Re: Long-EZ/COZY/etc. Wing Bolt Retention
Burrall Sanders
We've done this a few times since we built our first Berkut and
realized that it is a good idea. Be careful not to use too flimsy
of material, we discovered one retainer on a Berkut that let the
bolt head spin (half inch all metal lock nuts turn pretty hard) we
had to use a handheld hacksaw blade to cut the bolt to get the wing
off, trust me you don't want to do that. But otherwise, yes its a
good way to retain a wing bolt and eliminate the holes in the wing
needed to gain access to the bolt heads ACS sells an extruded AL.
channel that is strong enough but needs a small amount of material
machined away from the inside to fit the bolt head.

David Froble wrote: As with many things, it's the "idea" or "concept" that is most important. Precisely. And I agree, it's a great idea. However, that clunky piece of metal weighs how much? It's AL - it's a few oz. It seems to me that this part is not structural, and could be much more "flimsy". This particular one could be, yes - it's machined from billet. Redmon's piece is an extrusion, so is lighter. Perhaps even something removable, just like your chunk of foam? That wouldn't prevent bolt rotation, which is 1/2 of the purpose of the thing. If you need a second wrench, you need a 2nd person.

Wire sleeving / protection
Marc J. Zeitlin
Folks: On a different Long-EZ (a very nice OSH award winner), I'm in the process of replacing the ancient Rocky Mountain EMS with a Dynon EMS (along with a Condition Inspection, landing light install, and a few other things). This plane was built with extensive use of wire protection sleeving, such as: and: While pretty, it is not necessary to cover every wire in the plane (or at least 90% of them) with this stuff. It doesn't weigh nothing, and it complicates maintenance, repairs and replacement. Judicious use of either of these, in places where chafing MAY occur (passing through bulkheads or other pass-throughs, etc.) is welcome and desired. Other than that, though, it's overkill and will just make your life difficult down the road. Assume that except for primary structure, you WILL have to maintain/remove/re-install/replace EVERY system (electrical, hydraulic, mechanical) on the plane a few times during the time you fly and maintain it. Make that maintenance easy and simple, and you'll be more likely to keep your plane in good shape and working well, and less likely to ignore things. When installing something, ask yourself how much of a PITA it would be to remove it - do you have to disassemble 1/2 the interior to replace it? Anywhere a nutplate would make life simpler than having to put a wrench on a nut on the backside of something, use a nutplate. Have generous service loops in electrical bundles so that wires can be moved, just in case. Etc., etc., etc.

Long-EZ/COZY/etc. Wing Bolt Retention
Marc J. Zeitlin
Folks: We've discussed this type of thing before, but a Long-EZ I'm working on had a particularly nice outer main spar wing bolt retention scheme that makes it very simple for one person to remove and install the wings. All it requires is one small c'sunk drilled hole in the center between the two outer wing bolts. After the wing bolts are installed in the main spar, this piece is slid over them and a 1/4-28 flathead screw is used to retain the bolt heads; preventing them from turning or pushing back into the spar. The center hole is tapped so the screw pulls it tight against the bolt heads. The inner bolt still needs to be held in place manually - I install it and wedge it in place with a piece of blue foam until I get the nut started. It might be possible to build a 1/2 version of this part to retain the inner wing bolt - haven't tried that, since wedging with a piece of foam works reasonably well. While installing the bolts in the spar is reversed from the plans, this scheme makes it far easier to install the wing. FYI.

Alum instrument panel
Bill Allen
Hi All,
A pal of mine in the UK is replacing his original panel with an alum panel during an instrument upgrade. There is no "education and recreation" category here, so he has to get "permission". The authorities are suggesting that the alum panel (0.125" 2024T3)will be weaker than the original 5 ply BID (2plys one side 3 the other) and will thus need additional bracing. I know that many folk have installed alum panel, and I'm just asking on his behalf, if you have, could you let me know how many attach points, any local beef up, and if you have any "additional bracing" if you thought that the Alum was weaker than the 5ply bid original? Many thanks! Bill Allen LongEz160 N99BA FD51 CZ4 G-BYLZ EGBJ VE N2CR FD51 LongEz diesel G-LEZE EGBJ

Re: Odyssey 680 pickle

That is interesting to me... My 925 has been in the plane now for 7-3/4 years and still going strong as new, never abused but never babied either... I did not realize that there are reported quality issues with the Odysseys. Jay

Re: COZY: Odyssey 680 pickle

I have two due to dual ignition and leave the Odessey charger on all the time. Always starts fine. These batteries are two to three years old now. Maybe I shouldn't have bragged on them. I'll go out and check again tomorrow. Jim

Re: COZY: Odyssey 680 pickle
Craig Westwood
Does the Odyssey have low voltage protection? Meaning it won't charge until it reaches some minimal level? Try connecting another battery and the charger? Or possibly the charger wont charge until and minimal voltage is reached? I left the master on a few months ago (Odyssey 680) and charged it the next day, but it wouldn't turn over more than 2-3 blades, so ordered a new Odyssey... put the old battery on the charger for the heck of it a couple weeks later, and that battery now seems fine... bah.

Re: COZY: Odyssey 680 pickle
Tim Andres
There is a recovery procedure on their web site. Basically you charge and discharge it repeatedly until the capacity is back up. I've done this after leaving a master in and it worked just fine. Also, lots of traffic on these batteries over on VAF about killing them by keeping a trickle charger hooked. I have now experience with that, mine stays up fine for weeks on end without a trickle charge. Tim Andres

Re: Odyssey 680 pickle
PC <uh1cw2@...>
I gave up on Odyssey batteries 6 years ago. I replace Three Odyssey 925 batteries in 9 years and decided enough was enough. By the way, I had tenders on the last two 24/7. I went back to concord 35AXC type. It’s large and powerful. I have had it in the plane for 6 years without issue. It has enough cranking amps to keep the ignition and all electrical in the plane going for at least 2 hours. Odyssey batteries are way over rated and cost a lot of money for poor quality and minimum longevity. Don’t let the bright orange color fool you into believing you’re getting anything special, you’re not!
You are better off with a lawn mower / tractor battery than purchasing an Odyssey.
Just expressing my personal experience with the product.
Respectfully,
Phil Camarda Long EZ Driver

Odyssey 680 pickle
Vance Atkinson
Hey guys,
I went out to the plane this morning to go fly and my Odyssey PC 680 was dead...well, almost, it had 5.2 volts left in it. I was ticked off after doing all the prep for the flight and not being able to go! This is a puzzlement as I flew it last weekend with no problems, and no, I didn't leave anything "on". I checked all the usual suspects and came up with nothing as to why it died. The puzzlement is this battery is only 2.5 years old and not abused. Only gingerly used by a Lil' ol' lady from Pasadena once a year......LOL I have used this type battery in the past and it usually gets to about 5 years before crapping out. I did buy this from a discount house which makes me suspicious. Anyway, scrubbed flight and have a new bat. on the way from ACS. Vance Atkinson
