Well, I don't understand why there are some people who continually blame themselves or "society" for the mean or foolish actions of others.

People who do stupid things that endanger the activities or lives of others are to blame for their actions and should be held responsible for it.  No I'm not talking about errant 10 year old kids that do basically harmless but foolish things I'm talking about people who definitely know better but just don't have the responsibility to care about other people and don't even think about what their actions may mean to them.  The world is full of idiots like that today and "we" are not to blame.  They are!  For whatever reason they choose to ignore the rules of common sense and law and should be chastised for it.  Without that no society can continue to exist!  If you don't believe that just watch the films of Furgeson!!

Evil is Evil and the immortal words of my daughter are true..."Dad...you can't fix STUPID!"  Wise words!

Here it is. Needs some touch up in a couple of minor places. Airbrush job. Then the next color.

I clamped the tail to neutral, with the clevis* in the middle of it's adjustment range.  Then I marked the length of the pushrod by wrapping it with masking tape and using a pen to mark the location of the step in the rod end.  Then I sanded the rod ends and the inside of the rod, mixed up some 30-minute epoxy, and put it all together.

If you do this, and if, like me, you don't drill a pressure relief hole in the rod, you need to clamp the ends on while the glue dries -- otherwise, the slight positive pressure from assembling the thing will push the ends out before the glue sets (ask me how I know!).  Simply wrapping the ends in masking tape takes care of this, and masking tape adhesive usually releases pretty well from epoxy.

* Yes, I'm using a clevis.  I know this isn't necessarily the most reliable means of doing a pushrod, but it's convenient and I suspect that this plane won't last long enough for it to become an issue.

First it was WA,DC...No model flying within 30 miles.  Next it will be NYC...followed by ?  The first time some person is harmed the hammer will come down hard.

We will probably start seeing TV ads by lawyers saying something like "If you have been injured by a drone, call us"

Finally some better weather and some more "field research," or flying.

Data reported is from FMA Cellpro 8 charger, Charge in mah, and % charge.

My Prolite 2700 mah 6 cell packs with Deans are 369.5 gms average and the comparable Zippie 6 cell packs, 370 gms.

Several flights on a few different days have required about 1925 mah "refill" as did the Zippy packs.  The Zippy packs used from 99% full down to 22% full or 77% for 1925 mah and the TPs used only 70% for the same 1925 mah. 

So Zippy full capacity is 1925mah/77% X 100% equals 2500 mah.
The TP pack capacity is 1925mah/70% x 100% equals  2750 mah.

Since I have needed only 1925 mah for the current plane, I have started using a lower charge cutoff, now down to about 4.17 with a C/5 finish rate and then rechecked and had 94% starting charge and finished with 24 and 25% charge on various packs.  Will drop that a little bit and shoot for 92% and 22 - 23%.  Lowering the top charge is supposed to give more cycles over all as noted in early references.  As long as my need is in the 1900 - 1950 mah range/flight that should work.  Of course if 2100 - 2150 is needed, then it will take a full charge and down to about 20% remaining.  Or 79 - 80% of 2700mah is 2160 mah.

At the end of the Zippy life I found what happens as a single cell begins to fade.  The battery really didn't like the overhead 8's.  Apparently use a bit of power and are late in the pattern.  I would experience a subtle softness and loss of line tension and then the battery would seem to recover and finish the pattern.  At flight end, I usually get a slowing and then 1 lap speed up, KR timer, and there was no speed up on that pack.  I got slowing and back to normal speed, no speed up.  On the charger, that pack had one cell with high internal resistance and low voltage, though the charger could "balance" it, so not easily found unless the charger is capable and you are looking.  I tried it a couple of times being very careful, and perhaps not very bright, but in cool minimal wind days and reproduced that finding a few times. It would have been a disaster if unexpected, up high, and in the wind.  On the other hand the Zippy cells were very reliable for over 100 cycles as long as they were used as if the capacity was 2500 mah.  If over used, over discharged, that cell failing may occur without warning and early in the cell life.

Hope that this useful if you are pondering how to spend your battery money.

That's good news! If you paid a company to check this already and they said you needed a new unit I would call them and demand a refund. Leak checking isn't rocket science and any reputable ac tech would should have seen the displaced line...just like you did.

I use about 4 coats of tautening clear on the bare polyspan in the open bays. This makes a huge difference.  I have several planes that are 5 years old now with this process, and they didn't become a pretzel.

Pet e Peterson put me on to this!
