Perhaps a reaction to Brexit - But they didnt give me an explanation! 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.

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!

From: Kingsley Hurst 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.

Here's a link if you are EAA Member: https://eaa.org/Videos/6101193115001 > If not: put cable in vise gently, chuck end of cable with a drill that has very 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.

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.
