propane torch till cherry red then pull and run
drill on very slow till cable breaks. You damaged the plating so take end and
dip in self etch primer or similar. Ron Parigoris

Hello world,
I rarely post in this list, but I achieved a major milestone that I felt
urged to share with you. In process of finishing build of my MG wings. Mod
78 already done, closing stb wing. See the pics.

In the UK the LAA Technical leaflet 3.26 which refers to Standard Modification
SM14337 - Lithium Iron Phosphate Batteries LiFePO are the approved standard for
use in LAA aircraft,. I use one in mine and I believe several others do.
What others are using outside of UK I couldnt say. Maybe people are confusing terminology.

No confusion Alan, just a good old typing without my glasses on. Battery is indeed
a LiFePO4 sent from Germany for 80 with the last one lasting five years.
