[NSRCA-discussion] Changing list behavior.

Mon Mar 27 15:25:58 AKST 2006

In other words, the subject matter......... "Changing Behavior"......... was aptly named. Electric powerplants are all about that.

And also to Jimbo's point, if Pattern wasn't a flying event before, it sure is now.

>From my brief personal experience and equipment and watching others, it takes a different mentality to run electrics.  If you like to tinker with things, it will drive you crazy that there is "nothing" to do to an electric motor (unless you change grease on a gear box).  With the Plett, there is NOTHING to do - it either works or it doesn't.  

The only thing to really "adjust" or setup is the controller.  After that - as a user - all you do is record temps and do not fly too long. The worse thing you can do is fly too long and run the batteries too low. Then, you charge the batteries using the best practices for that equipment.  That's it..

When you get home, there is typically "nothing" to do to the plane - just be happy to let it sit on the shelf until you fly again J  It's a different mentality, but the benefits speak for themselves.

Thanks,
Jim W.

I like getting ALL the information so I can make my own decisions.
My involvement with the electrics is stalled and likely to remain that way until the battery manufacture's release product specs in the parameters that we are operating. Like charge-discharge data in the 10C to 25C range. 

I use LiPo's, NiMh and NIcds in assorted gadgets within Manufacturer specs with great success. 
I am reluctant to spend my resources to test a vendors product.
Keep the data coming, the messenger with bad news has always been punished!

Jim,
       I'm not anti-electric. But if I reported that I had blown a rod on a YS DZ I perceive that I would get a different reaction than if I report a problem with an electric motor or its set-up. 

If I succeeded in getting one pilot to take care of their batteries in a safer way then it was worth running the gauntlet of my usual critics on this list.

Regards,

Eric.

BTW - Rules proposals are the last thing on my mind. I'll leave that to the NSRCA board and the survey results etc. Nor would I want to separate pilots. Rewarding private and funded pilots is a different issue.

Hey Eric,

After your last emails about the charging incident, I was sure you'd follow it up with some sort of rule change proposal.  I was guessing you would start with an outright ban on electrics J, and not a separation of pilots.

I have noticed a behavioral change in this discussion list over the years when it comes to electric power. There was always some polarization to Radios and engines etc.

What I noticed most was that the glow era engine owners were very willing to report their engine failures and a whole myriad of engine fixes and preventative medicine.

I still see the latter but not as much of the failure reporting. I put this down to sponsored pilot behavior with all products. I also noted a change at the top. Now most all the pilots are sponsored in one form or another. We always had a few sponsored pilots but now the unsponsored pilot is the exception.

Maybe it is time to have a Pro-Am separation in the awards?

I also noticed that the list does a lot more advertising/selling that it was ever intended to. That may be or not may be a good thing.

Judging by my off-list in-box a lot of folks do not post on the list what they think for fear of retributional responses. "Nil illegitium carborundom men!"

Regards,

Eric.

Nope!,...... I think that I might have also had a similar experience with the Astro charger. 
I had a pak that had been in storage for about 3 weeks and decided to top it off before flying, but noticed when I connected it to the charger that it started out at the maximum voltage and started increasing from there into territory I had never seen before.Recognizing that I had never seen voltages this high displayed on the screen before, I immediately terminated the charge. This all happened within a period of 15-20 seconds.

 What everybody is assuming is that this was a screw up.It could also just have been a bad cell The manual does say not to put a fully charged pack on the charger and discharge first if any doubt.

I can't say how the charger works, but my uneducated guess would be that the voltage rise (internal impedance) with the application of current would be different between charged/uncharged cells.

What still bothers me is:- If 3 fully charged cells = 12 V plus, and 4 
discharged cells = 12 V Plus, then how does the charger know which is which?
