Single battery ignition and servos
Hi. I want to try using a single life 6.6 volt 3200ma pack in my cmp bf-109.
Thinking of getting the pack with double receiver plugs. Run one to engine ignition (dle 30 or evolution 33) and one to battery.
Also thinking about using a dle v2 opto kill switch. I haven't run a kill switch before.
Do I need to buy something else to insulate the engine noise feeding into flight battery, as it's shared?
Thanks all

But it only has one plug. And it's 4.8volt. Are the 4.8s still safe to use with the 2.4 receivers. I've read they like the 6 volts but its not required?

They prefer 6v but will run on 4.8v provided you don't pull the voltage down with a large load. Personally I prefer the safety factor of a 5 cell or A123 packs.
I have hundreds of flights on 30 and 50 cc single battery setups. Some have two outputs, one to the rx, one to the ignition. In that case you go from the battery to a switch, to the optical kill, then to the ignition.
You can also use a Techaero IBEC which acts as both an ignition kill and a power source pulling from the receiver power to supply the ignition.
Both approaches work well

Thanks barracuda. I think ill just make the switch to 6 volt. I had a big 140 size p-40 go down a couple years ago. I was starting to pull out of a loop. I lost all control and it just went down in a very scale like spin to the ground. I never found out what happened. but it seemed like I just lost all control when it happened.
recently read the receivers will black out if volts drop low so maybe all my digital servos on that plane dropped my voltage to low for the 2.4 receiver?
I guess ill never know, but I like your idea better safe Than Sorry on the volts.
are the hydra max 6 volt packs any good or all you guys just moving on to LIpo/life packs?
thanks again

Here's the thing. If you have a big battery, its probably not going to sag. But A123 chemistry is so much better, I can fully charge in 10 or 12 minutes, so I fly 3 flights and charge, and put back between 40 and 50 percent of my capacity.
Also, you can charge them now and fly them at Christmas, they don't self discharge. I always charge while i'm packing the trailer, that way the batteries are ready to get next time I get to the field, whether its the next day or next month.

For my 109 and larger scale birds I'm goinf all 123. I didnt realize you can recharge them so fast thats great!
Thanks for the info

These newer flight packs sound nice. I have a couple more questions now.
Are the life packs good enough compared to the 123s? I get most of my stuff from tower and they have a lot of life packs.
What I do like about NiMH packs- my batteries in scale planes are buried; And I have charge ports to plug into.
How do you guys charge the 123/ life packs at the field without taking your plane apart? Esp on bigger warbirds/scale planes, as these packs need balance plug hooked to charger.

impala1: I charge/balance my RX batteries through a switch with a charge port using Hangtime Hobbies accessories. Charge cords and switches start about halfway down the page on this link.
http://www.hangtimes.com/a123_packs.html
The system uses the signal wire (generally white) from the battery to the switch as the middle voltage reading for balancing. For some TX/RX systems this may be a problem if an RX uses that wire as the RX voltage reading.

I'm sure others make them, but I get my A123's from WrongWayRC
He will put just about any connector you want on them.
Take my Corvus for an example.
It has a Wrongway A123 pack with three leads. One is a heavy duty harness with a Deans connector. That plugs into a Smart Fly Super Switch, the switch has dual outputs with receiver connectors which plug into two ports on the receiver for extra current capacity.
The second lead has a standard JR connector that goes to a heavy duty JR switch then to an optical kill, then to the ignition.
The third lead is a balance lead which comes with an external charge jack.
I have a Cell Pro Charger with a cable Wrongway made that plugs into the charger and the charge jack to balance charge.
The upfront cost of getting a CellPro and the charge lead is a few bux, but after that, you just order a battery with the connectors you want and you're done.

WrongWayRC also sells Fuse chargeport assembly for the balance lead on A123 packs but you need to buy the charge lead as well see:http://www.shop.wrongwayrc.com/produ...&categoryId=20

Everyone wants things EASY FAST CHEAPER ever think that's Y this country is going to HE[[ in a hand basket. Everyone wants tha latest 100 channel radio and most can't program a simple radio, like a spectrum. JMHO but opinions are like well U know what, everyone has at least one.
Sorry but had a bad day with the phone company cable company and others.
