Calibrate your electric scale and check often. I have an old triple beam (like in chemistry class years ago, yea, I can still use a slide rule too) and I calibrate it at least once a month due to client drips and required gummy clean ups. I use the squeeze bottles from Aircraft spruce for the resin and hardener (throw away after a year) and we still get messy. I don't have much use for the pumps, but if you are doing a Classic wing or Long Eze from scratch in mid summer, they work great for the couple of weeks you need one. Then they need a complete clean out. My two cents thrown on too.

From: david park Hi Richard, Looking back at emails I thing it was around $47 and I found a PayPal item for 37. It is still in packaging, how does 25 sound. I wasn't I sure at the time I ordered it as ac 60 miles away. Later found my cap is the smaller one.

They tolerate being drained more deeply than lead-acid, charge more quickly, and don't have a memory if not fully charged - in fact, if you won't use it for a while it is best to leave it at, say, a 90% charge. However, they are intolerant of being overcharged, and can be ruined that way. A charge profile for a lead-acid battery, with a long float period, will kill it. Lots of people experimenting with these on boat and RV forums. dg On Dec 22, 2014 12:37 PM, "David Park" wrote: > Any battery experts out there can comment on this battery for use in > Europa > 2.2kg? > Dave G-LDVO > > Tracer 12V 16Ah > LiFePO4 Battery Pack > > [image: image1.JPG] > Sent from my iPad > ________________________________ Message 6 _____________________________________ Time: 01:53:46 PM PST US From: Rowland Carson Subject: Europa-List: W26 aft wing socket query I was so pleased that on Friday Id managed to complete the bonding of the wing pin sockets onto the fuselage sides - I had used high-power resistors clamped to each socket and fed from bench power supplies to bring the temperature of the metal parts up to 50C so that the Redux cured in 4 hours instead of 5 days, thus avoiding the need to find a warm and safe place to leave the entire aeroplane assembled for a week. However, when I came to drill the bolt holes through the fuselage hard-points today, I find that despite marking orientations and making several checks, I have managed to bond on the port W26 assembly upside-down - that is, with the small (3/16) bolt hole at the top instead of the bottom. Racking my brains about how to recover from this stupid mistake, I came up with 3 options. (1) Leave it as it is and use the hole at the top. I pretty soon realised this is no good, as the head of the bolt would foul the head of the pip-pin. (2) De-bond the socket with large amounts of heat and do the whole alignment process again, including re-making the shim. This does not appeal for lots of reasons! (3) Drill a new 3/16 hole at the bottom of the W26 flange, taking care to position it correctly. At the moment I cant see any down-side to option 3; can anyone offer any comments one way or the other? in friendship Rowland | Rowland Carson ... that's Rowland with a 'w' ... | http://www.rowlandcarson.org.uk | Skype, Twitter: rowland_carson Facebook: Rowland Carson | pictures: http://picasaweb.google.com/rowlandcarson ________________________________ Message 7 _____________________________________ Time: 02:33:55 PM PST US From: "Bob Harrison" Subject: RE: Europa-List: Lithium battery's Hi! David/all. IMHO it is the capability of the battery to give up it's power when activating the starter . I use two Odessey 13ah STARTER batteries in parallel and my high performance starter gets the 914 into motion instantly. I also have them both mounted on the passenger footwell with the delivery cable only needing to be about 12 inches long . In total it is my opinion that debates about batteries always seems to exclude the basic functions to which I refer here, so beware of short cuts saving weight and purchase prices.
