Do you run your DA twin of an A123 pack?
Do you run your DA twin of an A123 pack?
If so, which MA pack and how many flights do you get between charges?
Do you use a regulator?
Have you had an ignition failure?
Many thanks,
Branwell

RE: Do you run your DA twin of an A123 pack?
I have setup DA150 /170 etc.,ZDZ160 etc all with A123 1100ma and 2300ma packs
I will not use regulators the little pack will do 5 flights easily The non regulated packs have extremely stable voltage AND amperage as there is no interferrence from a reg. .
stable voltage for effective life of a charge is aprox 6.5 volts If you want to nit pic- 6.6-6.3

RE: Do you run your DA twin of an A123 pack?
I have six 50cc planes now running on a SINGLE A123 2300ma battery.. Mainly DL 50s
We install ONE IN4001 diode on the + side of the ignition , keeps the voltage at 6VDC at all times..
Just learned this from Jody at Valley View..
Have been flying at least a year six planes without the diode but one A123 for the entire plane..
But all 50cc, Turning on everything at once keeps the battery at 6VCD
This is more important if you use ONE A123 for the ignition.... 50 cents could save ONE BIG PROBLEM.....

We have a DA150 that we (my partner and I) are going to be flying on a 2300 mah A123 battery pack. I have an e-mail from DA says that this is OK.
"50 cents could save ONE BIG PROBLEM". I would like to know specifically what big problem you are talking about. Is this big problem documented any where? Should I be worried? I totally understand the function of the diode but you are introducing one more failure point. By the way the diode is a 1N4001 and not a IN4001.

RE: Do you run your DA twin of an A123 pack?
DL and DA are not thesame ignitions. He's talking about DLneeding the diode for A123. Apparently DA sends e-mails blessing the A123 but doesn't put it intheir manuals.
PS: Per my electronics engineering guru at work, the diode is very reliable as long as you keep it cool. They do get hot...just like regulators. Diodes have a voltage drop across them and pass current that the ignition draws. So that equals power dissipated in heat. Just don't wrap the diode up too well. Let it breathe.

Hi Ken,
The ONEBIGPROBLEM is running an ignition that say 6VDC ONLY at 7.25 volts like a DL ignition...
DAignitions are rated way above 6vdc...Diods are NOT needed for DA
Sorry I guess I strayed off the topic

Do DA's ignitions have any benefit to running a lower voltage? Like running cooler?

Excellent question!

RE: Do you run your DA twin of an A123 pack?
Check out this link on CHIgnitions website http://www.ch-ignitions.com/tech.html#chxl specifically talking about the RCEXLignitions, but some good info about ignition voltage, operating temperatures, 'spark', etc.. that Isuspect would hold true for most ignition units.... looks like a higher voltage pack isn't necessarily a necessity.

Yes.
1200 to 2300 packs - depending on the application.
Seems to consume about 150 to 200mah per flight so far - both DA-100 and 100L.
I use a regulator and I know it is not necessary with these packs, but I can't help it
No ignition failures at all. I use the same setup on RCExcel ignitions as well.
